CSS 3 Opacity Image

Wednesday, November 4th, 2009

How to make Opacity Image using CSS 3 ?

Before there was CSS 3, to get a transparent effect on the image in the browser, the web designers using image transparent PNG format.
You can achieve a similar effect by using the opacity property. Now, the opacity property has been around for a while, but our beloved IE has its own properties.

Example css 3 image opacity:

<html>
<head>
  <title> Opacity Image using css3</title>
  <style type="text/css">
  .img_opacity {
  opacity: .6; // all modern browsers (this is CSS3)
 -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
 //IE 8
  filter: alpha(opacity=60); // IE 5-7
  }
  </style>
</head>
<body>
<img src="http://localhost/cs3/images/photo6.jpg"
          width="241" height="228"/>
</body>
</html>

The Result:
image opacity

In modern browsers like Safari, Google Chrome, Firefox, you simply write CSS code like below:

.img_opacity {
         opacity: .6;
         }

CSS 3 Background Color Opacity

How to make Background Color Opacity using CSS 3 ?

Everyone knows what RGB stands for (red, green, blue), but what does the A stand for?
It stands for Alpha, which refers to the transparency.

Other than rounded corners, RGBA is my next most used CSS3 property. Sometimes I just want to add a few light white/black background to navigation links when a user hover overs them. It’s much easier than creating a new image for each color. but using css3 property you can make background with opacity.

Example css3 background :

<html>
<head>
  <title>Background Color Opacity</title>
  <style type="text/css">
    .rgba {
       width:200px;
       text-align:center;
       padding:10px;
       background: rgba(239, 182, 29, .50);
       }
  </style>
<body>
  <div>how to make background color opacity</div>
</body>
</html>

The Result:

Background color with opacity
Background color opacity none
