How to build a progress bar with Tailwind CSS

We’re gonna build this progress bar using Tailwind CSS:

Here’s the code I used to create this bar, and I’ll explain it below.

<div
  class="h-24 bg-cyan-50 rounded-xl border-4 border-cyan-800 overflow-hidden"
>
  <div class="bg-cyan-500 h-full" style="width: 87%" id="progress-bar"></div>
</div>

• The outer div has a defined height and will take up the full width of the page by default.
• I gave the outer div rounded corners and a border. Its background color is the light color you see on the rightmost end of the bar (the unfilled part).
• The inside div has a darker background color, in this case bg-cyan-500. The inside div is the filled part of the progress bar.
• The inside div has h-full, which makes its height the same as the outer div.
• I use a style attribute to set the width of the bar to a certain percentage. In practice, you could use JavaScript to change the width of the bar:

document.getElementById("bar").style.width = `${(11 / 12) * 100}%`;
// Multiplies the decimal by 100 to get a percentage.

Changing the progress bar’s progress using JavaScript.
