Fluid width of center column

Question

I have 3 column layout. I am trying to make the center column with fluid width and the left and right column with fixed width 200px. it looks fine on my screen but when i resize browser window then right column fell down on smaller window size.

CSS :

#content {
    float: left;
    width: 66.8%;
}
#sidebar-left {
    float: left;
    margin-right: 24px;
    width: 200px;
}
#sidebar-right {
    float: right;
    width: 200px;
}

Answer 1

You don't really need jQuery for this purpose. You can leverage your layout by using plain old css. The flexible box model would fit this scenario perfectly but I wouldn't suggest it due to the lack of browser support currently. I'd suggest placing your boxes in a wrapper with display:table and giving the child boxes a display:table-cell

<div id="wrapper">
    <div class="sidebar left fluid"></div>
    <div class="content fluid"></div>
    <div class="sidebar right fluid"></div>
</div>

And then to display all boxes inside the wrapper element side by side, you can use the following css...

#wrapper{display:table}
div{height:300px; display:table-cell}
div.content       {  width:100% }
div.sidebar  { width:200px }
.left { float:left }
.right { float:right }
.fluid{display:inline-block}

Here's a JSFiddler Example where I coloured the boxes so you can easily distinguish them

A simple option for this sort of layout would be to go the display: table route:

.wrap {
    display: table; 
    margin: 0 auto;
}

.wrap > div {
    display: table-cell; 
    height: 200px; 
    background: green;
    width: 66%;
}

#sidebar-left, #sidebar-right {
    width: 200px; 
    background: red;
}

Answer 3

I have sort it with this way.

<div id="wrap">
<div id="sidebar-left"></div>
<div id="sidebar-right"></div>
<div id="content">
<div class="inner"></div>
</div>
</div>

#wrap { overflow:hidden; }
#content {
    padding: 0 200px;
    margin: 0 auto;
}
#content .inner {
    width: 98%;
    margin: 0 auto;
}
#sidebar-left {
    float: left;
    width: 200px
}
#sidebar-right {
    float: right;
    width: 200px
}
