Answer 1

Its not very hard to create a layout like this.

I created one for you, see that Working Fiddle

HTML:

<div class="Container">
    <div class="Header">
        <p>The Header div height is not fixed (But he can be if you want it to)</p>
        <p>This Layout has been tested on: IE10, IE9, IE8, FireFox, Chrome, Safari, Opera. using Pure CSS 2.1 only</p>
    </div>
    <div class="Content">
        <div class="Wrapper">
            <div class="RightContent">
                <p>You can fix the width of this content.</p>
                <p>if you wont, his width will stretch just as it needs to.</p>
            </div>
            <div class="LeftContent">
                <p>this will scroll</p>
            </div>
        </div>
    </div>
</div>

CSS:

*
{
    margin: 0;
    padding: 0;
}

html, body, .Container
{
    height: 100%;
}

    .Container:before
    {
        content: '';
        height: 100%;
        float: left;
    }

.Header
{
    margin-bottom: 10px;
    background-color: #6ea364;
}
.Content
{
    position: relative;
    z-index: 1;
}
    .Content:after
    {
        content: '';
        clear: both;
        display: block;
    }

.Wrapper
{
    position: absolute;
    width: 100%;
    height: 100%;
}
    .Wrapper > div
    {
        height: 100%;
    }

.LeftContent
{
    background-color: purple;
    overflow: auto;
}

.RightContent
{
    background-color: orange;
    float: right;
    margin-left: 10px;
}

Bonus: with a little change in the CSS, you can create a beautiful scrolling. See that Fiddle

Edit: If you want to set a width value to the left side, that is actually bigger then the body size (and to have an horizontal scroll), do it that way.

<div class="LeftContent">
    <div style="width:1200px;"> <-- better to aplly the width from the CSS
        ..<The content>..
    </div>
</div>

Answer 2

Have you tried

overflow-y: scroll;

in body?

Answer 3

you need to add overflow:auto; to the area you want to scroll.
