Picking this back up after we’ve made some changes.
First observation, it’s not possible to preview a different layout for categories as far as I can tell. We wanted to change the way the categories appeared from using Boxes with Featured Topics to Categories with Featured Topics. Updating this setting changed the live site. Just sharing here for others benefit.
New question, if possible, how can we edit the color of these links and text? We find it visually confusing on what’s a link and what’s not and there are so many links here. We’d like to customize the color of certain links to help people focus on what they actually need or may want to click on to further explore.
