I really want to make transparency on my website
because it is lightweight and the effect is charming.
it is done by CSS attribute opacity.
I like to keep my web compatible for FF and IE.
I will go straight to the code.
opacity: .5; //for FF
filter: alpha(opacity = 50); //for IE
1 means visible, 0 means invisible. same for 100~0 in IE.
opacity from 1 to 0 is W3C standard.
This is why I don’t like IE, no standard at all and many more to come.
You’ll see what I mean.
REMARK: This effect needs height and width to work together.
