Actually, I wanted to update you. I modified your code slightly, and I’m getting a little closer, but I’m not there yet.
Using this code:
.single-x-portfolio .entry-featured {
width: 100%;
position: relative !important;
float: left;
clear: both;
transform: none !important;
}
Gets me closer. This effects the individual portfolio pages, and not the main portfolio page, which is what I wanted. However, it only effects the positioning of the featured image on the individual portfolio page, which is now centered and apparently displaying at its full width.
The subsequent ‘rows’ still display squished over to the right in a column.
Incidentally, I’m trying to have the Featured image display at the top centered as it currently is, and then build the rest of the individual portfolio pages using Cornerstone to add content.
