Putting CSS Anchor Positioning to the test by throwing dropdown menus around 💪 [popover].dropdown { top: anchor(bottom); right: anchor(right); position-try-options: flip-block, flip-inline; } That's all 👆 Keeps the menu tethered to the button

CSS Trick 📜 You can trigger text highlights on scroll with scroll-driven animations 😎 mark { animation: highlight; animation-timeline: view(); } @​keyframes highlight { to { --lit: 1; }} mark span { background-position: calc(var(--lit) * -110%) 0; transition: background 1s; } The trick is using a scroll-driven animation to flip a custom property on a <mark> element 🎚️ You flip the value between 0 and 1, and that transitions the background position of the <mark> element mark { --lit: 0; animation: highlight steps(1) both; animation-timeline: view(); animation-range: entry 100% cover 10%; } The background has to be applied on a child of the mark to see the change in the custom property 👀 mark span { background: linear-gradient( 120deg, yellow 50%, transparent 50%) 110% 0 / 220% 100% no-repeat; background-position: calc(var(--lit) * 110%) 0; transition: background-position 1s; } The trick is to set the background-size so that it's bigger than the element and then split the background-color in the middle using a linear-gradient 🤙 And the property flips fills in the color 🫶 That's it! If there isn't support for scroll-driven animations, use JavaScript's IntersectionObserver API. The code for this is in the demo 😎 Cool example of using CSS as an IntersectionObserver! @CodePen link below 👇
