◆ ABOUT THIS TOOL

About HTML to CSS Extraction

Quickly scaffold clean stylesheet declarations from HTML layouts and templates.

When building new web components or converting templates, you often start with an HTML structure full of classes and IDs that have no corresponding CSS stylesheet yet. Manually typing out each selector and converting inline style rules takes valuable time.

The Developers Web Tools HTML to CSS Extractor analyzes the DOM of your markup, extracts all distinct class names and unique IDs, pulls out inline style="..." declarations into organized rulesets, and gathers embedded <style> blocks into a centralized, ready-to-use .css file.

⚙ EXTRACTION ENGINE

Supported Selectors & Extractors

How the extractor processes selectors and style blocks from your markup.

🏷

Class Selectors (`.classname`)

Finds all classes across elements and creates clean CSS rule blocks with comments indicating the total number of times each class was utilized in the markup.

ID Selectors (`#id`)

Detects every id="..." attribute and generates dedicated hashtag ID selector rulesets ready for custom styling.

✎

Inline Styles & Embedded <style>

Converts inline style="..." strings into external CSS declarations attached to compound element selectors, and extracts internal <style> blocks.
