Adding a font awesome icon to a css class

Question

I have a dashboard with different sized widgets. I need to make a single class that adds a border around the widget, and also adds a font awesome icon to the top right of the widget on top of the existing content.

How i do this with one css class?

I am not 100% understand your need but i was try to make something make close of your need.

HTML:

<span class="icon fa-id-card-o"></span>

CSS:

 .icon {
        display: inline-block;
        font: normal normal normal 14px/1 FontAwesome;
        font-size: inherit;
        text-rendering: auto;
        -webkit-font-smoothing: antialiased;
        -moz-osx-font-smoothing: grayscale;
        position: absolute;
        right: 0;
        color: red;
    }
    .icon:before {
        content: "\f2c3";
    }

.icon {
    display: inline-block;
    font: normal normal normal 14px/1 FontAwesome;
    font-size: inherit;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    position: absolute;
    right: 0;
    color: red;
