Make Font Awesome icons in a circle?

Question

I am using font awesome on some project but I have some things that I want to do with font awesome icons, I can easily call an icon like this:

Answer 1

I like Dave Everitt's answer with the « line-height » but it only works by specifying the « height » and then we have to add « !important » to line-height ...

.cercle {
    font-size: 2em;
    width: 2em;
    height: 2em;
    text-align: center;
    line-height: 2em!important;
    background: #666;
    color: #fff;
    border-radius: 2em;
}

Answer 2

try this

HTML:

<div class="icon-2x-circle"><i class="fa fa-check fa-2x"></i></div>

CSS:

i {
    width: 30px;
    height: 30px;
}

.icon-2x-circle {
    text-align: center;
    padding: 3px;
    display: inline-block;
    -moz-border-radius: 100px;
    -webkit-border-radius: 100px;
    border-radius: 100px;
    -moz-box-shadow: 0px 0px 2px #888;
    -webkit-box-shadow: 0px 0px 2px #888;
    box-shadow: 0px 0px 2px #888;
}
