I am a beginner but have spent a lot of time in trying to figure this out and to no avail.
Using the developer tool in Chrome I have tried to find a particular class that's unique to the posts that show as previews in the homepage of a new WP site I am creating. But all of them are also applied to the main post that arrives when you click the link to the post.
So, what's the solution?
I want to make the home page links look most like featured posts that many sites have with a rectangular shape, with the posts main image as background or something.
