For the grid instead of the slider, try this plugin to create the grid:
https://wordpress.org/plugins/grid-columns/
Read the FAQ tab, it has the instructions.
The ide is would would put each feature advertiser logo within its own block in the grid. That way there are all shown.
I can not think of any examples off the top of my head where a user is using CSS to highlight an entry. But here’s an example:
#cn-list .food-franchises {
background-color: yellow;
}
That would turn the background of all entries that are categorized as Food Franchises to yellow. So, it you had a Featured Advertiser category, you could do this:
cn-list .featured-advertiser {
background-color: yellow;
}
Of course you would use a nicer color, prolly something more subtle but still noticeable.
Adding a “badge” would be very similar, you would be adding a background image (the badge) which it position could be offset so it doesn’t cover up any of the entry info.
The new category widget coming in Widget Pack 2.0 is just like the one you have not but with many more configuration options. For example, you would have one widget configured to show just like you have it now. But you could add a second widget and configure it to show only the entries in the Featured Advertisers category with their logo.
The Custom Category Order extension would simply let you make sure the Featured Advertisers category is at the top of the category list (that you already have in your sidebar) rather down with the other categories that begin with “F”.
Hope that helps. Any way, just something to think about if you want to try to make them more prominent.
