Bullet indentation in Garland style.css

From a CSS amateur:

I have text showing in nodes and in added blocks that makes use of bullets. Especially in blocks, width is limited; I'd like the bullet items lined up all the way to the left, to prevent lines breaking. But Garland gives me some serious bullet indentation.

Scanning style.css, I can't find the appropriate control. I chased down some ideas in CSS resources, and added this to the beginning of style.css:

ul {
list-style-type: none;
margin-left:0px;
padding-left: 0px;
}

...to no effect. I figured that some later control must be creating the indentation – but interestingly, when I add the above to the beginning of the CSS, and erase *everything afterward* (then save style.css, refresh browser, etc.), there's still no change.

Does anyone know where to control text bullet indentation in Garland's CSS?
