Using Superscript Text on a Web Page
Monday 26 May 2003
I've spent some time over the weekend investigating ways of making it easier to write blog entries. One feature which I'd like is an simple way of generating footnotes. Ideally I'd like to use the <SUP> tag to display the reference in the text but I found that browser rendering is not up to that yet. If you use superscript you typically get any ugly increase in line spacing.
After much messing around with browser-specific CSS, for example setting the superscript font size to 75% on IE and 50% on other browsers, I realized that although I could get something working for specific browsers and a specific font, as soon as I moved to a different font the line spacing problem appeared again on at least one of the browsers.
This page offers some alternatives. I think I'll go with the first, most simple, approach[1].
