Question

I recently finished a web version of an old text and I’ve been getting help with my crappy novice-level CSS over at Code Review. The most recent version is here.

But here’s the problem: somehow the changes have broken the original .arg span class definition I had, and it doesn’t seem to help to change it to .arg > span (as I have done) or to change the left margin from 74 to 144. You can see the resulting problem in the browser-rendered page by searching for “Sum of your First Argument” or just going down to ‘pages’ 408–10 by consulting the page numbers in the left-hand margin.

In short, .arg > span doesn’t work, specifically margin: 1 0 0 74; doesn’t seem to do anything, and I can’t figure out why. Any help would be appreciated.

Answer 1

You need units on nonzero values.

margin: 1px 0 0 74px;

0 is the only value for which units are not required. Regardless of the unit (assuming units of finite size, anyway), zero is always zero.
