I have a parent div and 2 divs inside it. First child div is 50px wide and 100% height. Second child div is 100% height and I it to take rest of the width ( 100% - 50px ) how do I do that?
Here is the fiddle that I've created: http://jsfiddle.net/muGty/
Basically I want blue div (right ) to occupy rest of the grey container completely.
<div class="parent">
<div class="left"></div>
<div class="right"></div>
</div>

Answer 1

Do you mean like this?
<div id="left">
</div>
<div id="right">
</div>
CSS
html, body {
height: 100%;
}
#left {
width:200px;
float:left;
background: #f00;
height: 100%;
}
#right {
margin-left: 200px;
background: #0f0;
height: 100%;
}
Update:
You can also use calc() property in CSS3, which will ease up this process like
html, body {
height: 100%;
}
#left {
width:200px;
float:left;
background: #f00;
height: 100%;
}
#right {
float: left;
background: #0f0;
height: 100%;
width: calc(100% - 200px); /* Negate the fixed width element value from 100% */
}

Answer 2

Just change your right div to this:
.right{
float:left;
height:50px;
width: calc(100% - 50px);
background-color: blue;
display:inline-block;
}

Answer 3

You could add a 50px margin to right and float it.

Answer 4

What about editing your right class to make it look like this :
.right{
float:left;
height:50px;
width: 100%;
margin-right:-50px;
background-color: blue;
display:inline-block;
}

Answer 5

You could also work with an absolute position for the right side column. Consider this example:
.parent{
width:100%;
height:50px;
background:#888;
position:relative
}
.left{
float:left;
height:100%;
width:50px;
background:green
}
.right{
background:red;
position:absolute;
bottom:0;
left:50px;
right:0;
top:0
}
Also see this Fiddle. Note that you would need to set position: relative on the parent container for this to fly.
