title: How in Tailwind CSS to use classes with arbitrary values
body: <p>I'm a newbie with Tailwind CSS. By the link <a href="https://tailwindcss.com/docs/just-in-time-mode#arbitrary-value-support" rel="nofollow noreferrer">https://tailwindcss.com/docs/just-in-time-mode#arbitrary-value-support</a> I see that we can use classes with arbitrary values like</p>
  <pre><code>class=&quot;bg-[#1da1f1]&quot;
  </code></pre>
  <p>But browser doesn't see classes containing the characters <code>[</code>, <code>]</code>, <code>#</code> and so on.</p>
  <p>So how to use them or how are they used in Tailwind? I don't get it</p>
