"What URL are you talking about?" you may be asking. Let me give you an example so you can see more clearly what I mean.
<link rel="stylesheet" type="text/css" href="https://dl.dropbox.com/scl/fi/fug26ca908wzvgukmoump/charred-wood.css?rlkey=klh4xgro1la2u4rrqxecta373&st=gafkv3m1&dl=0" />
Here is the code for the Charred Wood layout. You'll see that in the href attribute there is double quotes surrounding the URL that I have highlighted in green. That highlighted section is exactly the URL I'm talking about. So to find the URL for any of the layouts, look for where it says href and copy whatever is inside the double quotes. Not including the double quotes themselves, just what's inside of them.
All of these layouts are clan compatible (applying works like dens and branches) and any whose names are in green have cave images included.
Disclaimer: These den boxes are subject to the same rules as my other free CSS, so anyone distributing them through free CSS or packaging them with their own commissions without my express permission will be reported for doing so. That is a gross breach of my rules. You can also only use one of these add-ons at a time as they will override each other.
The preview images display how they look with no style changes made. As the name suggests, the first set of boxes become larger when hovered over, but on mobile they are set to be taller with no expansion to make them easier to read. Hover effects can be a bit odd on mobile.
