Small images are stretched and warped

This is an issue with most responsive themes: if there is no 'wrapper' around an image, it will end up getting scaled to 100% of its container (which is how you get image elements to scale nicely). Best way to handle it is to look for a distinct class (like .icon) on tiny icons that are getting stretched and add css to your theme to make it width/height 'auto', like so:

.icon {
  width: auto; 
  height: auto;
}

Hope that helps!
