The Block Editor

The Block Editor is designed to simplify the creation process, making adding content intuitive without overloading you with expansive toolbars that you'll never want to use. However, this does not mean that its functionality is diminished; with the block editor you can style and modify your text, insert media, galleries or video embeds, and adjust layouts and styles with just a few clicks. The block editor also displays content as it will appear on your site, so you can adjust it until it looks just the way you want. 

The Block Editor Workspace

So what makes the Block Editor different from a regular editor or word processor? The key difference is that each paragraph of text, each list, and each image, gallery, video or other inserted media are placed into their own 'block' of space in the editor. This makes it incredibly easy to use; instead of needing to copy and paste elements around the page to reorder your content, or add HTML tags to style it, you can just use the controls to move and style each individual block separately. 

You can't actually see the majority of these controls when you start writing though; to keep the writing process clean and unobtrusive the options are hidden away until they're needed. With just a few clicks, you can add media, style content, and perform a multitude of other functions. But let's start with the basics:

Adding a Post Title

A post title is one of the required elements before a post can be published, along with the main content in the body of the article. When first loading up the block editor you'll see a field marked as Add Post Title; click on this and add your title text before (the placeholder text will disappear when you click on the field).

Creating Blocks

In a new post you'll see some placeholder text where the first block begins:

Blank block editor post

Click on the 'Start writing...' text to place the cursor and start writing your first bit of content. To create a new block, simply hit enter when you finish the paragraph; this will automatically create a new block for your next paragraph. In fact, hitting enter at any time when the cursor is active in a block will create a new block underneath the current block. Alternatively, you can hover your mouse cursor over a block; you'll see a blue plus sign appear under the centre of the current block. Clicking this icon will also create a new block.

Modifying Content

The Block Editor in Publii provides all the functionalities that you'd expect from an editor, and more besides. However, unlike other editors that include extensive, intrusive toolbars at all times, the block editor's toolbars are hidden by default, opening only when needed. A key element of getting the most from the block editor is understanding where these toolbars are, what they do, and how to access them. For the sake of clarity, we will refer to these toolbars as the Insert Toolbar, the Conversion Toolbar, the Formatting Toolbar, and the Inline Editor

The Insert Bar is only available when a block has no content inside it, as the functions that it applies require the entire block. It may be opened by clicking on the block that you want to modify, then clicking the Plus icon to the left of the block.

Inserting block bar

The Conversion and Formatting Toolbars allow for content in an existing block to be modified at any time; useful if you change your mind during editing. The Formatting Toolbar will be especially important as we move through the various functions included in the Block Editor; if there are any feature-specific options, they will appear in this toolbar. To access these toolbars, click on the block you wish to modify, then click on the Ellipses icon to the right of the block; the toolbars will appear at the top-left and the top-right of the block:

Opening the conversion and formatting toolbars

Finally, the Inline Editor provides text formatting options such as adding bold or underline text, as well as links. To open the inline editor, highlight the text that you wish to modify and the inline editor will appear

The inline editor interface

With that out of the way, lets take a look at the functions available in each of the toolbars.

The Insert Bar

A good post should include something other than just plain text, whether that's media such as images, galleries and video embeds, stylistic elements such as dividers, lists and a table of contents, or alternative text modes such as code, quotes and headers. In the block editor, these elements are inserted via a separate toolbar, which we'll refer to as the Insert Bar. To see the insert bar, click on the block that you want to modify, then click on the blue plus sign that appears to the left of the block:

Inserting new block bar icon

Note: The icon to open the insert bar will not appear if the block already has content in it; this is because the elements that can be added to the post via the insert bar should be contained in their own block to ensure the styling and other elements work correctly.

The insert bar functionalities are, starting from the left icon and moving to the right:

  • Insert a Header.
  • Insert an Image.
  • Insert a Gallery.
  • Convert the block to a List.
  • Convert the block to a Quotation.
  • Convert the block to Display Code.
  • Convert the block to HTML.
  • Insert a Divider.
  • Insert a Readmore.
  • Insert a Table of Contents.

In addition, you can also use the following keyboard shortcuts:


Let's take a look at exactly what these functions do!


The first icon, which looks like a letter H, converts your blo.pngck to a header which is important for adding titles and subtitles to your text. This is useful not just for the aesthetics, but also as properly-used headers can be useful for SEO, improving your findability in search engines.

Clicking on the header icon will, by default, convert your block to an H2 header, since usually the H1 should be used only once in the post title. However, you may convert your block to any header from H1 to H6 using their respective icons that appear in the Formatting Toolbar after clicking the header icon.

