Opacity not working with IE 7 and below

Is it worth fixing for IE 7 and below or is most of the market up to date?
If so how would i fix it to work with IE 7 and belowww
Thanks

opacity with CSS or do you mean something else?

If you mean CSS you'll need to use:

Code:

---

filter:alpha(opacity=50);

---

Obviously you'll need to change the value to whatever you want.

Yeh i have it working with firefox and all the up to date browsers just IE 7 doesnt like ittt
