How To Set Background to Transparent or Non-transparent?

If you want to set the background of a block element to be transparent or non-transparent, you can use the background-color style property as shown below:

  • {background-color: transparent} - Sets background to be transparent.
  • {background-color: #ddddff} - Sets background to be non-transparent with a light blue color.

The following tutorial exercise shows you a comparison of transparent and non-transparent backgrounds:

<html><head>
<style type="text/css">
  H1 {font-size: 20px}
  DIV.page {width: 450px; border: 1px solid black}
  TABLE#out {background-color: #ffdddd}
  TD#box {border: 1px solid black}
  P#one {width: 180px; height: 300px; 
    margin: 10px 10px 10px 10px;
    background-color: transparent}
  P#two {width: 180px; height: 300px; 
    margin: 10px 10px 10px 10px;
    background-color: #ddddff}
</style>
</head><body><div class="page">
<H1>Transparent and Non-transparent Backgrounds</H1>
<table id=out><tr>
<td id=box><p id=one>
