Summary
For a more intuitive comparison, I have not hidden the raw checkbox.
The above is the content of CSS3 simulating the IOS sliding switch effect. For more related content, please pay attention to the PHP Chinese website (www.php.cn)!

In this post, Blackle Mori shows you a few of the hacks found while trying to push the limits of Cohost’s HTML support. Use these if you dare, lest you too get labelled a CSS criminal.

Custom cursors with CSS are great, but we can take things to the next level with JavaScript. Using JavaScript, we can transition between cursor states, place dynamic text within the cursor, apply complex animations, and apply filters.

Interactive CSS animations with elements ricocheting off each other seem more plausible in 2025. While it’s unnecessary to implement Pong in CSS, the increasing flexibility and power of CSS reinforce Lee's suspicion that one day it will be a

Tips and tricks on utilizing the CSS backdrop-filter property to style user interfaces. You’ll learn how to layer backdrop filters among multiple elements, and integrate them with other CSS graphical effects to create elaborate designs.

Well, it turns out that SVG's built-in animation features were never deprecated as planned. Sure, CSS and JavaScript are more than capable of carrying the load, but it's good to know that SMIL is not dead in the water as previously

Yay, let's jump for text-wrap: pretty landing in Safari Technology Preview! But beware that it's different from how it works in Chromium browsers.

This CSS-Tricks update highlights significant progress in the Almanac, recent podcast appearances, a new CSS counters guide, and the addition of several new authors contributing valuable content.

Most of the time, people showcase Tailwind's @apply feature with one of Tailwind's single-property utilities (which changes a single CSS declaration). When showcased this way, @apply doesn't sound promising at all. So obvio

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
