How to use HTML and CSS to achieve progress bar effect with transparent dividers in gradient background?

Create a cool gradient progress bar: the perfect combination of HTML and CSS

Many developers pursue more attractive UI elements, such as progress bars with gradients and transparent dividers. This article will explain in detail how to use HTML and CSS code to implement the gradient progress bar shown in the picture, and include eye-catching transparent dividers.

The key to this effect is to cleverly use linear gradient background and mask-image attributes. First, we need a container containing the progress bar, and an internal element that displays the gradient effect. two<div> Elements can be implemented: outer container and inner gradient bar.<p> The HTML structure is as follows:</p> <pre class="brush:php;toolbar:false">&lt;div class=&quot;bar&quot;&gt; &lt;div class=&quot;pattern&quot;&gt;&lt;/div&gt; &lt;/div&gt;</pre> <p><code>bar class defines the overall style of the progress bar, such as width and background color. pattern class is responsible for presenting gradient and transparent separation effects.

The CSS style is as follows:

 .bar {
  padding: 0.5em;
  width: 19em;
  background-color: #000; /* Container background color, customizable*/
}

.bar .pattern {
  height: 2em; /* Progress bar height, customizable*/
  background: linear-gradient(to right, #909 0%, #009 100%) #000; /* Gradient background color, customizable*/
  mask-image: repeating-linear-gradient(to right, #000 0, #000 1em, transparent 1em, transparent 1.5em); /* Create transparent dividers with repeated linear gradients*/
}

In this CSS code, linear-gradient creates a linear gradient from light green to dark green. mask-image property uses repeating-linear-gradient to create a repeating linear gradient as a mask, defining transparent and opaque areas, thus generating transparent dividers on the gradient background. #000 0, #000 1em, transparent 1em, transparent 1.5em section defines the repeating mode of the mask, #000 means opaque, and transparent means transparency. By adjusting the value, the width and spacing of the divider can be controlled. Note that mask-image has browser compatibility issues and may require adding additional browser prefixes, such as -webkit-mask-image .

Through the above HTML structure and CSS style, a progress bar with a gradient background and transparent divider can be achieved. You can modify the color, width, height, and divider styles as needed.
