title: Can I add class with only CSS?
body: <p>I'm wondering if I can somehow "inherit" a class property to some elements such as body, like:</p>
  
  <pre><code>.playfont{font-family: 'Play', sans-serif;}
  
  body{.playfont}
  </code></pre>
  
  <p>I know I can do this with JavaScript or LESS, or even adding the class in HTML markup, but is there any pure css way for this?
  Thanks.</p>
