This morning design CSS for simplescratch.com and try to implement opacity feature on CSS3, but ups it’s not working on IE.. wew.. I hate IE.. haha so I need to fix it. Let’s searchin on Google.. and ahaa i found it. This is how to fix opacity on IE. Let me share to you..
.change_opacity {
opacity: 0.5; /*on mozilla*/
filter: alpha(opacity = 50); /*on ie*/
}
Just change the value for opacity that you want. ^^
