This is a live demo of a CSS box with shadows - it should render as expected in most modern browsers while it will display a standard 1px border in older browser.

This is the actual CSS and HTML code that renders the shadowed box - it is written in pure CSS3 and requires no images.

<style>
  #box-with-shadows {
    color: #222222;
    background-color: #f9f9f9;
    border: 1px solid #eee;
    box-shadow: 0 4px 16px rgba(0, 0, 0, 0.2);
    -moz-box-shadow: 0 4px 16px rgba(0, 0, 0, 0.2);
    -webkit-box-shadow: 0 4px 16px rgba(0, 0, 0, 0.2);
    display: block;
    font-family: arial;
    font-size: 10pt;
    width: 80%;
    margin: 20px auto;
    padding: 20px;
    position: relative;
    z-index: 10000;
  }
</style>
