I've read lots of articles that condemn the excessive use of divs. I have a feeling that I might be doing that in the following mark up:

HTML:

<div id="header">
    <div class="container">
        <div id="banner">
            <h1><a href="http://widerdesign.co.nr/">wider design</a></h1>
            <ul id="lang">
                <li><a href="index.php">English</a></li>
                <li><a href="es/index.php">Español</a></li>
                <li><a href="tw/index.php">??(??)</a></li>
                <li><a href="cn/index.php">??(??)</a></li>
            </ul>
        </div>
        <div id="intro">
            <div id="tagline">
                <h2>Nulla vitae tortor mauris</h2>
                <p>Pellentesque faucibus est eu tellus varius in susc...</p>
            </div>
            <div id="about">
                <h2>right</h2>
                <p>Pellentesque faucibus est eu tellus varius in susc...</p>
            </div>
        </div><!-- #intro -->
    </div><!-- .container -->
</div><!-- #header -->

CSS:

.container {
    margin: 0 auto;
    overflow: hidden;
    width: 960px;
}

/* header */
#header {
    background: #EEE;
}
#header h1 {
    float: left;
}
#header h2, #header a, #header p {
    color: #999;
}
#header h1 a {
    background: url(../images/logo.png) no-repeat scroll 0 0;
    float: left;
    height: 30px;
    text-indent: -9999px;
    width: 500px;
}
#banner {
    border-bottom: 1px solid #DDD;
    padding: 0 0 15px 0;
    margin: 30px 0 30px 0;
    overflow: hidden;
    width: 960px;
}
#lang {
    float: right;
    padding: 9px 0 0 0;
}
#lang li {
    float: left;
    margin: 0 0 0 20px;
}
#lang li a {
    font-size: 10px;
}

/* intro */
#intro {
    overflow: hidden;
    padding: 0 0 30px 0;
}
#tagline {
    float: left;
    margin: 0 40px 0 0;
    width: 540px; /* 560 */
}
#tagline h2 {
    font-size: 24px;
}
#about {
    float: right;
    width: 380px;
}

Explanation of the use of those divs:

header: Defines the background color which expands until the end of the window (lies outside of the div .container).

container: centers the content (but not the background).

banner: to define the background or border color around ul#lang and h1.

intro: same as above but for #tagline and #about (otherwise I have to define say padding or margin for tagline and about individually).

Am I overusing divs?

Can this be simplified?
