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.

Describe different CSS units and when to use them
Jul 27, 2025 am 04:24 AM
In web development, the choice of CSS units depends on design requirements and responsive performance. 1. Pixels (px) are used to fix sizes such as borders and icons, but are not conducive to responsive design; 2. Percentage (%) is adjusted according to the parent container, suitable for streaming layout but attention to context dependence; 3.em is based on the current font size, rem is based on the root element font, suitable for elastic fonts and unified theme control; 4. Viewport units (vw/vh/vmin/vmax) are adjusted according to the screen size, suitable for full-screen elements and dynamic UI; 5. Auto, inherit, initial and other values are used to automatically calculate, inherit or reset styles, which helps to flexibly layout and style management. The rational use of these units can improve page flexibility and responsiveness.
