+# CSS Spec references
+
+This directory contains reference materials used to implement a browser-grade CSS cascading module.  
+The goal is to achieve fully spec-accurate `initial` and `inherited` behavior for every CSS property, matching real-world engines like Chromium Blink.
+
+## [`css_properties.json5`](./css_properties.json5)
+
+`css_properties.json5` is a **direct extract of Chromium Blink’s CSS property database**, located at:
+
+[`third_party/blink/renderer/core/css/css_properties.json5`](https://chromium.googlesource.com/chromium/src/+/main/third_party/blink/renderer/core/css/css_properties.json5)
+
+This file is Blink’s _single source of truth_ for all CSS property metadata, including:
+
+- **Property names** (canonical)
+- **Inheritance behavior** (`inherited: true/false`)
+- **Initial values** (`default_value: ...`)
+- **Type information** (`type_name`, value converter)
+- **Longhand/shorthand relationships**
+- **Animation/interpolation flags**
+- **Parsing behavior flags**
+- **Extra property-specific metadata**
+
+Blink uses this file to generate:
+
+- `ComputedStyleBase` fields
+- `ComputedStyleInitialValues`
+- CSS parser logic
+- Style builder code
+
+This means the file embeds the **actual behavior used by Chrome** when resolving CSS cascade and computed style.
