图像内部透明背景色，不受影响

Question

What i want to do is to make a background-color (with opacity) inside a image, there's a way that i can achieve this without being affected by the background-color? The problem here is the background-color with opacity, it makes everything transparent, including the text and the image.
Here's my code:

CSS

 div.Image { background: url("http://fc07.deviantart.net/fs43/i/2009/141/e/e/Vista_orb_by_fediaFedia.png")center center no-repeat; background-size: 40px 40px; position: relative; background-position: 50% 0px; } div.trans-bg { background-color: #646464; opacity: 0.5; border-radius: 3px; border: 2px ridge #7AC3D1; position: absolute; } div.trans-bg p { text-shadow: 1px 2px 2px #000; margin: 5%; padding-top: 45px; width: 100px; color: #fff; text-align: center; } 

 <div class="trans-bg"> <div class="Image"> <p>Windows 7</p> </div> </div>

Answer 1

Try to use rgba instead of the opacity.

background-color: rgba(100, 100, 100, 0.29);

Opacity changes everything contained in the block-level element, whereas setting the opacity with RGBA changes the opacity of the element itself.

First. Youll also want to remove the opactity on the parent div. This will affect all child divs. This is why the BG color on the image div is affected.

    div.trans-bg {
  background-color: #646464;
  opacity: 0.5;
  border-radius: 3px;
  border: 2px ridge #7AC3D1;
  position: absolute;
  }

Next, youll want to use background-color to set the color without affecting the image BG css on the image div.

background-color: #000;
