I'm currently using Apart Night as a theme on
my forums. The width is currently fixed, and I wanted to know if it'd be possible to make it fluid; if so, how?
Your forum is already fluid, if only has a set max width so it doesn't look too much on huge displays. But if you don't care about that you look on your global.css and search for
.wrapper {
width: 85%;
min-width: 970px;
max-width: 1500px;
margin: auto auto;
Take off the max-width.
