title: Hide text in H1 tag but not the image
body: <p>I need to hide the text inside a H1 tag. But not the image.
  Problem is that i only can change the css and not the html </p>
  
  <pre><code>&lt;h1&gt;
  &lt;img src="img/headerimg.png" width="900" height="125"/&gt;
  Header 1 text
  &lt;/h1&gt;
  </code></pre>
  
  <p>Is there a way to only hide the "Header 1 text" with only css?
  I'm doing this for big client and they gave me only acces to the css file.</p>
