using bootstrap glyphicons

I have web forms page.

In my css i'm using a .svg image in background url tag like this:

        label.error {
            background: url('TestImage1.svg') no-repeat;

Instead of using a .svg image I want to use one of these bootstrap glyph icons.

If I want to use the icon called  .glyphicon-asterisk which looks like this

Anyone know how I reference it this background url tag?

 background: url('TestImage1.svg') no-repeat;

You can't.  It's a font that's inserted using the ::before css selector.

in otherwords, you need to add the following classes to your label


<label class="error glyphicon glyphicon-asterisk">

I've been using bootstrap a lot lately and as a work around the only thing I could possibly see working would be to wrap the glyphicon in another item or use something along the lined of a conversion tool and make a copy in the correct image format you currently need for this project.
There are some great tools to create backgrounds and icon images free or to convert images online free and easily.

I forgot to mention that you obviously remove:

background: url('TestImage1.svg') no-repeat;

from label.error {}
