Nice explanation of why CSS is different from other types of programming. It's a positive feature of the Web that we don't have the same control as the printed page. (I keep telling myself.)
“We will prioritize pages with great page experience, whether implemented using AMP or any other web technology, as we rank the results,” Google said in a blog post.This is amazing. The AMP experience in Safari on an iPhone is terrible. AMP doesn’t even do well the thing it set out to do. Add in the way Google HOSTS those pages causing domain confusion and you get a total mess that has only been adopted because Google has monopoly power. Making efficient pages is a good goal but AMP in its current form can’t die soon enough.
"Since most of the time WebP is used alongside JPEG fallback, by using WebP you will essentially double your storage costs with little benefit."ah-HA! Unless all of your images < 500px you don't get a big benefit moving to WebP when you can use MozJPEG for encoding.
