In the world of web development, having a visually appealing and user-friendly interface is essential. The progress bar is a vital aspect of reaching this goal. Progress bars not only give users a sense of readiness and feedback, but they also enhance the overall user experience. Although there are various ways to implement progress bars, CSS offers a flexible and adaptable approach. In this post, we’ll look into CSS progress bars, including its capabilities, stylistic options, and recommended implementation methods.

**Structure of a Circular CSS Progress Bar**
At its core, a progress bar is a graphic representation of the completion status of a task or process. CSS allows developers to create progress bars using simple markup and stylistic techniques without relying on complicated JavaScript tools or frameworks. By employing CSS variables such as width, background-color, and border-radius, developers can adjust the appearance of progress bars to correspond with their design preferences and branding requirements.

**How a circular Progress Bar Works**
A circular progress bar is a visual indicator used in user interfaces to display the status of an operation or process. Circular progress bars fill clockwise around a circle rather than horizontally from left to right. [Read more example of CSS progress bar](https://skillivo.in/understanding-css-progress-bars/)

Let’s break it down step by step:

```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Rotating Circle Border</title>
<style>
  body
  {
    margin: 0 auto;
    width: 500px;
  }
  .circle {
    margin-top:200px;
    width: 400x;
    height: 400px;
    border: 7px solid transparent;
    border-radius: 50%;
    border-top-color: #4caf50;
    animation: rotate 2s linear infinite;
  }

  @keyframes rotate {
    from {
      transform: rotate(0deg);
    }
    to {
      transform: rotate(360deg);
    }
  }
</style>
</head>
<body>
<div class="circle"></div>
</body>
</html>

```
border defines the border of the circle. It is initially set to a fixed transparency of 5 pixels. This means that the border is initially invisible (transparent) but has a width of 5 pixels.

the border radius is set to 50%, which rounds the border to form a circle.

the top color of the border is set from the top edge of the circle color. In this case it is set to #4caf50 which is shaded green.

[The animation property](https://skillivo.in/introduction-to-css-animation-1/) is used to rotate the animation.

@keyframes rotate defines the rotate animation:

1. from specifies the starting state of the animation, where the circle is rotated 0deg (i.e., no rotation).
2. to specifies the ending state of the animation, where the circle is rotated 360deg (i.e., one full rotation).

**Explanation:**

1. When you load this HTML file in a web browser, it displays a webpage with a single circular element (div) that has a rotating border.
2. The border of the circle rotates continually around its center due to the rotate animation defined in the CSS.
3. The animation duration is set to 2 seconds, allowing the circle to complete a full rotation in that time.
4. The animation timing function is set to linear, ensuring constant rotation speed during the animation.
5. The infinite keyword ensures that the animation repeats indefinitely.

**Conclusion**
[CSS progress bars](https://skillivo.in/understanding-css-progress-bars/) are useful tools that help developers design visually appealing and functioning user experiences. Developers can customise the appearance and behaviour of progress bars to their design preferences, improving the overall user experience. By following best practices for implementation, developers may guarantee that progress bars are accessible, performant, and smoothly incorporated into their web apps. With this book, you’ll be well-prepared to grasp CSS progress bars and take your web development projects to new heights.
