We have a few types of boxes that can be added to the site. These would typically be added within a column layout. (Columns are a standard Gutenberg layout block)
|Download Box||Grid Box||Photo Link Box|
Generally if you’re adding more than one box you would start by adding a column block, then you would add the desired box into each column.
When a box is selected in the Block Editor, you’ll see a series of custom fields in the right sidebar of the editing screen. These are the properties of the box being added. It typically includes a title, body, link and/or image. When you made edits in these fields, the preview of the box should update in real time.
Note: If the sidebar editing fields are not visible, you may need to click on the gear icon in the upper left corner of the screen.
