If a block element is nested in another block element, the inner block, child block, will be formatted as the content box of the outer block, parent block. The HTML and CSS document below shows you how nested block elements are formatted:

<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: 230px; height: 230px;
    margin: 30px 10px 40px 20px; 
    border: thin solid red;
    padding: 30px 10px 40px 20px; 
    background-color: #ddffdd}
  P#child {width: 200px; height: 200px; 
    border: thin solid blue;
    padding: 30px 10px 40px 20px; 
    font-size: 14px; 
    background-color: #ffffff}
  TD.legend#w30 {height: 32px; background-color: #ffffff}
  TD.legend#g30 {height: 32px; background-color: #dddddd}
