If you are having font CLS problems on mobile in your NextJS app you might wanna check this out github.com/vercel/next.js/di…
#webperf #nextjs #CLS
Using a Web Font (specially if not from Google Fonts) and having problems with CLS caused by the font swap? Take a look at this article
publishing-project.rivendell…
Notice that the article does not cover size-adjust, so you will need to find that number in a try/fail approach
#webperf
TIL that an HTML comment (<!-- -->) breaks a text tag in 2 and open room for a CLS in the second one when a custom font loads.
Open this pen, throttle your network on devools, open console and rerun the pen. Try the same without HTML comment

More and more 3Ps are taking action on INP, these are the latest examples we are aware of but many others already optimized and others are coming.
It's great to see 3Ps taking an active part in improving Responsiveness on the web.
Thanks to everyone that made this possible.
The team at Google have been working with a number of CMPs (including OneTrust, Complianz and Axeptio), to improve INP by yielding more often—particularly when cookies are accepted. This has resulted in much improved INP for sites using these platforms.

"It takes a village to raise a child" and it's similar with INP issues.
This metric is not a "stick to beat up websites with", as I sometimes hear, but an alert to something that could be improved.
Site owners, third-parties, browser engineers all can help improve the web here.

We’ve released a beta version of web-vitals.js, including a couple of exciting new additions:
- INP breakdown phases
- Long Animation Frame API information for the INP interaction
- Deprecated (but did not remove) onFID
Try it out with:
npm install web-vitals@next – at Paris, France

Esse aqui é apenas um dos vários fervedouros que existem na região do Jalapão. Você sabia que eles podem desaparecer antes mesmo de você conseguir ir até o Tocantins para conhecê-los? Sabia que a ameaça vem de um projeto aprovado ontem na Câmara dos Deputados? Segue o fio...
