[Solved] Opacity

  • I am reading about opacity and they give this example:

    background: rgb(255, 255, 255); background: rgba(255, 255, 255, 0.6);

    What is the point in having the background color repeated twice, with one with opacity? If I take out background: rgb(255, 255, 255); nothing changes.

    Thanks in advance for your help.

  • @jansentina You are right. There is no point in repeating it. You can use the rgba(255, 255, 255, 0.6); alone or you can use the following:

    rgb(255, 255, 255); opacity: 0.6;

    Here's a quick pen: http://codepen.io/srig99/pen/qdIgo.

    Note that opacitychanges the text's opacity that is inside in the div too!

  • It's used as a fallback for browsers that don't support rgba.

    Normally it would look something like this:

      background: white; /* < IE9 */
      background: rgba(255,255,255,0.6);
