I have a issues with css filters for IE8 ... I have one div with gradient background and this div need to have opacity 0 .. when you hover with mouse over div he get opacity 1 ... my code look like this...
#myDiv {
filter: alpha(opacity=0);
opacity: 0;
background:rgba(75,29,79,0.85); /* For modern browsers */
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(GradientType=1, StartColorStr='#D84B1D4F', EndColorStr='#D84B1D4F')"; /* For IE8 */
}
and then I have hover for this div
#myDiv:hover {
filter: alpha(opacity=100);
opacity: 1;
}
but it does not work .. I guess because it uses both filters, Is there an option that they work together?
Make sure that the display property is set for both. For instance: try setting display:block for the aforementioned div.
Also you can reset the transparency with -ms-filter: "";
Try:
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr="#D84B1D4F",endColorstr="#D84B1D4F",GradientType=1);
Bear in mind that the first 2 digits of your rgb value are setting the opacity so there is no need to use opacity as well. You could use visibility:hidden for example.

Is there a way to fade in an image when a user scrolls the image into view using purely if not mostly CSS?
I have a bunch of images displayed and I'd like the images to appear as they scroll down as a nice effect.
If you want the image to fade in only when the user can see it (after scrolling the page), you can't do it with CSS only. To make the fade in/fade out effect on hover use opacity and transition. Example
img{
opacity: 0.6;
transition: all 1s;
}
img:hover{
opacity: 1.0;
}
If you want to use JQuery, it's possible. See this exmaple.
img
{
opacity:0.4;
}
img:hover
{
opacity:1.0;
}
The CSS3 property for transparency is opacity.The opacity property can take a value from 0.0 - 1.0\
A lower value makes the element more transparent.
img:hover {
-webkit-filter: grayscale(100%);
}

Is there a way to REMOVE completely the Transparency on Toastr.js?
I tried to change the various lines on the .less files
.opacity(#opacity) {
#opacityPercent: 100; // instead of #opacity * 100;
opacity: 1; // instead of #opacity;
-ms-filter: ~"progid:DXImageTransform.Microsoft.Alpha(Opacity=#{opacityPercent})";
filter: ~"alpha(opacity=#{opacityPercent})";
}
and every place where it stated opacity(x) where x was not 1 but it still displays opacity.
I also tried to add the following lines on my own CSS
.toast {
opacity: 1;
}
#toast-container > div {
opacity: 1;
}
but i still get the semi opacity on div message display. On mouse over, the div color becomes full (no transparency). I'm trying to always have it full color (no transparency).
Try overriding it using !important:
.toast {
opacity: 1 !important;
}
#toast-container > div {
opacity: 1 !important;
}
You can also try "inspect element" in Chrome to see which css tag is causing the opacity.
If that doesn't work, can you perhaps provide a link to your page?
It Depends on What You Mean by "Remove"
If you don't want the mixin generating any CSS at all, but also don't want to remove all the mixin calls within the code, then just do this (comment out the code):
.opacity(#opacity) {
// #opacityPercent: #opacity * 100;
// opacity: #opacity;
//-ms-filter: ~"progid:DXImageTransform.Microsoft.Alpha(Opacity=#{opacityPercent})";
//filter: ~"alpha(opacity=#{opacityPercent})";
}
The above will "do nothing." If you want some type of CSS generated (for some reason, I cannot think of why), but you do not actually want to have that code apply any opacity setting in the browser, then give it a bogus value that the browsers will ignore, something like this:
.opacity(#opacity) {
#opacityPercent: bogus;
opacity: bogus;
-ms-filter: ~"progid:DXImageTransform.Microsoft.Alpha(Opacity=#{opacityPercent})";
filter: ~"alpha(opacity=#{opacityPercent})";
}
You can check out that the above generates no opacity within a browser by looking at this fiddle and examining it with an inspection tool (like Firebug, etc.).
I really believe you seek the first option however.
The following works with v2.1.3
#toast-container > div {
opacity: 1;
}
With the !important flag, there would be no fadeIn and fadeOut.
I stumbled onto this site: and started thinking. Is this possible using twitter's bootstrap? I don't see an opacity setting in the css file? Is it as easy as adding it.
In general, this is possible. Testflightapp uses the background-color: rgba attribute with an opacity level.
So if you want to set a background color with opacity to on of you element use this CSS:
elementname {
background-color: rgba(128, 128, 128, 0.5); /* Red [0-255], Green [0-255], Blue [0-255], Alpha [0-1] */
}
If you want to set the opacity on the element as a whole use:
elementname {
opacity: 0.5; /* opacity [0-1] */
-moz-opacity: 0.5; /* opacity [0-1] */
-webkit-opacity: 0.5; /* opacity [0-1] */
}
This is only supported by browsers that support CSS3.
A late answer, but I just found this question whilst looking up something very similar.
If you're using bootstrap with less, so that you're building the css yourself as part of an asset pipeline you should set opacity using the utility macro.
selector {
.opacity(50); /* opacity [0->100] */
}
It'll define the correct browser prefixes, including the IE filter syntax for you.
If you are using bootstrap with sass. You can use the opacity mixin.
#include opacity([from 0-100]);
This will take handle all browser compatibilities (if supported) dealing with opacity.
In my CSS I have the following:
.Thing {
filter: alpha(opacity=40);
opacity:0.4;
-moz-opacity:0.4;
}
.Thing button {
filter: alpha(opacity=100);
opacity:1;
-moz-opacity:1.0;
}
However, the button is still .4 opacity. I then try opacity: 2 and such and it looks like I can give it less opacity but not more. Is there a way I can remove it or do I have to write multiple rules to get everything but the button?
I am testing with Firefox and Chrome.
use rgba with a rgb fallback.
background-color: rgb(0,0,0);
background-color: rgba(0,0,0, 0.5); /*ie6 will ignore this*/
rgba will only apply opacity to the target element.
What i've recently been doing is using the rgbapng sass/compass plugin which generates a png image to use as a fallback for browsers without rgba support.
Note: you'll still need to use an ie6 png fix for this to work.
Not a fix for the opacity issue but a possible workaround.
How about removing the button from the normal document flow and then placing back inside the .Thing

Can I control the visibility of some div in my website and make to become see-through using CSS only? In flash it's done through controlling what is called Alfa so I'm wondering if such a thing exist in CSS!

Can I control the opacity of the div's background only? So the text in the div wouldn't be effected?
You can use opacity in CSS
.transparent_class {
opacity: 0.5;
}
I think there are some problems with opacity in Internet Explorer so here is example how to change transparency in IE:
.opaque1 { // for all other browsers
opacity: .5;
}
.opaque2 { // for IE5-7
filter: alpha(opacity=50);
}
.opaque3 { // for IE8
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
}
HTH
http://www.quirksmode.org/css/opacity.html
.opaque1 { // for all other browsers
opacity: .5;
}
.opaque2 { // for IE5-7
filter: alpha(opacity=50);
}
.opaque3 { // for IE8
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
}
Another way to make only the background transparent is by using a transparent png as background-image, and then use this jQuery fix for the special snowflake IE. This works in all browsers as far as I know.
