Position Fixed width 100%

Question

I have a position:fixed left column at 250px wide with 100% height and I\'m trying to place a fixed, fluid horizontal bar at the top but to the right of the lef

Answer 1

Instead of using left: 250px use padding-left:250px in conjuction with box-sizing: border-box:

.top-bar {
    position:fixed;
    top:0;
    left:0;
    width:100%;
    height:54px;
    background:#090909;
    z-index:1000;
    padding-left: 250px;
    -moz-box-sizing: border-box:
    box-sizing: border-box:
}
