文本输入元素内的字体令人敬畏的图标

Question

.wrapper input[type="text"] {
    position: relative;
}

.wrapper input[type="text"]:before {
    font-family: 'FontAwesome';
    position: absolute;
    top: 0px;
    left: -5px;
    content: "\f007";
}

我在默认的font awesome css中声明了字体面，所以我不确定上面添加字体族是否是正确的方法。

 @font-face {
     font-family: 'FontAwesome';
     src: url('../Font/fontawesome-webfont.eot?v=3.2.1');
     src: url('../Font/fontawesome-webfont.eot?#iefix&v=3.2.1') format('embedded-opentype'), url('../Font/fontawesome-webfont.woff?v=3.2.1') format('woff'), url('../Font/fontawesome-webfont.ttf?v=3.2.1') format('truetype'), url('../Font/fontawesome-webfont.svg#fontawesomeregular?v=3.2.1') format('svg');
 }
