With such a title for my daily playlist, there's probably little that can go wrong on a monday morning 🥰

Very close to wrapping up a BIG new release for the FrontendFYI Playgrounds — Juuuust need to do some responsive fixes 🫠

When did they add the ability to advance time with Stripe Subscriptions in test mode? This is gold! 🔥

Let's see if Codex is capable of doing something a bit more challenging. Touching quite some files, involving quite a few lines of code.

Exploring OpenAI's Codex a bit. First thing it complains about is me leaving in a placeholder readme and fixing that for me. I like it. It's super accurate too.

Now @gsap-greensock.bsky.social is free, that also means their amazing and versatile Split Text plugin is free too 🔥 Just experimented with it to see how well it integrates with @motion.dev – and I gotta say, this works GREAT! Check the link to the playground below.

The Frontend FYI playgrounds got a visual refresh — better spacing, clearer UI, and just a smoother place to build. No feature changes, just thoughtful tweaks that make it feel right.

Received the first Tesla hate today. People are sad... Driving this car doesn’t mean you idolate Elon. But I get it, this is an easy thing to do.. Luckily this guy “only” wrote SS on my dirty car 🤷‍♂️

Just updated the playgrounds' console to also show logs, instead of only errors. What was I thinking when first building this, showing only errors. Of course you need all these 'here' 'here' 'here' logs 😉 What else would you like to see added?

🔥 Wrapping up the latest Motion course module, and I just couldn't wait to share this! We’re diving deep into the animate() function to build advanced, multi-element animations. This example? Just the beginning of what you'll create! Can't wait to see how you'll use this!

I like these big carousels on pages. But what I don't get is why the engineers took the lazy route here and just added a scrollbar there? On windows this will look even uglier 🤯

Tried to add a simple credits system. Realized the whole account page was trash. Here's the diff from my "quick fix." Ever started with a small feature, only to end up rewriting half the app? 😅

Jeroen Reumkens — Frontend.fyi @jeroenreumkens.com · 07/03/2025
The old account page? Definitely an MVP — and it's been bugging me ever since. With more courses and recipes on the way, it’s time for a real dashboard at Frontend FYI. Oh — and those credits? Soon you’ll be able to unlock content without PRO 👀

Now we've finally ended up at the more complex animations chapter, it is time to start diving into animation sequences. I took inspiration for this lesson from from the Dropbox Brand Guidelines you find here; brand.dropbox.com/logo Beautiful animations on that page!

I love to get comments like these🔥 They are what keep me going! I KNOW my content is awesome, yet it's also so hard to make (enough) money out of content creation as a small creator, as I try to explain to Samir in my comment. Would love to hear you thoughts about this too 🥰

Just gave my PRO page a much-needed update! 🚀 I realized it never fully captured my vision — PRO isn’t just a single course, it’s a growing resource packed with value. This update finally shows that. Check it out, and if you’re on the fence, now’s the time to join PRO! 🔥

Moments like these make me really surprised by today's capabilities of AI. Its able to take a very basic instruction and ugly code from a screenshot (!!), and turn it into something that works perfectly🤯 Sure it's not a 1-1 representation, but that also wasn't what I asked for

First steps towards experimenting with a different type of content😏 Making frontend content is such a serious business. This is gonna be fun on a different level Not sure when I'll be able to create a first video. This was just a fun first experiment. Have a great weekend!

Alright, gonna press the button 🤞 Quite the journey.. Still not entirely sure I didn't miss anything, but this needs to be done now. Took me far more time than I hoped. Let me know if you spot anything that looks off please. Playgrounds are still on V3 for now.

Considering my life choices for choosing Tailwind for my Motion course: Dilemma: Should I update my playgrounds to V4, meaning I need to prompt for all these breaking changes in old save states of users – or should exercises stay on V3 (bad idea too) Plus videos show V3 too!😫

Who said css isn’t a real programming language?! 🤓 Google is working on a first test implementation of if-statements in CSS. What do you think about it? Google’s progress: groups.google.com/a/chromium.... CSSWG Discussion: github.com/w3c/csswg-d...

A while back, I added the ‘by Jeroen’ suffix to my YouTube channel. Today, I took it a step further and replaced the logo with a picture of myself. I’ve realized I’m much more drawn to people than brands—and I want my work to reflect that too. What do you think?

Swapped my 'latest videos' section with a neat scrolling carousel showing the vastness of my content 🤯 Perhaps not the easiest to find the latest content, but it does show how much great content is already out there – which is what the intention of the homepage is imo 🔥

Happy New Year, everyone!✨ After a 2.5-week holiday, I’m back and ready to kick off 2025🔥 So many exciting ideas! We took two trips during the break—Antwerp and Paris—and spent Christmas with family. It was such a great time to unwind and recharge. Did you take some time off?

For the past 3 days I've been trying to loosen this knob on my tripod. What am I doing wrong here? 😂 I can't have tightened it THAT well. Also, what's the +/- dial for? Tried rotating it both ways to loosen the knob, no effect. Can't find it in the manual either. (Manfrotto)

The past 2 days I've been in hyper-focus, building this tagging input for a client of mine. This was definitely NOT easy to build🤯 Got quite far already! Using / hotkey for the category, then select an item, which is inserted as a tag. Including selecting, editing, backspacing!

Anyone who knows why Prettier breaks my code formatting when I nest a code block inside html / JSX, in a MDX file? Apparently many of my snippets have formatting broken now 🥲

Backing projects on Kickstarter always surprises me when VAT + shipping ends up costing nearly as much or more than the initial pledge Even though I expect these fees, the final total still often baffles me. I guess if I waited a bit, I could've bought it for cheaper in NL?

These numbers… for some creators it might feel like nothing. But as a normal human we should not forget how MASSIVE 900.000 is 🤯 Especially being almost all long form content!
