The persistent hover state on buttons in touch devices can be a nuisance. To address this, various solutions have been proposed, but none seem fully satisfactory. One approach involves adding a "no-hover" class on touch end, but this negatively impacts performance and doesn't account for hybrid devices. Another option is to add a "touch" class to the document, but this too fails on devices with both touch and mouse capabilities.
The Ideal Solution: CSS Media Queries Level 4
With the advent of CSS Media Queries Level 4, a more refined solution has emerged:
@media (hover: hover) { button:hover { background-color: blue; } }
This media query specifically targets browsers with true/non-emulated hover support (e.g., devices with mouse-like input mechanisms). Buttons in such browsers will display the blue hover effect.
Polyfill for Legacy Browsers
For browsers without this feature, there's a JavaScript polyfill that can simulate true hover support:
html.my-true-hover button:hover { background-color: blue; }
The polyfill detects hovering capabilities and toggles the "my-true-hover" class accordingly:
$(document).on('mq4hsChange', function (e) { $(document.documentElement).toggleClass('my-true-hover', e.trueHover); });
This combination of CSS and JavaScript ensures that hover effects work flawlessly on both modern and legacy touch devices.

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

Autoprefixer is a tool that automatically adds vendor prefixes to CSS attributes based on the target browser scope. 1. It solves the problem of manually maintaining prefixes with errors; 2. Work through the PostCSS plug-in form, parse CSS, analyze attributes that need to be prefixed, and generate code according to configuration; 3. The usage steps include installing plug-ins, setting browserslist, and enabling them in the build process; 4. Notes include not manually adding prefixes, keeping configuration updates, prefixes not all attributes, and it is recommended to use them with the preprocessor.

In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
