[edit] Opera opacity
Opera browsers do not (up to version 9) support css based opacity. Giang Hu presented the following work around to implement semi-transparent layers as overlays on the map. Note that this will not allow you to implement variable transparency on layers in the map ...
I'd found a work around with transparent div on Opera browser in the Internet (I cant remember now).
- Create a semi transparent png image (ex: images/white0.5.png).
- Insert into screen.css following stylesheet:
#kaQuery {
background: transparent url(images/white0.5.png) repeat scroll 0 0;
overflow: hidden; /* make correct tiny selected rectangle in IE */
}
