I have 2 divs: one on the left side and one on the right side of my page. The one in the left side has fixed width and I want the one of the right side to fill the remaining space.
#search {
width: 160px;
height: 25px;
float: left;
background-color: #ffffff;
}
#navigation {
width: 780px;
float: left;
background-color: #A53030;
}
<div id="search">Text</div>
<div id="navigation">Navigation</div>
