I enjoyed Micah R Ledbetter’s SVG triangle of compromise and generally think it’s a fair analysis of how any-which-way you use SVG on a page, you’re giving up some kind of nice ability it could have. For instance, if you use SVG through an <img> tag, it’s cached nicely, but you give up on CSS […]
I like how working on web performance is so well aligned with other worthy goals. A fast site is site more accessible to other people. A fast site tends to convert better. Using web standards and more native web technologies tends to lead to a faster site. SpeedCurve has published a pretty beefy and useful […]
You should know that in-app browser can and do literally inject JavaScript into the websites you visit with them with tracking scripts from the app you’re inside of. And that’s just one thing that sucks about them.

Not everybody has smokin’ fast internet. Wait let me try that again. Most people don’t have smokin’ fast internet, especially not all the time. It’s part of the job to make sure our sites aren’t so slow we’re essentially depriving users access. To experience your site with slow internet, under the Network tab of DevTools […]
This new API enables client-side prerendering, improving performance for users who are likely to visit a new page.
As of March 12th 2023, Interaction to Next Paint (INP) replaces First Input Delay (FID) as a Core Web Vital metric. FID and INP are measuring the same situation in the browser: how clunky does it feel when a user interacts with an element on the page? The good news for the web—and its users—is […]
You want a quick web performance win at work that’s sure to get you a promotion? Want it to only take five minutes? Then I got you. Capo.js is a tool to get your <head> in order. It’s based on some research by Harry Roberts that shows how something seemingly insignificant as the elements in […]
