</html>Good practice:
-
Tables used for tabular data, not for formatting
-
Images all have alt text
-
Headers used properly - smaller headers used to section content demarcated by larger headers
-
One h1 per page
-
h2s used to demarcate large sections of the page
-
h3-6 used for subsections
-
-
No tags that exist for no reason- all tags should have a purpose
