title: Apply style to ALL elements
body: <p>One thing I really like doing is defaulting all of my divs to use</p>
  
  <pre><code>box-sizing: border-box;
  </code></pre>
  
  <p>It makes it very easy to manage element dimensions.  But I want to have this be the default stlye on ALL elements whose display is block and explicitly override this when I need to.  Is there any easy way to do this or do I have to manually specify which elements receive this style?  I know 99% of these issues will be solved with</p>
  
  <pre><code>html, body, div{
      box-sizing: border-box;
  }
  </code></pre>
  
  <p>but there are still plenty of elements that will need this and I'd rather not forget and discover that my page looks like crap.</p>
