"What's the best way to implement javascript scroll to element smoothly?"
Hey folks! 👋
I’ve been trying to get a smooth javascript scroll to element effect working on my site, but it’s either too jumpy or just doesn’t work at all. 😅
I’ve seen some solutions using `window.scrollTo()` with behavior: 'smooth', but it’s kinda inconsistent across browsers. Anyone got a reliable way to do this without jQuery?
Also, is there a way to add a slight delay or easing to make it feel more natural?
Thanks in advance! 🙏

*PS: If you’ve got code snippets, even better!*
Hey! I've been using `scrollIntoView({ behavior: 'smooth' })` for javascript scroll to element, and it works pretty well in most modern browsers.
If you want more control, check out the `scroll-behavior: smooth` CSS property—it’s a nice fallback. For easing, you might need a lib like *smooth-scroll* or *GSAP* for advanced animations.
Here’s a quick snippet:
```javascript
document.getElementById('target').scrollIntoView({
behavior: 'smooth',
block: 'start'
});
```
Hope that helps!
Ugh, I feel you—browser inconsistencies are the worst! 😤
For a custom smooth scroll effect, I’d recommend using `requestAnimationFrame` with a simple easing function. It’s a bit more code, but way smoother than the native options.
This site has a great tutorial on it: *CSS-Tricks Smooth Scrolling*. Also, *GreenSock (GSAP)* is overkill for just scrolling, but if you’re already using it, their scrollTo plugin is *chef’s kiss*.
Honestly, the native `window.scrollTo()` with `behavior: 'smooth'` is fine for most cases, but yeah, it’s not perfect.
If you want delays or custom easing, try this lightweight lib called *zenscroll*. Super easy to set up:
```javascript
import zenscroll from 'zenscroll';
zenscroll.to('#element');
```
Works like a charm and handles edge cases better than vanilla JS.
Why not just polyfill it? Some older browsers don’t support smooth scrolling, so adding a polyfill like *smoothscroll-polyfill* can save you headaches.
Just install it and call `smoothscroll.polyfill()` once. Then your regular `scrollTo` or `scrollIntoView` will work smoothly everywhere.
Bonus: It’s tiny (~2KB), so no bloat!
For a super simple JS scroll to element solution, I just tweak the `scrollTop` property with a loop and `setTimeout`. It’s not fancy, but it gets the job done:
```javascript
function smoothScrollTo(target) {
const element = document.querySelector(target);
let currentPos = window.pageYOffset;
const targetPos = element.offsetTop;
const distance = targetPos - currentPos;
const duration = 500;
let start = null;
function step(timestamp) {
if (!start) start = timestamp;
const progress = timestamp - start;
window.scrollTo(0, easeInOutQuad(progress, currentPos, distance, duration));
if (progress < duration) window.requestAnimationFrame(step);
}
window.requestAnimationFrame(step);
}
// Easing function (google "easing functions" for more options)
function easeInOutQuad(t, b, c, d) {
t /= d / 2;
if (t < 1) return c / 2 * t * t + b;
t--;
return -c / 2 * (t * (t - 2) - 1) + b;
}
```
A bit verbose, but super customizable!
Hey OP! Just wanted to say thanks for all the suggestions—this thread is gold! 🎉
I tried the `scrollIntoView` method, and it’s way better than what I was doing before. Still testing the polyfill for older browsers, but so far so good.
Quick follow-up: Anyone know how to handle offset for fixed headers? My nav bar covers the top of the scrolled-to element. 😅
(Also, big shoutout to whoever mentioned GSAP—definitely checking that out next!)
If you’re open to libraries, *GSAP’s ScrollToPlugin* is my go-to for buttery smooth scrolling. It handles all the edge cases and lets you add delays, easing, and even scroll horizontally if needed.
```javascript
gsap.to(window, {
scrollTo: "#element",
duration: 1,
ease: "power2.inOut"
});
```
Might be overkill for simple projects, but it’s worth it if you want perfection.
