I work in front end and set CSS background using the shorthand notation very often. I was wondering for a div with a background image whose parent div has a white background – should the child have background-color white or transparent ? Which is better for performance?

ie:

<div id='parent' style='background:white;'>
    <div id='child' style='background:WHITE image no-repeat center center;'></div>
</div>

OR

<div id='parent' style='background:white;'>
    <div id='child' style='background:TRANSPARENT image no-repeat center center;'></div>
</div>

    Simply don’t set the background color in the shorthand declaration. You can skip it.
    Saves on bandwidth, and css-browser-rendering-performance is kind of totally Dependant on the users/visitors browser!

    Good luck!
