Wikitext makes it pretty easy to style lists. But styling them within portable infoboxes might be less familiar to you.
Styling bulleted lists
Generating bulleted lists is a breeze in wikitext. You know the drill:
*Vulcans ** Spock *** T'Pring ** Tuvok *** T'Pel ** T'Pol *** Kos
But how do you style that within a portable infobox? Well you could just accept the default. But the chances are that by the time you got to the spouses of the more famous Vulcans in this list — especially if this were in a horizontal list — you'd get some funky indentation.
So consider some general styling for unordered lists, like this:
.portable-infobox .pi-data-value ul { text-indent:-1em; padding-left:1.5em; padding-top:.25em }
If you're trying to better place an unordered list within a horizontal group, you may find that you'll need to add something like this, just to keep things even more tightly controlled:
.pi-horizontal-group .pi-horizontal-group-item { text-align:left!important; padding:2px 5px 5px 5px!important }
Obviously, those aren't the only values that'll work, but they're a good place to start.
Styling lists created with wikitext colons
Some communities don't create traditional unordered lists. Sometimes, lists are created through colons, like this:
Vulcans :Spock<br/>Tuvok<br/>T'Pol
In ordinary wikitext, this would generate some horizontal separation between Vulcans and the list of Vulcans. But in PI code, you've got to specify that space — and you've got to !important it. Let's say, just for fun, that you only wanted it to apply to a theme called "species". You'd have to do this:
.pi-theme-species dl { margin:1em 0!important; }
Oh, and dig this: while you can change the margins, the values above are what naturally occur in default wikitext.
