DOM magnifier with CSS && SVG 🔍 .magnifier { position: fixed; left: 0; top: 0; translate: var(--x) var(--y); backdrop-filter: url(#magnifier); } Could use it in a [popover] 🤙

Here's the @CodePen 🤙 Shame about the Firefox && Safari compatibility 🙃 There is probably a way to get the SVG filter working But still makes for a cool demo magnifier in a Chrome extension 👀
Prompted by the recent CodePen filter challenge ⭐️ Went poking around, here's a good article over on @smashingmag that digs into using displacement filters to achieve different effects 🙏 Covers some of the support gotchas too!
The tweet showcases a CSS & SVG-based DOM magnifier that could be used in a popover. Interesting approach to implement a magnifier UI element.
@jordanmoore 👀
SVG stuff is so cool. I feel like there's a lot of stuff we can do with those filters that I'm just not aware of yet.
Super cool
Awesome!
Wow! Well done!
I wanna have your grid background. Please. Sir.
Hey @jh3yy can I use this in one of my projects?
![neat trick for the sheet effect by transforming the body with CSS when you have :popover-open ✨ :root:has(.drawer:popover-open) body { scale: calc(0.95 + (var(--c) * 0.05)); translate: 0 calc(.875rem * (1 - var(--c)); } [popover] isn't affected as it's in the :top-layer 🚀](https://image.24vids.com/tw-1847369237938995665/ext_tw_video_thumb/1847367287357194240/pu/img/DI1UxJs_Ypjgq5r4.jpg)
![Future UI && CSS Tip! 🔮 You could use View Transitions to animate CSS grid position and create an OSX-style exposé for a portfolio 🔥 It's a grid where things move based on state. Wrapped in a VT 🤙 [data-expose] section{ grid-area:var(--x)/var(--y); } CodePen.IO link below 👇](https://image.24vids.com/tw-1684294735228289026/ext_tw_video_thumb/1684293327405871106/pu/img/_8tGY2yw7r3sRTOo.jpg)
![CSS Tip 🤙 You can create this header effect using position: sticky, clip-path, and custom properties 🔥 (Video 👀) header { position: sticky; top: var(--margin); } main { clip-path: inset(var(--header) 0 0 0);) } No mix-blend-mode or animations required ✨ What's the trick then? 🧐 Duplicate the header element first. Then fix the positioning of one behind the content. header[aria-hidden] { position: fixed; top: 0; margin-top: var(--margin); } Clip the top of the content to reveal the fixed header and put a sticky-positioned header inside it that matches up in position and size ✂️ :root { --header: calc(var(--margin) + var(--font-size)); } main { clip-path: inset(var(--header) 0 0 0); } header { position: sticky; top: var(--margin); } Make your life easier with custom properties 🙌 As the body scrolls, the fixed header gets covered by the clipped content and creates the effect ✨ And because the sticky header is "stuck" it reveals itself as the content goes out of view 😍 This one's pretty cool. You can set the font color to whatever you want. At first glance, it looked like it was a mix-blend-mode thing. It doesn't have to be! Think about it and lean into z-indexing 🫶 Watch the video to get an idea of things with the exploding view 🤯 Any questions, etc. let me know! Will likely do a YouTube video on this one too! 🙏 CodePen.IO link below! 👇](https://image.24vids.com/tw-1742391976517927321/ext_tw_video_thumb/1742387238879514624/pu/img/qhFKDDbPrYvBH8B6.jpg)
![CSS Trick 🧲 You can create magnetic links with the power of custom properties and some JavaScript 💪 a { translate: calc(clamp(-1, var(--x), 1) * var(--pad-x)) ...; transition: translate var(--s, 1s) var(--ease, var(--elastic)); } a:hover { --s: 0s; } The trick here is to pad out the list items wrapping your links and use that as a translation limit 🛑 Start by using some JavaScript to calculate a value between -1 and 1 for both the x/y axis on pointermove for each list item, not the link! 🔗 If your pointer was at the center of the item, you'd get [0,0]. If it was in the top right, you'd get [1,-1] ☝️ It's worth checking out the JavaScript snippet to see how the mapping function works. Essentially, you create a function that when given a value between two bounds, will give you a mapped value back 🤙 const mapX = mapRange( item.offsetWidth * -0.5, item.offsetWidth * 0.5, 1, -1 ) Then, on pointermove, you plug the pointer position in to get the value back out and pass that into your CSS const x = mapX(item.centerX - event.x) document.documentElement.style.setProperty(--x, x) When the pointer leaves the list item, you make sure to reset these values back to 0 ✨ Once CSS has your values, it's the trick of updating the translation of each part You know that in each axis, you only want to translate the link by the padding amount li a { translate: calc(clamp(-1, var(--x), 1) * var(--pad-x)) calc(clamp(-1, var(--y), 1) * var(--pad-y)); transition: translate var(--speed, 1s) var(--ease, var(--elastic)); } This will translate the link within the list item by the desired amount. The cool part here is that you can set an offset for the text inside the link and have that move at a different rate ⭐️ By only updating the --pad-x/y custom properties for the inside the link, you can control how much it moves nav a span { --pad-x: 0.25rem; --pad-y: 0.25rem; } And the last piece, how do you update the behavior for transition speeds? And so it springs back like that? Again, use custom properties ✨ a:hover { --s: 0s; } a { transition: translate var(--s, 1s) var(--ease, var(--elastic)); } By default, a link will use --elastic easing via linear() and have a transition-duration of 1s. When a link is hovered that speed becomes 0s because you want the link to magnetise to your pointer. How about that little gap between when your pointer enters the item but hasn't hovered the link? Set a different transition so it transitions to being hovered 🫶 nav li:hover a { --ease: ease-out; --speed: 0.1s; } That's kinda it! 🙌 Use JavaScript (~40 loc) to get the information and then let CSS do all the lifting for you 💪 Any questions or suggestions, let me know 🙏 If you want a walkthrough video, also let me know please 🙏 CodePen.IO link below 👇](https://image.24vids.com/tw-1745716136824672271/ext_tw_video_thumb/1745612660081881088/pu/img/SsGz-uqmfdr1KZ7H.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. 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-1746099478656901617/ext_tw_video_thumb/1746099293872898048/pu/img/oonp9Ek6MULFcFjk.jpg)