Headings editor block

Inserting Images

The second icon in the Insert Bar allows you to insert an image into the block. Clicking on this icon will create an image block, where you may then drag and drop an image file into the grey area to insert the image, or click on the Select File button to open your computer's file explorer to choose a file.

Images editor block

Once a picture has been chosen it will be added to the block; at this point, there are multiple additional options available for styling and adding captions and other elements to the image.

To add a caption and alt-text to your image, insert your text in the respective fields underneath the image. For styling your image, you can use the Formatting Toolbar which is accessible at the top of the image; the functions in this toolbar are covered in the next section of this guide.

Styling Your Image

There are also several styling options available via the Formatting Toolbar. Click on the image, then on the Ellipses icon on the right of the block to open the toolbar. From there, you will see a set of six icons, each providing a different function. 

image editing toolbar

The first three icons in this section allow you to select the size of the image on the page; the first icon sets the image to be slightly smaller than the width of the text, the second icon sets the image to be slightly wider than the text, and the third icon sets the width to the full size of the page. The image will be dynamically scaled to show each option as it is chosen, so feel free to test them all to see which one works for you!

Creating a Link in the Image

You may wish to add a link to the image, rather than leaving it as a purely static element. 

The chain icon in the formatting toolbar allows for the image to include a link to a different part of your site, to an external site, or to a specific file. To insert a link, open the formatting toolbar and click on the chain insert link icon. 

Adding CSS Classes and IDs to the Image

For users that want to have more complete control over how the image is displayed by targeting it specifically in CSS, you may add a CSS class or an ID to the image via the Settings icon, the fifth icon in the formatting toolbar for images.

Clicking on the Gear icon will open the settings pop-up. From here, you can add your CSS class or ID into their respective fields, then click the Save button to close the pop-up and apply your changes.

Deleting an Image

If you decide that you don't want to use the image in your post anymore, you may delete it by clicking on the last icon of the formatting toolbar, the Bin icon. To prevent accidental deletion you will need to click on this icon twice before the image will be deleted; on the first click you will see the bin icon change to be open, then a second click will confirm deletion.

You can also delete an image by hovering your cursor over the image, then clicking the Red Bin icon that appears in the top-left of the image to delete with one click.

Inserting Galleries

If you have a large number of pictures that you want to display, then a gallery offers a simple but elegant solution. An unlimited amount of pictures can be added to a gallery, which will be displayed in a column-style format that will adjust the position of the pictures automatically to fit the screen size effectively:

Gallery example

To create a gallery, click on the third icon in the Insert Bar, which looks like a stack of pictures. Just like when you are inserting a standard picture a grey section will appear where you can drag and drop your files, or click on the Select Files button to grab your images via the file manager.

Modifying the Gallery

Opening the Formatting Toolbar will display largely the same options as when you are inserting a single image, with icons for setting the width of the gallery. However, there will also be one additional option, Columns. Changing the number here will adjust the number of columns that the images are sorted into. 

Editing gallery

Otherwise, deleting and adding CSS and IDs to your images will function the same as detailed above in the Inserting Images section.


 The fourth icon in the Insert Bar, which looks like a list of 3 dots and dashes, inserts a List into the block. A list can be unordered, which uses bulletpoints for each item, or ordered, which adds a number to each item, starting from one and ascending.

To convert your block to a list, click on the list icon. By default this will create an unordered list, but you can switch to an ordered list by clicking the alternative list icon in the Formatting Toolbar.

Editing lists

After clicking on the list icon any text already present in the block will be converted to the first item in the list, whereas if there is no content in the block only the first bulletpoint or number will be added, ready for your text. To add more items to the list, simply press enter when the cursor is active in the block; this will create a new item underneath the existing one. To delete a item, you can use the backspace key as normal; once you reach the beginning of the line it will remove the current bulletpoint or number.


The fifth icon in the Insert Bar, which looks like a quotation mark, converts your block to a Quotation. This block adds styling to highlight the text as a quote, and also adds an additional field where you can place the Quote Author. Note that the exact styling of the block will differ depending on the theme that you are using.

Quotation block

After clicking the quotation icon, you will see two fields; Quote Text and Quote Author. As you'd expect, the quote content itself should be added to the Quote Text field, and the attribution name in the Quote Author field. 

The Quote Text field is required; until some text is entered the block will not be converted to content. However, the Quote Author field is optional, so you can safely add quotations direct from the article for visibility without attributing it to yourself!

