And it just became one of the few demos I've made to pass 500 ❤️ on CodePen!
And since FirefoxNightly now supports animating custom properties, it's fully functional there too! Soon, very soon, the animation with work in stable too!

One of my most popular CodePen demos of the past month: cycling gradient text glow codepen.io/thebabydino/...
✨ very little #CSS + a simple #SVG filter
✨ no images whatsoever save for a CSS gradient
✨ no text duplication
✨ cycling gradient effect obtained just by animating a CSS variable

The current @FirefoxNightly has a bit of a transparency issue with #darkreader plugin.
I'm looking forward to the next build that fixes it :)

MCF12: Scarce Time, Even at Night(ly)
There's not been much progress since my last post. Other things cluttered my agenda, and ... I also need my sleep lately, so I could not make up for day-time by using night-time.

@pepikhipik.bsky.social @FirefoxNightly no já jsem se taky zděsil když to na mě dneska vyskočilo. Po odinstalování temného čtenáře už zas weby vypadají normálně.
V normálním firefoxu se ten problém neprojevuje ale já mám rád adrenalin, tak je firefox nightly můj primární browser :troll_face:

New Tab context menu in @firefoxnightly. I find it way cleaner, and less overwhelming.
Give it a go! Enable the “Streamlined tab menu” in `about:preferences#experimental`

As this feature stands today, there is no way to add alt text to the image and it is not included in the PDF/UA tag structure of the document.
I filed a bug:
