How to Selectively Extract HTML CSS JS from a Specific Element of DOM
Introduction
Web developers often need to inspect the source code of websites to understand their markup. While tools like Firebug and Chrome Developer Tools make it easy to inspect code, copying specific sections for local testing can be tedious. This article presents SnappySnippet, a tool that simplifies this process.
SnappySnippet
SnappySnippet is a Chrome extension that enables users to:
- Extract HTML CSS JS from the last inspected DOM node
- Send the extracted code directly to CodePen or JSFiddle
- Customize HTML and CSS cleanup options
Implementation Challenges
First Attempt: getMatchedCSSRules()
- Selectors did not match in the context of the extracted HTML snippet
Second Attempt: getComputedStyle()
- Separating CSS from HTML proved challenging
- Removing properties with default values
- Keeping only shorthand properties
- Removing prefixed properties
- Combining identical CSS rules
- Cleaning up and fixing indentation of HTML
- Adding optional filters to avoid breaking CSS
Conclusion
SnappySnippet is a valuable tool that makes it easy to extract HTML CSS JS from specific DOM elements. Its customizable features allow users to tailor the extraction process to their specific needs.
