How can we make the multicolumn filling the entire page, and have the column link label on the image like the following?
We use the Dawn theme, and the reference image store uses Dawn as well, so it has to be possible somehow.
Not everyone has the same setup as you.
When seeking help don’t just post images , ALWAYS provide a link to a publicly accessible inspectable urls of what you have and what is being referenced.
From an image it’s not clear what the reference store has done it may not even be the multicolumn section in the image.
Use a custom css setting to make the columns to ~49% width each, or 1/2 the row if CSS grid row or flex.
