How to implement segmenter with 45 degree curve effect through CSS and JavaScript?

CSS and JavaScript create 45-degree angle curve segmenter

In modern web development, exquisite UI design is crucial. This article will demonstrate how to use CSS and JavaScript to create segmenters with 45-degree angle curve effects to improve the user interface aesthetics and interactive experience.

The core technology lies in cleverly using CSS clip-path attributes and path functions. By defining custom paths, dynamically adjusting their borders when the tag is activated, resulting in a smooth curve effect.

The following CSS code snippet shows the key styles:

 .tab.active:before {
  content: '';
  position: absolute;
  top: 0;
  left: -50px;
  height: 100%;
  width: 50px;
  z-index: 2;
  background-color: #fff;
  clip-path: path('m 0,50 c 25,50 25,0 50,0 l 50, 50 z');
}

.tab.active:after {
  content: '';
  position: absolute;
  top: 0;
  right: -50px;
  height: 100%;
  width: 50px;
  z-index: 2;
  background-color: #fff;
  clip-path: path('m 0,0 c 25,0 25,50 50,50 l 0, 50 z');
}

clip-path: path(...) defines the curve paths on the left and right sides through the path function. m means moving to the starting point, c means c as a cubic Bezier curve, and l means a straight line. When the tag is activated ( active class), these two pseudo-elements ( :before and :after ) generate curve borders.

JavaScript code is responsible for managing the activation status of tags:

 function initData() {
  return {
    activeIndex: 1,
    onTabClick(index) {
      this.activeIndex = index
    }
  }
}

This Alpine.js-based code handles the tag click event concisely. The onTabClick function updates activeIndex , thereby controlling the application of CSS styles and realizing the switching of curve effects.

Through CSS' clip-path and JavaScript event processing, we can efficiently create segmenters with 45-degree angle curve effects, adding a touch of modernity to your web applications.
