Exploring animated tabs with a hover nudge. The indicator leans toward whatever tab you're hovering. Two flavors: → constant nudge (every tab leans the same amount). → scaled nudge (the farther the tab, the bigger the lean). Built with Base UI + CSS transitions.

![CSS Trick 🤙 You can create these tab bar controls by using :has() to count the number of tabs ⭐️ .tabs:has(input:nth-of-type(3)){--count: 3;} .tabs:has(:checked:nth-of-type(3)){--active: 200%;} .tabs::after{ translate:var(--active) 0;} Let's break it down in this ! 📼 Couple of CSS :has() tricks here combined with custom properties 😎 First things first, lay out the tabs using display: grid. This gives you a way to create equal-width tabs 🙏 .tabs { display: grid; grid-auto-flow: column; } Then you use :has() to count the number of tabs and store that in a custom property 🤓 .tabs:has(input:nth-of-type(3)) { --count: 3; } .tabs:has(input:nth-of-type(4)) { --count: 4; } Using the cascade, the last valid :has() gives you the number of tabs 🫶 Using the tab count, you can size the tab indicator. For the tab indicator, use the tabs pseudoelement: .tabs::after { content: ""; position: absolute; height: 100%; width: calc(100% / var(--count)); } See how you can use --count to determine its size 📏 Next, use :has() to determine which tab is active or :checked with input [type=radio] .tabs:has(:checked:nth-of-type(2)) { --active: 1; } .tabs:has(:checked:nth-of-type(3)) { --active: 2; } You can use a zero-indexed translation here. If the second input is :checked, set --active: 1, then translate the pseudoelement on the tabs to that position 👉 .tabs::after { translate: calc(var(--active, 0) * 100%) 0; } Or you could set active to the translation: .tabs:has(:checked:nth-of-type(2)) { --active: 100%; } Setting the custom property allows you to use the index elsewhere if you need it 🤙 The final piece is using mix-blend-mode 👀 The tabs have a black background-color, the pseudoelement is white, and the label text is white. When you use mix-blend-mode: difference on the pseudoelement it will give this effect that the text transitions from white to black sliding across 😎 .tabs::after { color: hsl(0 0% 100%); mix-blend-mode: difference; } You can totally mix up the colors here though and go with a different effect. The mechanics of how you can use CSS :has() is the main point here 🙏 As always, any questions, suggestions, etc. let me know CodePen.IO link below! 👇 (There's even a Tailwind CSS play for this one too 👀)](https://image.24vids.com/tw-1750370338041647245/ext_tw_video_thumb/1750367384505081856/pu/img/ZVW6XE5SU4mBEB5M.jpg)
![CSS Tip! 💪 You can create these tab controls with CSS :has() + radio buttons ✨ .tabs:has(input:nth-of-type(3)) { --count: 3; } .tabs:has(:checked:nth-of-type(3)) { --active: 2; } .tabs::after { translate: calc(var(--active, 0) * 100%) 0; width: calc(100% / var(--count)); } Two CSS :has() tricks here combined with a rendering trick 🤙 The tab control is a container using display: grid. You can use :has() to count the number of tabs in the container: .tabs:has(input:nth-of-type(3)) { --count: 3; } .tabs:has(input:nth-of-type(4)) { --count: 4; } Using the cascade, the last valid :has() gives you the number of tabs 🫶 Once you know the number of tabs, you know how to size the indicator: .tabs::after { content: ""; position: absolute; height: 100%; width: calc(100% / var(--count)); } It's a pseudoelement that uses --count to determine its size 📏 The next :has() trick is determining which tab is active or :checked as it's an input [type=radio] .tabs:has(:checked:nth-of-type(2)) { --active: 1; } .tabs:has(:checked:nth-of-type(3)) { --active: 2; } You can use a zero-indexed translation here. If the second input is :checked, set --active: 1, then translate the pseudoelement on the tabs to that position 👉 .tabs::after { translate: calc(var(--active, 0) * 100%) 0; } The last rendering trick is using mix-blend-mode 👀 The tabs have a black background-color, the pseudoelement is white, and the label text is white. When you use mix-blend-mode: difference on the pseudoelement it will give this effect that the text transitions from white to black sliding across 😎 .tabs::after { color: hsl(0 0% 100%); mix-blend-mode: difference; } You can totally mix up the colors here though and go with a different effect.

![New Shop UI with the Emotes tab so far! We're trying to improve functionality and usability with reworking this UI. (everything is subject to change) Big thanks to Cody helping design the UI/UX! If there is anything that you'd think would be helpful with the rework of this do let us know :]](https://image.24vids.com/tw-2045681892444311648/amplify_video_thumb/2045679143564529664/img/ZmHhC5SuzOypuAOl.jpg)
