jQuery applying css opacity

Question

I have tried to get the opacity to work in IE, I am testing in IE8 at the moment, Chrome etc works fine but IE8 is terrible.

My code has been:

$('#mydiv').animate({'opacity': '0.5'});

and

$('#mydiv').css('opacity', 0.5);

The opacity is applied to the images held within this div but none of the text, it's very infuriating :( can anyone help me? Thanks in advance.

Answer 1

jQuery handles setting the opacity in an IE ≥ 6 compatible way for you, both when using the css("opacity", value) and fade*() methods. But be sure to use the jQuery 1.x library which is compatible with IE 6, 7 and 8 as opposed to jQuery 2.x which is not (both are IE ≥ 9 compatible).

Here are the examples of using css("opacity", value) and fadeTo(duration, opacity):

• jQuery 1.x: http://jsbin.com/xabexa/2/edit?html,js,output
• jQuery 2.x: http://jsbin.com/xabexa/3/edit?html,js,output

However, there are issues in IE ≤ 8 related to opacity of semi-transparent PNGs: How to solve/hack fading semi-transparent PNG bug in IE8?

Answer 2

$('#mydiv').fadeTo(0.5);

or

$('#mydiv').fadeTo(500,0.5);

or

$('#mydiv').fadeTo("slow",0.5);

Answer 3

try with this:

-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=75)"; /* IE 8 */
filter: alpha(opacity=75); /* older IEs */

hope this is helpful for you

Answer 4

IE8 does'nt apply opacity to elements withoute a layout. See this answer Opacity CSS not working in IE8

Answer 5

Try this

filter: alpha(opacity=50);

instead of

opacity:0.5;