Displaying Code

The sixth icon in the Insert Bar, which looks like a pair of curly braces, converts your block into code; this is useful for users that want to include code examples in their posts. Clicking on the icon will change the block to display a Code Editor:

The code editor

Inserting content into this editor is the same as when you are adding normal text. However, pressing enter in the code editor will not create a new block, instead, it will create a new line in the code editor, with each line being numbered for easier reading.

code in the code editor

Converting a code block back into a regular Paragraph block will maintain the formatting of the text, but the styling will be reset to the standard for the theme.

Using HTML

The seventh icon in the Insert Bar, which looks like a less-than and greater-than sign together, is used to convert your text into the pure HTML content. As discussed earlier in The Publii Editors section of this guide, your post content needs to be converted to HTML to be displayed in browsers correctly. By converting your block to HTML, you will be able to directly manipulate and insert your own HTML code; perfect if you need to use a specific tag or formatting that isn't directly usable in the Block Editor.

HTML code in the editor

Inserting a Divider

The eighth icon in the Insert Bar changes the block to contain only a divider which can be used to separate paragraphs that are not directly connected thematically, or to add a aesthetic touch to the page.

Divider typography element

A divider will take up an entire block, and no additional text can be added.

Inserting a Table of Contents

The last icon in the Insert Bar, which looks like a staggered list of dots and dashes, is for inserting a table of contents to your post. A table of contents can be a useful tool to help users find a specific part of your post, especially long-form posts with many sections, or documentation where users will not necessarily need to read the entire post to get what they need.

Generating a table of contents is largely automated in Publii; after clicking on the corresponding icon, a Label field will be added to the block; here you can define the title for your table. The actual table will be generated automatically using the H1-H6 headers in your post, with indents to show subsections.

The Inline Editor

Since the block editor is still at its core a word processor, it includes the standard text formatting options that you would expect, including:

  • Change text to Bold.
  • Change text to Italic.
  • Add Underline to text.
  • Strikethrough text.
  • Inserting links.

These basic functions are provided by an inline editor, which opens automatically whenever a block of text is highlighted, or if you double-click on a word in a block:

Inline editor menu

The first four icons in the toolbar cover the basic formatting settings; starting from the left; adding bolditalicunderlined or strikethrough text. To use these options, use your mouse to highlight the block of text you wish to change, which will automatically display the inline editor. Then, click the appropriate icon to modify the text accordingly. 

 The last icon on the right of the toolbar also provides a basic formatting function; highlighting text. This adds a coloured background to the text to make it stand out from other areas; useful for highlighting important phrases in your content. As before, to add a highlight, just select the block of text that you wish to highlight to bring up the inline editor, then click on the last icon on the right to apply the highlight.

The other two middle options, with a icons that look like a chain and curly braces, respectively, offer slightly different options that simple text formatting. The curly braces are for changing the text to resemble the Code styling as with the Insert Bar function detailed above; however, if differs slightly in that only the highlighted content will be converted to code, rather than the entire block. The chain icon is for inserting links; let's look at that now:

The chain icon in the inline editor allows for your text to be converted to a link, so that users may click on it to be taken to a different part of your site, to an external site, or to a specific file. To insert a link, select the text that you want to convert to a link in your text, then click on the insert link icon in the inline editor. The Insert Link overlay will appear:

Insert link overlay

In the overlay, the tabs at the top allow you to choose what type of resource you want to link to, while the field in the centre allows you to select the resource. The available link types are:

  • Post - This option creates a link to a specific post on your Publii site. After selecting this option, you can click on the drop-down list in the centre of the overlay to select a post. If you have a lot of posts, you can start typing to dynamically filter the list.
  • Tag - This option links to a specific tag page on your Publii site, showing a list of posts attached to the tag. As with the post, you can select which tag page to link to in the drop-down list, or type to filter the results.
  • Author - Just like the tag and post options, this option lets you link to an author page on your Publii site, showing a list of posts created by the specified author. Select which author you want to link to in the drop-down list.
  • Custom - This option is for links that go to a URL that is most often external to your Publii site. If this option is selected, you should add the complete URL you wish to link to in the field in the centre of the overlay e.g. Also helpful for anchor links that take you to a specific place on the page.
  • File - This option creates a link that allows users to view or download a file that is included in the website files of your site, for example a .pdf or other text document, a media file, or other content that is not readily displayable on a webpage. If this option is selected, clicking on the field in the centre of the overlay will let you choose a file from the Publii File Manager; as with the other options, you can type to filter the visible results.

