CSS重置通過(guò)移除所有默認(rèn)瀏覽器樣式提供完全控制，而Normalize則修正差異同時(shí)保留有用默認(rèn)值。1. CSS重置將樣式歸零以消除不一致，適用于高度定制化UI；2. Normalize平滑瀏覽器差異并保留可讀性與可用性，適合注重可用性與可訪問(wèn)性的項(xiàng)目；3. 選擇取決于需求：需全面控制用Reset，需保留默認(rèn)并統(tǒng)一用Normalize；4. 部分開(kāi)發(fā)者結(jié)合使用，先Normalize再局部重置。兩者核心區(qū)別在于Reset從零開(kāi)始，Normalize修復(fù)已有問(wèn)題。

The purpose of a CSS reset and a normalize stylesheet is to help make websites look more consistent across different browsers, but they approach the problem in different ways. A CSS reset strips away all default browser styling, giving you a blank slate to work from. Normalize, on the other hand, aims to make built-in browser styles more consistent without completely removing them.

CSS Reset: Starting From Scratch

A CSS reset removes all default browser styles so that every element looks the same across browsers — or rather, doesn't have any style at all until you add it.

• It targets elements like headings, paragraphs, lists, buttons, and form controls.
• The idea is to eliminate inconsistencies by "resetting" everything to zero or neutral values.
• Popular resets include Eric Meyer’s Reset and the simple * { margin: 0; padding: 0; } style.

Example use case:
If you're building a highly customized UI and want full control over every element's appearance, a reset can be helpful. It avoids surprises from browser defaults.

One thing to note: Resets can sometimes be too aggressive. For example, resetting margins and paddings globally might cause text spacing issues if not carefully managed later.

Normalize.css: Taming Browser Defaults

Normalize.css doesn’t remove styles — it smooths out differences between browsers while preserving useful defaults.

• It fixes bugs and inconsistencies (like HTML5 element display settings).
• It maintains readability and usability for things like form controls and tables.
• It's modular, meaning you can customize which parts you want to include.

Why it's useful:
You get a more consistent baseline without having to re-style everything from scratch. For example, it ensures that <sup></sup> or <sub></sub> tags behave similarly in Chrome and Firefox.

Normalizing also helps with accessibility — it preserves default focus outlines and form behavior, which resets often strip away unintentionally.

Which One Should You Use?

It depends on your project and how much control you need:

• ? Use a CSS reset if:

  • You want total control over every style
  • You’re building a heavily customized design system
  • You don’t mind re-defining basic typographic styles

• ? Use Normalize.css if:

  • You want consistency without throwing out browser defaults
  • You're working on a site where usability and accessibility are important
  • You prefer starting with something usable rather than a blank slate

Some developers even combine both approaches — using Normalize first and then applying light resets selectively.

Basically, the difference comes down to this:
Reset says, “Let’s start over.”
Normalize says, “Let’s fix what’s broken.”

And depending on your needs, one may suit you better than the other.
