Extracting Code from HTML CSS JS with SnappySnippet

In web development, examining website source code can provide valuable insights. However, extracting specific sections requires manually copying each element and related CSS. This laborious task can be simplified with the right tools.

SnappySnippet to the Rescue

SnappySnippet is a handy extension that allows you to selectively copy HTML CSS JS from a specified element in the DOM. It cleans up the extracted code, removes unnecessary attributes, and optimizes CSS for readability.

Implementation Challenges

Developing SnappySnippet presented some unique challenges, which were overcome using the following strategies:

• Using getMatchedCSSRules(): Initially, this method was considered but later abandoned due to issues with matching CSS selectors in the context of HTML snippets.
• Leveraging getComputedStyle(): Instead of inlining all styles, SnappySnippet uses getComputedStyle() to separate CSS from HTML. However, this method returns all possible CSS properties, including defaults.

Addressing Specific Problems

• Removing Default Properties: Comparing element styles within a website and an empty iframe helped identify and remove default browser styles.
• Keeping Only Shorthand Properties: Redundant long-form properties were filtered out by recognizing their shorthand equivalents.
• Removing Prefixed Properties: Browser-specific prefixed properties were removed to avoid potential compatibility issues.
• Combining Similar CSS Rules: Duplicate CSS rules were combined to reduce code redundancy.
• Cleaning Up HTML: jQuery-clean was utilized to reformat and remove unnecessary attributes from HTML code.
• Optional Filters: To prevent potential CSS breakage, all filters are configurable and can be disabled if desired.

With these challenges addressed, SnappySnippet emerged as a valuable tool for web developers, making it easier to extract and experiment with code from a specific element in the DOM.
