it's that time again — the Q2 '25 CSS nested radius post .parent { --nested-radius: calc(var(--radius) - var(--padding)); } .nested { border-radius: var(--nested-radius); } * realistically these will be static values

been a while since this one has done the rounds — feels like it was almost a meme for a minute 😅 this was a 2023 edition
Now do Apple corner radius 👀
there is in fact an API in the works to do exactly that 🙌
customers: we want better ai apple: heres ui with corners that match the iphone
You could even do nested CSS here!
ha - yes, good spot! missed a trick copying my old caption 🤦😅
nice, well done can you check if you get an updated version, where optical corrections are included? so far you build the circle via math, by changing the radius. when you could adjust the handles that create the radius, that would open up a tremedous new organic options.
@Apple needs this
Show it to Samsung programmers 🙏🏻 they have obvious trouble with it
![CSS Tip! ✨ It's 2024 and you have a new way to make animated borders 🚀 .glow::after { offset-path: rect(0 100% 100% 0 round var(--radius)); animation: loop; } @keyframes loop { to { offset-distance: 100%; }} Using the offset-* properties you can animate elements along the perimeter of others 😍 The rect() value gained support in Safari 17.2 🙌 To start, you create an element and put it inside your main element. For example, you put a span inside the button 🤙 Click me! Make the element fill its parent with absolute positioning and inset [data-glow] { position: absolute; inset: 0; } Now the good part, you use a pseudoelement on that element and define an offset-path [data-glow]::after { content: ""; offset-path: rect(0 auto auto 0 round var(--radius)); animation: loop 2.6s infinite linear; } With the rect value, you are saying the path fills the parent container: top: 0 right: auto || 100% bottom: auto || 100% left: 0 Then you can use round to make sure the path uses the same radius as whatever the parent has The @keyframes animation merely animates the offset-distance of that pseudoelement to 100% @keyframes loop { to { offset-distance: 100%; }} You can see this more clearly in the video 🫶 The offset-* properties also include an offset-anchor property. This allows you to dictate which point of the element follows the path. For example: anchor-offset: 100% 50%; This means that the "right, center" of the element will follow the perimeter of the parent element 🤙 Lastly, the visuals 🎨 For color, you can use a gradient such as a linear gradient to fill the pseudo-element. [data-glow]::after { background: radial-gradient( circle at right, hsl(320 90% 100%), transparent 50% ); } Then clip away everything so you only have the border and can still have translucent backgrounds, etc. Use a mask with mask-composite ✨ A little transparent border trick: [data-glow] { border: 2px solid transparent; mask: linear-gradient(transparent, transparent), linear-gradient(white, white); mask-clip: padding-box, border-box; mask-composite: intersect; } Bit of a long one. Hope you find it useful 🙏 CodePen.IO link below 👇](https://image.24vids.com/tw-1752903535488823789/ext_tw_video_thumb/1752900027591151616/pu/img/d0sViTqgbe8N-yux.jpg)
