    Fixit - CSS Import Directive

  • This test determines if your page CSS makes use of the @import directive.

CSS files should be directly referenced in the HTML markup, or condensed into a single file to increase data transfer time.

    Fixit - Image Sprites

  • This test determines if your page make use of image sprites. Grouping multiple images into one image sprite drastically speeds up delivery and load time. When many images are used independently many network requests are required to download them all, an image sprite combines the images into a single file which can then be cut-up using CSS.

    Fixit - Favicon

  • This test determines if your page has a Favicon which is a suitable size and is delivered with a far-future expiry header. All browsers will request a Favicon on page load and so it is recommended to have one, but also one which is small enough to transfer quickly and which can be cached properly.

    Fixit - Content Distribution Network

  • This test attempts to determine if your page makes use of a CDN, content distribution network. A CDN allows static content to be stored in multiple geographic locations, so that when the content is requested by a user's browser it can be retrieved from a location as close as possible to the user. This geographic proximity increases delivery speed and in turn page load speed.
