Html div width 100% not functioning

Question

There are some problems with my HTML, so I am posting the code.

The first tag is a div with id=\"header\". I have given it 100% width and g

Answer 1

This is the style sheet which works with me:

  body{    
    margin:0;    
    padding:0;
}  
    .clear{    
    display:block;   
    clear:both;
}    
    #header{   
    min-height:156px;  
    display: block;
    width:100%;
    background-image:url('http://www.webdesignideas.org/images/bellevueBg.gif');
}
    #head-contents{    
    width:974px;    
    margin-left:200px;
    height:156px;
}
    #header ul {    
    margin:85px 23px 0 0;    
    float:right;
    list-style-type:none;
}
    #header ul li {    
    display:inline;
}    
    #header ul li a {   
    margin-left:46px;
    font-size:19px;
    color:#fff;
    text-decoration:none;
}

    #header ul li a:hover ,    
    #header ul li a.active {    
    color:#FD7600;
}

Resizing the window and setting the margins to auto will screw the position of your inner div because it s width doesn t fit the window.

#header {   
    min-height:156px;
    width:100%;
    background-image:url('http://www.webdesignideas.org/images/bellevueBg.gif');
}

Answer 3

I have found the solution:

#header {
  height: 156px;
  min-width: 990px;
  background-image: url('http://www.webdesignideas.org/images/bellevueBg.gif');
  display: block;
}

#head-contents {
  width: 974px;
  margin: 0 auto;
  height: 156px;
}

It's all a matter of min-width in the #header. I checked out facebook's login page and figured it out.

Answer 4

Take out the background-image property from #header and apply this style to the body tag:

background: url('http://www.webdesignideas.org/images/bellevueBg.gif') 0 0 repeat-x #fff;

You will no longer have the problem you described. All you need to do now is cut down the background image to 156px height, using an image-editing software package like Photoshop.

Working FIDDLE Demo

You must set the width of your head-contents as the min-width of your header:

#header {
    min-height:156px;  
    display: block;
    width:100%;
    background-image:url('http://www.webdesignideas.org/images/bellevueBg.gif');

    min-width: 974px; /* this is width of head-contents */
}
