Sandrina Pereira

Hi there! Shall we start over? ⚡️ You might know me from Twitter (@a_sandrina_p), occasional workshops or public speaking, and my experimental website sandrina-p.net I'm into React, Headless Design Systems, Accessibility and CSS. Oh, and async remote work! ✨

✍️ Just published a new post about my most-anticipated CSS proposals from Interop 2027! If you’re not familiar, the Interop project is a collaboration between browsers to pick shared focus areas. There’s *so much* good stuff this year, it was hard to pick just 10!

🎉 And we're live! 🎉 We just launched CSS Wrapped 2025: our annual recap of all things CSS & web UI that landed in Chrome over the course of the year. 🚀 This is a big one! We highlighted 22 new features to help you build better on the web. Check out: chrome.dev/css-wrapped-2025

I have a lot of thoughts on AI. I've been working on this post for a couple of months now. It's very personal, characteristically lengthy, and sure to be at least somewhat controversial. Take it (or don't) as you will. joshcollinsworth.com/blog/sloptim...

So yes, you can pass WCAG AA and still fail to comply with the EAA’s digital product obligations... The EAA goes beyond the technical compliance: it requires products to work seamlessly with assistive technologies and be usable across the full customer lifecycle. Not just pass UI-level checks.

front-end should wait less for backends to get started make something desirable, reduce state to a packet later

Container queries aren't about size anymore. Now we have style, scroll-state, anchored, and who knows what's coming? 🤩

A helpful graph made by @stevekrouse.com on the inverse relationship between vibes and understanding in AI assisted code. Put a few thoughts down here: maggieappleton.com/2025-08-vibe... Original article: blog.val.town/vibe-code

I figured out when I like vibe coding: - It’s not important business code - or it’s not to be reusable by others - or it’s just throw away code Basically, vibing is for low-risk boring tasks 🤷

#ChangeMyView AI doesn't make a bad engineer better. It will only make them faster at pushing AI code.

If you struggle to handle many forms at scale, perhaps my talk can inspire you! Full-stack forms with JSON Schemas ⚡️ PS. The conf @jsheroes.io was rad 10/10!

I had so much fun today at @jsheroes.io talking about full-stack Forms with JSON Schemas! And got a sketch out of it, how cool!! ✨✨ Thanks a lot #JSHeroes2025, incredible vibes! 🐻

I'll be at @jsheroes.io talking about handling Forms at scale with JSON Schemas. Based on a true story at Remote.com 💥 Get a ticket and come join us!

✨ In March 2023, I published an article about AI. This was right after OpenAI showcased how GPT4 could turn a hand-drawn sketch of a website into real HTML/CSS/JS. The consensus online was that FE jobs would stop existing within 1-2 years. Well, it’s been 2 years! So, I just published a follow-up:

Who’s joining JSHeroes? I’ll be there talking about… forms with JSON Schemas ⚡️

So… what have you learned in 2025 so far? I haven’t catch up with tech social this year. And it feels… strange. #JOMO

6 #CSS Snippets Every Front-End Developer Should Know In 2025 nerdy.dev/6-css-snippe...

It's 2025. We've *all* been using video calls *extensively* for *at least* 5 years. (8 in my case). We *know* how to share our screen. It works. Let's all finally move away from ❌ "can you see my screen?" + Wait for yes to ✅ "you should see my screen now, shout if you don't" + carry on

When a junior asks you for help in their code, don’t give them the answer right away. Ask them “what’s on your mind?” It’s much better to help them evolve their debugging skills and critical thinking skills. 💡

Everyone is setting their goals. Mine is JOMO: Joy of missing out. Let’s see if I can enjoy not doing it.

If I could, I’d write only CSS / animations for a living ✨

Next time you ask AI about accessibility, please don’t. Here’s why: 🤦

As European Accessibility Act & ADA Title II deadlines near, orgs will suddenly panic about #accessibility, leading to crunch time. Devs'll be frustrated; op-eds'll be penned. Remember, these laws have been on the books for a while. #a11y isn't the villain; your org let you down by failing to plan.

I’m on vacation for 2 weeks. When I come back I can skip my 99+ Slack notifications and get back to speed much faster. How so?⚡️ I leave a “PTO handover & catch-up” doc and my colleagues fill in while I’m out. How cool is that? 😎 Here’s our public template: www.notion.so/remotecom/Su...

I created a personal website starter pack! All the lovely people on this list have ✨fantastic✨ personal #websites or #blogs. 👏 I hope you like it. 🤗 (Feel free to suggest your favorite personal websites as well, of course.) go.bsky.app/QaRNu68

Giving time estimations is a tricky part of the dev flow. What’s your tip? I start: I call it “guesstimation” until I start actually coding it. 🙈

I forgot what it was like to have a feed focused on tech things I actually care about again 🙏

What’s your preferred way to learn about accessibility? Books, Articles, Videos, Codepens, Podcasts, Dev Tools… tell me 👀

#Svelte 5 is out! *checking my portfolio* Svelte 3 + Sapper, from 2019. Oh boy... if ain't broke, don't fix it. 🙈 www.sandrina-p.net

Fixing bugs quickly is more important than not having bugs. Very good grounded reminder from @t3.gg on “Founder mode”. Just do it! ⚡️ youtu.be/tDWs3XU3ESo?...

Accessibility is not just Lighthouse

Next time you say "women have always been in programming" and you get a bunch of replies asking you to prove it, you can link them this blog. dev.to/abbeyperini/...

my main “bluesky tip” is simply — like and follow posts and people you enjoy seeing in your feed, and “show less” what you don’t enjoy. “training” Discover algorithm takes annoyingly long for now — but it does get more specific with time, and the team will be making it more responsive. data helps.

If you care about accessibility and want to not forget using alt text in your images, there's a setting for that

I wrote down some thoughts on two things: ✨ LLMs as a tool for thought. They can be wonderful brainstorming buddies. ✨ Our lives are full of a cycle of taking something in, transforming it, and sending something out wattenberger.com/thoughts/llm... would love to hear your thoughts!

✔️ passed

🌠 For years, the #1 most requested feature in CSS was Container Queries. We wanted them so badly! Well, they’ve arrived… and none of us are using them. 😂 I think I know why, and I just published a new blog post that will hopefully change that! Check it out: www.joshwcomeau.com/css/containe...

💡 aria-label is cool but remember the first rule of ARIA: Do not use ARIA. When possible, consider using a native HTML element visually hidden with CSS (also known as ".sr-only"). Know more reasons why, in this article by @cferdinandi.bsky.social
