title: Image in H2 (unique per h2)
body: <p>I created a custom H2 CSS markup with gives the H2 a full-with blue background and white letters inside.</p>
  
  <p>Now I want to add a custom small icon in some of these h2's.</p>
  
  <p>for example I have an h2 called Features, now I want to add a small gear icon in front of it.</p>
  
  <p>What is the best way to proceed in terms of:
  - SEO: Is it a problem to have an image inside my h2
  - coding: I just added it as a  inside the H2 tags, but now the image is not aligned in the center (vertically).</p>
