So I get asked about these too much, and I only offer them with full css layouts(costing at least 1GB), so I figured I might as well put up one for free. You still have to do the work yourself to get the background colored and such, but I did the CSS work for you ;D

The only rule I have is do no remove my credit note at the bottom. (It's small.)

These only work in dens, clans, and branches! CSS does not work in the forums.

The table it will make looks like the one on my Main Account, the table with "Welcome to the Dark Marsh" at the top.

CSS Needed

Pastebin link.
Copy the code it gives you and paste directly into your den description.

This is with backgrounds. To get without backgrounds, just remove the "background:#HEXCODE;" parts. Or saving without removing them may auto remove them. When I say "without backgrounds" I really mean it will make them match LioDen's CSS or your den CSS if you have any.

You're welcome to rearrange things if you know how.

Oh yeah, and you can just use the expanding boxes ;D
Remove the *s. Remember you still need the CSS code!
The bigger one:
<*div class="tbox1"> TEXT HERE <*/div>
The smaller one:
<*div class="tbox2"> TEXT HERE<*/div>

Add style="background:#HEXCODE;" in there if you want to color it, like any div box.

More Boxes!

By request, here's a rounded corner box similar to my own ^^ Will be doing more of these later.
