Question

I am attempting to have an opacity effect on my div which has a background-image applied, and still keep the text “un-opacified”.
My markup:

<div id="projects" class="feature">
    Projects
</div>

My CSS:

.feature {
    display: inline-block;
    margin: 30px;
    cursor: pointer;
    width: 300px;
    height: 300px;
    -webkit-border-radius: 150px;
    -moz-border-radius: 150px;
    border-radius: 150px;
    font-family: 'Droid Sans', Helvetica Neue, sans-serif;
    font-size: 2em;
    color: #fff;
    text-align: center;
    line-height: 1.2em;
}

.feature:after {
    /* Fallback for web browsers that don't support RGBa */
    background-color: rgb(0, 0, 0);
    /* RGBa with 0.6 opacity */
    background-color: rgba(0, 0, 0, 0.8);
    /* For IE 8*/
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#99000000, endColorstr=#99000000)";
}

.feature#projects {
    background-image: url('img/hero.png');
}

I thought of using pseudo elements, but to no avail!

Any ideas?

I might use a semi-transparent png for the background image, then style the text accordingly.

You might also want to look into RGBa:

This applies to background-color, although it may also work on your image (untested, though)
