<h2>Contextual Backgrounds</h2>
<p>Use the contextual background classes to provide "meaning through colors".</p>
<p>Note that you can also add a .text-* class if you want a different text color:</p>
<p class="bg-primary text-white">This text is important.</p>
<p class="bg-success text-white">This text indicates success.</p>
<p class="bg-info text-white">This text represents some information.</p>
<p class="bg-warning text-white">This text represents a warning.</p>
<p class="bg-danger text-white">This text represents danger.</p>
<p class="bg-secondary text-white">Secondary background color.</p>
<p class="bg-dark text-white">Dark grey background color.</p>
<p class="bg-light text-dark">Light grey background color.</p>
