       <h3>Example buttons</h3>
       <p>Button styles can be applied to anything with the <code>.btn</code> applied. Typically you’ll want to apply these to only <code>&lt;a&gt;</code>, <code>&lt;button&gt;</code>, and select <code>&lt;input&gt;</code> elements. Here’s how it looks:</p>
       <div class="well" style="padding: 14px 19px;">
-        <button class="btn primary">Primary</button>
-        <button class="btn">Default</button>
-        <button class="btn info">Info</button>
-        <button class="btn success">Success</button>
-        <button class="btn danger">Danger</button>
+        <button class="btn primary">Primary</button>&nbps;<button class="btn">Default</button>&nbps;<button class="btn info">Info</button>&nbps;<button class="btn success">Success</button>&nbps; <button class="btn danger">Danger</button>
       </div>
