The installation process is relatively easy, the directions straightforward. Simply edit a js file, include it in your source and create the font. Font creation involves the use of the Macromedia Flash editor where you simply select the font you want your text to render in – then export the swf. Font creation can even be sped via automatic sIFR font creation through JSFL, Flash’s internal scripting engine. Overall, getting sIFR onto your site is easy – making it look good is slightly harder.
Overall I really like sIFR – its great for someone who wants total control of design. Perhaps less important to others but designers are a particular bunch. While easy to install – its not easy to tune. Probably the biggest drawback is extra time it adds to your page load. This of course depends on your usage and number of headlines it is replacing.
Not particularly informative but she does hit upon a good practice. It will make it easier on yourself if you first set the letter-spacing and font-size before before tweaking line-height. The line height can drastically alter the size of the box sIFR is trying to replace and skew your letter spacings and font sizes.
