[Solved] Moving An Absolute Position Element Based Off Of Its Center


I think this is what you are trying to do is to use CSS transforms property with the value translate.

#your-div-id {
    -ms-transform: translate(-50%, 50%); /* IE 9 */
    -webkit-transform: translate(-50%, 50%); /* Safari */
    transform: translate(-50%, 50%);
}

The value -50% controls X-axis, and 50% is for the Y-axis

PS: play around the values to get what you want
