title: Are multiple CSS classes per tag safe to use?
body: <p>I am starting up a brand new web project and would like to know if I can safely use multiple CSS classes nowadays.</p>
  
  <p><code>&lt;div class="float-left bold bordered"&gt;&lt;/div&gt;</code></p>
  
  <p>Do most common browsers support this, or will a significant percentage of my visitors run into major trouble viewing the page?</p>
  
  <p>I'm not worried about special cases like Netscape 1.0 users, but browsers and versions usually used in companies these days.</p>
