Question

I’m playing around with twitter bootstrap and I noticed this css definition, which I can’t seem to override with my own css definitions. What is it and what does it mean:

[class*="span"] {
  margin-left: 20px;
}

I tried a google search and nothing came up – maybe it is disallowing search characters or something

Answer 1

It’s an attribute selector.

[class*="span"] selects elements with a class attribute that contains span:

<div class="in-spanish">Test</div>
               ^^^^
