It is considered a major usability and acceptability bug in IE6 - for a long time it was recommended not to use px
size, as most users will not be able to change it.
Luckily, Microsoft fixed that issue in newer versions of IE.
The mentioned page does not have %
or em
(or ex
, or whatnot), but IE6 supports resizing of some text. For example, the page is using:
<font size="5">President Clinton: "Y2K may doom us all"</font>
Which today is deprecated.
Another common text size supported by IE6 using CSS is
font-size:medium; /*or small, xx-large, etc */
Lastly, IE6 will also resize text with no defined text size at all. The default text is resizeable.
Here's a sample page for your resizing pleasure: http://jsbin.com/ozila/2