Once you have chosen a link type and set the target, you'll need to set the Attributes of the link. These are controlled via the toggle buttons underneath the address field in the overlay, with the following options available (simply toggle on the attributes you wish to use):

  • Open in new tab - Enabling this attribute will force the browser to open the link in a new tab, rather than directing the currently-selected tab away from your site to the linked URL.
  • Add "download" attribute - This attribute is only available when adding a File link, and forces users to download the file rather than viewing it in their browser.
  • Add rel="nofollow" - This attribute tells search engines not to follow the link when indexing your site; it can be useful for SEO purposes.
  • rel="sponsored" - This attribute marks the link as a 'sponsored' link i.e. it tells search engines that the link was paid for by an advertiser, or includes some kind of benefit for your site, so it should not be followed as part of your site content.
  • rel="ugc" - This attribute marks the link as "user-generated content", suggesting that the link was not created by the site owner, but was instead posted by another user, such as in a comment or other user-generated content. This again is used by search engine robots to decide whether to follow the link when indexing your site.

If your link information is completed and your attributes set, then you can click on the Save option to finish creating the link.

Removing Links

To remove a link that you have created, double-click on the link in the post editor, or highlight the block of text to open the inline editor. You'll notice that there is a new icon available next to the insert link icon, displaying a broken chain. This is the remove link option, so click on that, and the text will be returned to normal.

The Conversion and Formatting Toolbars

As discussed earlier in this guide, clicking the Ellipses icon to the right of the selected block will display two additional toolbars for modifying your content on the fly, unlike the Insert Bar which may only be used when the block is empty. The Conversion Toolbar is located at the top-left of the block after opening the options, along with the text 'convert to', and the Formatting Toolbar will be on the top-right of the block, providing controls for formatting text and other block-specific functions. 

Block editor toolbar - formating

Since some of the functions here are duplicated from the Insert Bar you may already be familiar with many of the functions in these toolbars, but for the sake of clarity we will cover each function in full.

The available options in these toolbars, from left to right, are:

Conversion Toolbar

  • Convert the block to a Header
  • Convert the block to a Quotation
  • Convert the block to a List
  • Convert the block to Code
  • Convert the block to HTML

Formatting Toolbar

  • Align Text to the left
  • Align Text to the centre
  • Align Text to the right
  • Remove Formatting from the block
  • Additional Settings
  • Delete Block

Let's look more closely at formatting functions:

Aligning Text

If you are using the standard paragraph style for your block, the first three icons in this section are for aligning your text on the page. To align text to the left (default), centre or the right, click on the respective icon in the toolbar.

alignment options

Removing Formatting

The next icon in the Formatting Toolbar, which looks like an eraser, will remove all applied text formatting in the block, such as bold, underline or strikethrough text. It will not change the block type e.g. if you've formatted your content as code, it will not convert it back to a standard paragraph. To change your block back to a standard paragraph, you can click the Paragraph icon that appears as the first icon in the Conversion Toolbar if the block is not set as a paragraph.

Removing formating

Additional Settings

The fifth icon in the Formatting Toolbar, which looks like a gear, open the Additional Settings pop-up. Here, you can apply theme-specific formatting to your text content, as well as add CSS Classes and IDs to your block. 

Additional Settings
Advanced block options

The settings available in this section include a CSS Class and ID field, where you can enter a specific class or ID to add your own styling to the block. The centre option in this section, Paragraph Style, allows you to modify the block with a selection of theme-specific typography options to indicate the type of content. Though these options can change depending on the theme, generally in Publii-native themes you will find the following options:

  • Info - Styles the block to an info box.
  • Highlight - Highlights the block to draw attention to the contents.
  • Success - A lighter highlight to indicate beneficial content.
  • Warning - Usually red-coloured to indicate a potential issue or things to be careful of.

Delete Block

The last icon in the Formatting Toolbar, which looks like a bin, is for deleting the block entirely. To ensure that blocks are not deleted accidentally you will need to click on this icon twice to confirm deletion.

Delete block

Moving and Duplicating Blocks

One of the benefits of the block editor is that it allows you to reorder the blocks, mobing them up or down on the page to get your layout just right. To reorder blocks, first click on the Ellipses icon to open the toolbars. Then, click on the up and down arrows to the right of the block to move the block up or down in the hierarchy.

movement arrows

To reorder all blocks at the same time, after opening the toolbars, click on the Settings icon that appears at the bottom of the editor window:

Settings button at the bottom of the editor window

Clicking this icon will switch to the Ordering Mode; each of the blocks in your article will display the up and down arrows to their right so that you can immediately reorder content. You may also Duplicate a block by clicking the block icon to the left of the block you wish to duplicate. Finally, you may delete a block by clicking the Trash icon to the left of the block you wish to delete; in this mode, only one click is needed to confirm deletion.
