Akukho IE 6 okanye 7 ixhasa ipropity property CSS3. Kodwa awunayo inhlanhla. Kunoko, IE isekela ipropati ye-alpha yecrafti ye-Microsoft kuphela. Izihlungi ze-Alpha kwi-IE zamkela iimpawu ezivela kwi-0 (ngokucacileyo ngokucacileyo) ukuya kwi-100 (i-opaque ngokupheleleyo).

ucoca: i-alpha (opacity = 50);

Kufuneka usebenzise i--moz- and -webkit-prefixes ukuze iinguqu zedala ze-Mozilla kunye ne-Webkit iziphequluli zixhase kwakhona:

-blog-opacity: 0.5;
-moz-opacity: 0.5;
opacity: 0.5;

Njalo ubeke i-prefixes kuqala kwi-browser, kwaye i-CSS3 ifanelekile.
