Html Vs Xhtml in HTML
HTML vs XHTML
| Feature | HTML | XHTML |
|---|---|---|
| Definition | HyperText Markup Language – a markup language to create web pages | Extensible HyperText Markup Language – stricter, XML-based version of HTML |
| Syntax Rules | More flexible syntax | Strict syntax (must be well-formed XML) |
| Tag Closing | Optional closing tags for some elements (e.g., <br>, <img>) allowed | All tags must be closed (e.g., <br />, <img />) |
| Case Sensitivity | Tag and attribute names are case-insensitive (usually lowercase) | Tag and attribute names must be lowercase |
| Attribute Quotation | Quotes around attribute values are optional | Quotes required around attribute values |
| Error Handling | Browsers are forgiving and try to fix errors | Browsers treat errors strictly and may fail to render |
| Document Declaration | Uses <!DOCTYPE html> (HTML5) | Requires XML declaration and specific DOCTYPE |
| Compatibility | Works on all browsers easily | Requires XML-compatible browsers and careful coding |
Summary:
HTML is simpler and more forgiving — ideal for most websites
XHTML is stricter and enforces good coding practices, useful if you want XML compatibility
Example:
HTML:
<img src="image.jpg" alt="Sample image">XHTML:
<img src="image.jpg" alt="Sample image" />Want me to show how to write a valid XHTML document or discuss when to use XHTML?
