[css] Change font-weight of FontAwesome icons?

I'd like to make one of the FontAwesome icons a bit less heavy - it's much heavier than the font I am using. This how it looks presently:

:

Ugly, right? So I've tried resetting the font-weight as follows:

.tag .icon-remove  { 
  font-weight: 100;
}

The attribute appears to be set correctly in the CSS, but it has no effect - the icon looks just as heavy as before. I've also tried font-weight: lighter and -webkit-text-stroke-width: 1px with no effect.

Is there any way I can make the icon less heavy? The docs say "Anything you can do with CSS font styles, you can do with Font Awesome" but I can't figure out how to do this.

.star-light::after {
    content: "\f005";
    font-family: "FontAwesome";
    font-size: 3.2rem;
    color: #fff;
    font-weight: 900;
    background-color: red;
}

Webkit browsers support the ability to add "stroke" to fonts. This bit of style makes fonts look thinner (assuming a white background):

-webkit-text-stroke: 2px white;

Example on codepen here: http://codepen.io/mackdoyle/pen/yrgEH Some people are using SVG for a cross-platform "stroke" solution: http://codepen.io/CrocoDillon/pen/dGIsK

The author appears to have taken a freemium approach to the font library and provides Black Tie to give different weights to the Font-Awesome library.

Another solution I've used to create lighter fontawesome icons, similar to the webkit-text-stroke approach but more portable, is to set the color of the icon to the same as the background (or transparent) and use text-shadow to create an outline:

.fa-outline-dark-gray {
    color: #fff;
    text-shadow: -1px -1px 0 #999,
            1px -1px 0 #999,
           -1px 1px 0 #999,
            1px 1px 0 #999;
}

It doesn't work in ie <10, but at least it's not restricted to webkit browsers.

Just to help anyone coming to this page. This is an alternate if you are flexible with using some other icon library.

James is correct that you cannot change the font weight however if you are looking for more modern look for icons then you might consider ionicons

It has both ios and android versions for icons.
