How To Set Page Widths to Relative Length Units? - CSS Tutorials - Page Layout and Background Image Design

Knowing that setting page widths to absolute length units will cause problems on images with different browser resolutions, you can set your page width to a relative length unit, like px (pixel). The tutorial exercise code below sets a page width to 730 pixels:

<html><head>
<style type="text/css">
  BODY {background-color: gray}
  DIV.page {background-color: white; width: 730px;
    padding: 25px; text-align: left}
  HR {width: 730px}
  P {width: 730px}
</style>
</head><body><center><div class="page">
<p>
<img src=fyi_banner_blended.jpg width=728 width=90>
</p>
<H1>730-Pixel Wide with an Image</H1>
<hr align=left>
<p><script language="JavaScript">
  for (i=0; i<100; i++) {
    for (j=0; j<10; j++) {
      document.write(j+' ');
    }
  }
</script></p>
<p align="right">By FYICenter.com</p>
</div></center></body></html>

Save the code in 730PixelPageLayout.html and view it with FireFox and IE on a 1280x1024 screen, you will see the page displayed nicely in both browsers:
