Problem with CSS3

[Evgeny Bogdanov]

Hi

we have some problems with the CSS3 in our widgets on Shindig-2.5.0.
For example, we use the following code in CSS files:

/* FONT AWESOME CORE
 * -------------------------- */
[class^="icon-"],
[class*=" icon-"] {
  font-family: FontAwesome;
  font-weight: normal;
  font-style: normal;
  text-decoration: inherit;
  -webkit-font-smoothing: antialiased;
  *margin-right: .3em;
}
[class^="icon-"]:before,
[class*=" icon-"]:before {
  text-decoration: inherit;
  display: inline-block;
  speak: none;
}

However, these lines are removed by shindig from css files that gadget uses.
How can I tell shindig not to remove them?

Thank you in advance,
Evgeny
