Understanding Image Compression: Tooling and Context

Image compression is an important part of performance optimization. It seems straight-forward but is a little deceptive, however, because it consists not of one but two parts—and it’s usually lack of understanding of one part that causes problems.

Optional @lang

The lang attribute is one of HTML’s global attributes. If one doesn’t simply take it for granted, it begs a number of questions—and these suggest to drop W3C requirements around it, and to demand software to do the job.

HTML and Performance: Leave Out Optional Tags and Quotes

As experts we should know what code is optional and leave it out, and our production systems should do a better job assisting us with that. After all the years of neglecting basic HTML optimization, let’s think about taking the next step and not ship optional HTML markup.

On Performance Visions, or: Performance Optimization Is a Process
