One of the horizontal formatting rules says: if the width of the parent element is specified and greater than the full width of the child stack. the full width of the child stack will be extended match the specified width of the parent element. The HTML and CSS document shows you a good example on this rule:

<html><head>
<style type="text/css">
  H1 {font-size: 20px}
  DIV.page {width: 425px; border: 1px solid black}
  TABLE#out {background-color: #ffdddd}
  TD#box {border: 1px solid black}
  DIV#parent {width: 350px;
    margin: 5px 20px 5px 20px; 
    border: 20px solid #ffbbbb;
    padding: 5px 20px 5px 20px; 
    background-color: #ddffdd}
  P#child {width: 200px;
    margin: 5px 20px 5px 20px; 
    border: 20px solid #bbbbff;
    padding: 5px 20px 5px 20px; 
    font-size: 14px; 
    background-color: #ffffff}
  SPAN#parentWidth {width: 350px}
  SPAN#parentContent {width: 270px}
  SPAN#childWidth {width: 200px}
  SPAN#child {width: 120px}
  SPAN#w20 {width: 20px; background-color: #ffffff}
  SPAN#g20 {width: 20px; background-color: #dddddd}
  SPAN#ext {width: 30px; background-color: #ff0000}
</style>
</head><body><div class="page">
