Spacer block

If you want to have a space between two blocks, the spacer block is what you will use.
A vertical spacer adds space between blocks in a column (as in a page or post).
A horizontal spacer adds space between blocks in a row (as in a Navigation block).

(Note: Using a Navigation block requires a block theme or a theme that has support for template editing.)

In this video, you can see how you can use the spacer block and the different settings to modify it.

To add an spacer block, click on the Add Block icon.

You can also type /spacer and hit enter in a new paragraph block to add one quickly.

Block toolbar

In order to reveal the block toolbar, you can click on the block and the toolbar will display.

Every block comes with unique toolbar icons and blocks specific user controls that allow you to manipulate the block right in the editor.

The Spacer block shows four buttons in the block toolbar:

• Transform to
• Drag icon
• Move arrows
• More options

Transform to:

When you click on the “Transform” button, you can convert the Spacer block into Columns, Separator, Details, or Group blocks.

• Separator: Changes the Spacer into a visual horizontal line that helps divide content, providing a cleaner visual break between sections.
• Group: Allows you to wrap the Spacer inside a Group, enabling background color, padding, margin, and border customization for better layout styling.
• Columns: Useful if you want to place multiple blocks side-by-side; this transformation helps shift the layout into a multi-column structure.
• Details: Converts the Spacer into a collapsible content block, allowing additional context or content to be toggled by the user.

Drag icon:

To drag and drop the block to a new location on the page template, click and hold the rectangle of dots, then drag to the new location. The blue separator line indicates where the block will be placed. Release the left mouse button when you find the new location to place the block.

Move arrows:

The up and down arrow icons can be used to move a block up and down in your document.

More options

These controls give you the option to copy, duplicate, and edit your block as HTML.

Read about these and other settings.

Block settings

Every block has specific options in the editor sidebar in addition to the options found in the block toolbar. If you do not see the sidebar, simply click the ‘cog’ icon next to the Publish button.

Spacer settings

The Height setting adjusts the height of the space. The Width setting adjusts the width of the space. You can adjust the settings by either:

• Typing the number in the “Spacer Settings” box, or
• Dragging the handle at the bottom of the spacer (for the vertical spacer) or at the side of the spacer (for the horizontal spacer).

You can also change the unit by clicking on PX to display a dropdown with the other supported units- PX, %, EM, REM, VW, and VH.

When Spacer is a child of a flex layout block (Row, Stack, Navigation) custom size controls are removed and flex child controls added instead.

Dimensions

The paragraph provides dimension settings options to add padding and margin. For details refer to this support article:

Advanced

The “Advanced” tab lets you add HTML anchor and CSS class(es) to your block.

“HTML anchor” allows you to make a unique web address for a particular “Shortcode” block. Then, you’ll be able to link directly to a “Shortcode” block of your page.

The “Additional CSS class(es)” lets you add CSS class(es) to your block, allowing you to write custom CSS and style the block as you see fit.
