css3 opacity google site - css

i try to make a container for my site in google site that will be transparent so that the
background image will be visible.
i guess opacity property of css3 is not supported by google sites,
so is there any other way to do that? thanx
i tried
filter: alpha (opacity=50); -moz-opacity: 0.50; opacity: 0.50; -khtml-opacity: 0.5; but it's not recognized.
WARNING: Your HTML contains some tags that are not permitted. These have been removed from your changes.

If it allows you you can do that by applying a semi-transparent 1px x 1px .png image to the background of your container.
.yourContainer {
background:transparent url(myTransparentImage.png) repeat;
}

How to fade in image when in view with CSS

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%);
}

How do I remove parent opacity in CSS?

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

thickbox messege alert css change

I'm trying to incorporate thickbox on my site. Basically, it's just a fancy javascript alert with a lot more functionality. However, when you the thickbox appears it darkens the rest of the screen. Id rather not have this. I have searched the CSS file extensively and cannot find how to change the opacity/background color. Any help would be appreciated.
link to CSS file:
http://jquery.com/demo/thickbox/thickbox-code/thickbox.css
.TB_overlayBG {
background-color:#000;
filter:alpha(opacity=75);
-moz-opacity: 0.75;
opacity: 0.75;
}
The "darkening of the screen" is caused by a black overlay with 75% opacity.
Change background-color to transparent if you do not want this.
It's this:
.TB_overlayBG {
background-color:#000;
filter:alpha(opacity=75);
-moz-opacity: 0.75;
opacity: 0.75;
}
You can just empty the content or remove it altogether and problem is fixed!
#riku; you can use rgba for transparent color, like this
css:
.TB_overlayBG {
background: rgba(0,0,0,0.7)
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#4C000000,endColorstr=#4C000000); /* IE 6 & 7 */
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#4C000000,endColorstr=#4C000000)"; /* IE8 */
}
Because rgba is not transparent it's content as opacity does

Make an image transparent in IE to show non-transparent background

I'm trying to get this thing to work in IE (any version - works in FF, Opera, Safari, Chrome ...):
I have a DIV with a background-image. The DIV also contains an image that should be transparent onMouseOver. The expected behaviour now is that the DIV-background would shine through the transparent image (which it does in all browsers but IE).
Instead it looks like the image is getting transparent but on a white background, I can't see the DIV's background through the image.
Here's some code:
<div><img /></div>
And some CSS:
.dojoDndItemOver {
cursor : pointer;
filter : alpha(opacity = 50);
opacity : 0.5;
-moz-opacity : 0.5;
-khtml-opacity : 0.5;
}
.dragItem:hover {
filter : alpha(opacity = 30);
opacity : 0.3;
-moz-opacity : 0.3;
-khtml-opacity : 0.3;
background : none;
}
All of this is embedded in a Dojo Drag-n-Drop-system, so dojoDndItemOver will automatically be set to the DIV on MouseOver, dragItem is set to the href around the image (using the same class on the image directly doesn't work at all as IE doesn't support "hover" on other items that href).
Any ideas? Or is it an IE-speciality to just "simulate" transparency on images by somehow just greying them out instead of providing real transparency and showing whatever is beneath?
a.dragItem {/*Background behind the image*/}
a.dragItem img {/*Image is opaque, hiding the background*/}
a.dragItem:hover img {/*Image is transparent, revealing the background*/}
IE uses the CSS filter:alpha(opacity=x) taken from w3Schools CSS Image transparency. You can also apply it to DIV backgrounds.
div.transbox
{
width:400px;
height:180px;
margin:30px 50px;
background-color:#ffffff;
border:1px solid black;
/* for IE */
filter:alpha(opacity=60);
/* CSS3 standard */
opacity:0.6;
}
I think that filters are a bad idea, so also you can use transparent pngs with IE as shown here.

How can i give transparency effect in CSS?

I am using an image in background of my web page. Now when i uses a table in frontend, i want it to have some transparency effect. ?
How can i do that.
.semiTransparent
{
filter: alpha(opacity = 50);
opacity: .5;
}
this code is not working in CSS file
50% opacity IE:
filter: alpha(opacity = 50);
50% opacity other browsers:
opacity: .5;
The problem with transparency settings in CSS, is that content/text is also semi-transparent, which makes for difficult reading.
A good "cheat" is to use a semi-transparent PNG as a background image for the div/cell. See http://blog.twipler.com for an example and an image from http://blog.twipler.com/twipler/siteimages/white-alpha-thick.png
