title: Text overlay opacity
body: <p>I'm trying to make an overlay on an image in css but I have some problems I don't know how to solve.
  Check this image out, this is a mockup in PhotoShop:</p>
  
  <p><a href="https://i.stack.imgur.com/K5UaP.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/K5UaP.jpg" alt="enter image description here"></a></p>
  
  <p>but I got this:</p>
  
  <p><a href="https://i.stack.imgur.com/ERIzX.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ERIzX.jpg" alt="enter image description here"></a></p>
  
  <p>As you can see the blockquote and text also have a opacity, this is the only thing I actually need to solve(the blur is not required, would appreciate a good example though)</p>
  
  <p>I also created a codepen, other image, same code</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>img.header {
    width: 100%;
  }
  
  div.wrapper {
    position: relative;
    /* important(so we can absolutely position the description div */
  }
  
  div.description {
    height: 100%;
    position: absolute;
    /* absolute position (so we can position it where we want)*/
    bottom: 0px;
    /* position will be on bottom */
    left: 50%;
    width: 50%;
    /* styling bellow */
    background-color: #cddc39;
    color: white;
    opacity: 0.4;
    /* transparency */
    filter: alpha(opacity=60);
    /* IE transparency */
  }
  
  p.description_content {
    padding: 10px;
    margin: 0px;
    font-size: 30px;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="praktijk" class="col s12"&gt;
    &lt;div class="row pad-top"&gt;
      &lt;div&gt;
        &lt;div class='wrapper'&gt;
          &lt;!-- image --&gt;
          &lt;img class="header" src='https://www.w3schools.com/w3images/fjords.jpg' /&gt;
      ' /&gt;
          &lt;!-- description div --&gt;
          &lt;div class='description'&gt;
            &lt;!-- description content --&gt;
            &lt;p class='description_content'&gt;
              &lt;blockquote&gt;
                This is an example quotation that uses the blockquote tag.
              &lt;/blockquote&gt;
            &lt;/p&gt;
            &lt;!-- end description content --&gt;
          &lt;/div&gt;
          &lt;!-- end description div --&gt;
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
