Question

I’d like to make a webpage like this:

|----------------------------|
|            header          |
|----------------------------|
|  L  |                      |
|  e  |                      |
|  f  |                      |
|  t  |                      |
|     |                      |
|  S  |   Content Area       |
|  i  |                      |
|  d  |                      |
|  e  |                      |
|  b  |                      |
|  a  |                      |
|  r  |                      |
|----------------------------|

The header has a fixed height but it’s width should be dynamic. The left-sidebar should have a fixed width but a dynamic height. For the content area, both height and width are dynamic. When user scale their browser, the scrolling bar should not appear(not set overflow:hidden; to hide it.).

I tried to write code like this:

<div class="top">
    TOP
</div>
<div class="left">
    LEFT
</div>
<div class="main">
    MAIN
</div>

with CSS:

.top {
    width: 100%;
    height: 92px;
}
.left {
    width: 178px;
    height: 100%;
    float:left;
}
.main {
    float: left;
    height: 100%;
    width: 100%;
 }

But it failed.

EDIT: Content Area and Left-SideBar must fill the whole browser window…..
I don’t need

|----------------------------|
|            header          |
|----------------------------|
|  L  |                      |
|  e  |                      |
|  f  |                      |
|  t  |                      |
|     |                      |
|  S  |   Content Area       |
|  i  |                      |
|  d  |----------------------|
|  e  |
|  b  |
|  a  |
|  r  |
|-----|
