Episode notes
Why HTML Evolves Slowly
- HTML evolves more slowly than CSS or JavaScript due to its foundational role and backward compatibility demands.
- This slow pace protects the web's vast existing content from breaking with new changes.
HTML's Resiliency to Errors
- HTML is very forgiving and resilient, continuing to render despite errors or unknown elements.
- New tags like <search> will degrade gracefully in older browsers, not breaking the site.
Using ::details-content Pseudo-element
- Use the CSS pseudo-element ::details-content to select everything inside a <details> except the <summary>.
- This makes styling and animating details elements easier and more precise.
