Before, all **[this](http://www.habeshajobs.com/liip.php)** is my page, and I was in the middle of creating a layout, using css `@media` query, for detecting and adjusting the page, depending on the pixel of the browser.... 

All was going fine, but if you see:

```
<div id='x'>
    <h1>I am content </h1>
    <h1>I am content </h1>
    <h1>I am content </h1>
    <h1>I am content </h1>
    <h1>I am content </h1>
    <h1>I am content </h1>
    <h1>I am content </h1>
</div>

```

You will notice, it has overflown of the parent `div` which is `<div id='sep'></div>` ONLY, when viewed from desktop. 

You can check the source code of the page, or here is the full code:

```
<html>
<head><style>
body{margin:0px; padding:0px;}
#a{height:150px; background-color:#ffffff; border-bottom:1px solid #CCC;}
#x{min-height:350px; margin-top: 10px; background-color:#CCC;}
#y{min-height:30px; margin-top: 10px; background-color:#CCC;}

@media all and (min-width:700px){

#b{width:100%;  min-height:400px;}
    #sep{width:960px; margin:auto;}
    #x{width:65%; float:left;}
    #y{width:32%; float:right; }
#c{background-color:#656565; height:80px;}
.for-mob{display:none;}
.for-desc{background-color:green;}
}
@media all and (max-width:700px){
.for-mob{background-color:green;}
.for-desc{display:none;}
#b{width:100%; min-height:400px; }
#x{width:100%; display:block; }
#y{width:100%; display:block; }
#c{background-color:#656565; height:100px;}

}
</style></head>
