To ''increase'' the text size, this example would require a rewrite and lots of testing trial and error. Unfortunately changing text sizes can have a lot of nasty knock-on effects on layout, which cascade out of control in ways that are hard to predict. Hacks such as the above are likely to fall apart if the base CSS changes or if other aspects of the design cause the layout to change. This is in part because this is an override on parts of the base CSS, so effectively a patch, and so has intimate dependencies on its precise content. Also there are dependencies between the (X)HTML and the CSS, so changes to the pages’ content or structure can possibly cause problems.▼
