One Opinion on Deprecation
When text-resizing widgets were first developed, they were a considerate and helpful addition to any website. With the click of the mouse, people who could not read the text on the page could increase the font size, improving their chance to discern each word.
But that was last millennium. Well, it was not quite that long ago, but it was long enough ago that changes in browsers have made them unnecessary. All — or nearly all — modern browsers have a text resize function built in:
- Press Control + Plus (Command + plus sign on a Mac) and the text size increases through a continuous range.
- Press Control (or Command on a Mac) + minus, and the text size will shrink through a continuous range.
These browser-based commands give the user far better control over font size than any widget can offer. For this reason, accessibility experts now recommend that Web developers stop adding text resizing widgets to their pages.
Where Is Text Resizing Being Discussed?
For a more complete discussion of this point, read Text Resize: A discussion (among our own accessibility group) or the recent WebAxe post, "No to Text Resize Widgets."
