Display latest posts from categories as an actual list for CSS style. SO close!

Basically, I am going for something similar to gizmodo.com, towards the bottom, with the small images.

It lists the category, image of the first post, then the title of the 3 most recent posts.

I am sure it is a simple fix, but I have been messing with it for a few days.

The ONLY thing I can’t seem to do is get each category to be its own unordered list.

Here is my current progress: https://crowncrazed.com

I have hidden all except the first image with
ul.minors-preview li + li .image {display:none}

Here is the pastebin link to the code in my index.php, but I cannot seen to figure out how to place the closing for each category.

Thanks in advance!
