Microsoft Internet Explorer (4.0 and above, Windows-only) supports a proprietary extension to CSS called “filters.” One of these filters is the glow filter. It renders a blurred radiance around an object (or text) so that it appears to glow.
filter syntax will never be implemented in Mozilla, for a variety of reasons:
filteris not defined in the CSS specifications
- The syntax is technically reserved for possible future use, as it is not formatted as a vendor-specific extension
- The CSS3 feature
text-shadow, currently being specified, will offer the same functionality as Microsoft’s glow filter in a standard-compliant form.
Those interested in this functionality may want to watch bug 10713.
