The Custom HTML block allows you to add HTML code to a post or page.
Here’s what it looks like when it’s added to the Block Editor.
To add a cover block to a page you click on the + icon at the left of any empty block or at the top left of the editor then search for HTML, or locate it in the Formatting section, and click on the Custom HTML icon.
More detailed instructions for adding blocks can be found here.
Add HTML Code
Once you have added the Custom HTML block, you can add your code.
Click on Preview to view your code directly inside the block.
Some HTML tags like script, iframe, form, input, and style can’t be used on free Edublogs blogs.
