I’m using Chris Pederick’s Firefox addon ‘Web Developer 1.1.6’. I get this warning when hitting a certain web page on my site:
Unknown property ‘MozOpacity’. Declaration dropped.
What does this mean and how can I fix this on my site?
It’s customary for browsers to prefix experimental or proprietary features with -moz (for Gecko-based browsers) or -webkit (for webkit) so they can be used but don’t interfere with standard CSS rendering. In the case of -moz-opacity, it seems that they have finally removed the proprietary tag since the standard opacity tag is supported.
I don’t think any equivalent convention is followed by the IE team, but then again IE is so behind the pack it probably never came up 😉
