 Tips
 ----
 Make sure your server is setting a valid **last-modified** header for its CSS responses. Livecss detects new CSS by frequently making a HEAD request to the URLs referenced in the <link> tags on the page, and it reloads the files which have a recent last-modified header. If your last-modified header is blank or always set to "now", the CSS will continuously reload, once per second. This will put extra load on the browser.
