是否有包含所有CSS属性及取值（含CSS4/模块）的官方完整表格？

Hey there! Great question—lots of developers have hunted for a single, all-in-one official table like the CSS 2.1 property index you referenced, but the short answer is: no, there isn’t an official, single-page comprehensive table that includes every CSS property (including the latest modular specs often casually called "CSS4") and all their possible values.

Why There’s No Single Table Anymore #

CSS has evolved from a monolithic specification (like CSS 2.1) to a modular system. Instead of one big "CSS4" standard, W3C now maintains dozens of independent modules (e.g., CSS Grid Layout, CSS Color Module Level 5, CSS Flexbox Layout) that update at their own pace. Each module defines its own properties, values, and rules, so a single unified table isn’t feasible or maintained by the official body.

Practical Alternatives #

• W3C’s All Properties List: The official list catalogs all standard and candidate CSS properties, but it doesn’t include values directly on the page. To get full value details, you’ll need to click each property to navigate to its parent module’s specification, where you’ll find formal syntax, valid values, and edge cases.
• MDN Web Docs CSS Reference: While not an official W3C resource, this is the go-to for most developers. Every property page includes a complete breakdown of valid values, browser compatibility notes, usage examples, and links to the relevant W3C modules. It’s regularly updated to reflect the latest CSS features.
• Third-Party Curated Tables: Several community-maintained tools organize properties and values into table formats for quick reference. Just make sure to pick tools that are actively updated, since CSS modules evolve rapidly.

Quick Note on "CSS4" #

It’s worth clarifying: "CSS4" isn’t an official version number. W3C abandoned sequential major versioning after CSS3, so all new features are released as updated module levels (e.g., CSS Transitions Level 2, CSS Custom Properties for Cascading Variables Module Level 1). When searching for the latest features, focus on specific module names rather than a vague "CSS4" label.
