Hello, Is there a way to add this type of sidebar in to the theme with SIteOrigin Pagebuilder, or does it need code? I would like to make it look like this where it is a blue box on the right that overlaps the header. If overlapping is too hard then that is only secondary. https://georgeandmatilda.com.au/eyecare/eye-conditions/hyperopia/
Sure, with Page Builder, you can create a two-column design. When editing the row click on the right cell, a new Cell Styles panel will appear, you can set the background color via the Cells Styles panel.
When editing the cell in question you can try setting a negative margin in the Attributes > CSS Styles field, something like:
I can’t say off-hand if that’ll work but you can give it a try and see how it goes.
