How to scale SVG using CSS

Is possible to scale SVG using CSS? I use <img> to insert an SVG icon in HTML. Here is my code: http://jsfiddle.net/kw5fuw7L/.

nav {
    width: 100%;
    background: #202125;
    box-shadow: 0px 1px 0px 0px #2C2E32;
    padding: 0;
    overflow: hidden;
}

nav ul {
    list-style: none;
    overflow: hidden;
    margin: 0;
    padding: 0;
}

nav ul li {
    float: left;
    position: relative;
    padding: 20px 0;
    width: 120px;
    text-align: center;
}    

nav ul li.active {
    background: #F5A623;
}

svg path {
    fill: #fff !important;
}

nav ul li .svg-container {
    width: 20px;
    height: 10px;
    margin: 0 auto;
    padding: 0 auto;
}

nav ul li img {
    display: block;
    margin: 0 auto;
    padding: 0 auto;
    width: 100%;
}

nav ul li span {
    display: inline-block;
    color: #fff;
    padding-top: 10px;
}

nav ul li a {
    position: absolute;
    top: 0;
    left: 0;
    height: 80px;
    width: 120px;
    text-indent: -5000em;
}

Unfortunately, I have to use this code too: http://jsfiddle.net/praveenscience/wuSF7/, to give them color. It works okay before I put there this script.

I would be grateful if someone have idea how to scale an SVG icons.
