Outro

What did we cover?

Cut the fat! If it looks like too much markup, it probably is.

Mark titles of works correctly. Don’t emphasize what you can cite.

Review and improve third-party code. Some, much, or most third-party code is, unfortunately, of bad quality. Take a closer look and improve it yourself, if need be.

Keep it simple! (Q.e.d.)

Use lists. When you list things, that is.

Skip type. For style sheets and (JavaScript) scripts, you usually don’t need it.

Work your way up. Or down. Review elements, attributes, contents.

Know the past, know the future. That was probably not a great chapter title.

Ignore AMP. You don’t want it.

Avoid prefetching and prerendering everything. Resource hints are scalpels, not sledgehammers.

Thank you, and see you in the next episode of Upgrade Your HTML!
