💡 Best Practices

Do

  • Type 7 directly in normal prose when you can
  • Use numeric references in generated HTML output
  • Use \0037 in CSS content when needed
  • Keep encoding consistent across templates
  • Prefer semantic markup for lists (<ol>)

Don’t

  • Over-escape digits in static content without need
  • Use CSS escapes inside HTML text nodes
  • Assume entities improve accessibility (rendered output is identical)
  • Mix reference styles randomly (hex vs decimal) in one section
  • Use entities in JSON/JS strings (use the literal character)
