What should I do with IE?

Filter: alpha (opacity = 50) is often used in the pop-up layer mask. Is this the solution? Try it. When you find that all texts inherit the translucent attribute.

I have to say that IE has spent a lot of effort on the filter. We can use filter: progid: DXImageTransform. Microsoft. Gradient, right. This is a Gradient filter, but there are two options for achieving background transparency: startColorStr and end. The value of the option is similar to that of RGBA, except that it is changed from 10 to 16, and ALPHA is put in front,

StartColorStr = #00 ffeedd, 00 is transparency, and the rest is the hexadecimal RGB color.

 

Instance:

Filter: progid: DXImageTransform. Microsoft. gradient (startcolorstr = #77000000, endcolorstr = #77000000 );
