RSS XML Tutorial: CSS File

If you want your news feed file to be readable in older browsers which don't recognize RSS files you can attach a CSS style sheet to your XML file. The CSS file will be parsed in older browsers, but not in modern browsers or news feed readers.

Note: The last browsers to need this technology were Internet Explorer 6, Firefox 1 and Safari 1

Link to CSS File

Use the following syntax within your RSS file to specify a link to a style sheet. The next section will explain how to build the stylesheet.

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/css" href="psurss.css"?>

<rss version="2.0">

</rss>

The CSS Specifications

In the CSS file, you would define styles for each tag (e.g. channel, item, link), much as you do in a CSS file for an HTML document.

Some Tips

  • Use display:block if you want the tag to act like a P or H1 tag.
  • Use display:inline if you want the tag to act like B or I.
  • Define the rss tag much as you would an HTML body tag.
  • For item level tags, use the specifications like item link (for the link tag), then define formatting. Otherwise, they may be confused with the channel level tags.
  • Use display:hidden to suppress tags you don’t want displayed.
  • Use font-pixel sizes instead of relative sizes (trust me)
