Site Logo Block
The Site Logo Block allows you to add or update the logo for your site. Although you can add this block into your normal Page or Post content, it will be more useful once you can edit your Theme’s templates.
Once you've added the block, there are further options available in the Settings Sidebar including an option to change the style, modify the image width, and automatically add a homepage link. You can also adjust the image width using the blue circle ‘handles’ that appear on the logo once it’s selected.
