(Davidson wasn't alone, he and Mark Wubben worked along with a invaluable stable of beta testers, supporters, and educators like Stephanie Sullivan and Danilo Celic of Community MX, worked to completely rebuilb a DOM replacement method originally conceived by Shaun Inman.)
What sIFR allows one to do is deliver your preferred typefaces to viewers, particularly useful for maintaining consistency across print and www. It's a no-no for entire pages of copy, paragraphs, et al., and instead suggested for headlines, pull quotes, and other small swaths of text. In other words, it is for display type — type which accents the rest of the page. Body copy should remain browser text.
How it works
- A normal (X)HTML page is loaded into the browser.
- Once measured, the script creates Flash movies of the same dimensions and overlays them on top of the original elements, pumping the original browser text in as a Flash variable.
- Actionscript inside of each Flash file then draws that text in your chosen typeface at a 6 point size and scales it up until it fits snugly inside the Flash movie.
