PNG-8 format image opacity problem in IE8 & IE7
/*by garcon1986*/
I use jquery ui library for displaying several tabs with correspondant contents in my project.
It works perfectly in Firefox and Chrome. When I click a tab different from current tab, it will show the content with new tab clicked.
Here is the correct display for my tabs:
Its css is like this:
Just like what you've seen, the border becomes black, which cause my page disgracefully.
The reason is IE doesn't interprete the opacity of png-8 format image correctly.
For this reason you can use the recommandation solutions of Jack Moore.
Or just change your image format from png-8 to png-24 like me, because IE works with png-24.
Hope this helps!
Enjoy coding!
