CSS Opacity and Internet Explorer #121

Closed jacobbuck closed 11 years ago

jacobbuck commented 11 years ago

Setting opacity to 0 does not work in IE 8 and older, however "0" does work. And setting it to null or "" does not work in IE 9 and older.

Also when setting the opacity through the IE Developer Tools console starts using the filter property in IE 9, and doesn't work at all in IE 10.

We probably need to switch this to a check for != 'object': https://github.com/ded/bonzo/blob/8b616a4ab7df00693629670399585f292b2a087a/src/bonzo.js#L785

and this should probably include a check for opasity to include the feature detect instead of just the the ie check: https://github.com/ded/bonzo/blob/8b616a4ab7df00693629670399585f292b2a087a/src/bonzo.js#L790

I'll have a go when I find the time unless @jacobbuck you want to submit a pull request for this? Or perhaps @ded (or someone else watching) has time.

Yep, I just noticed the ie check too, also in the same statement iter.opacity would return false if equal 0. And if the opacity was null or "", it would still apply the filter property with a value of 0.
