I’m sure you have seen this: you click a button and smoothly scroll to that section.

Today we are looking at implementing a smooth scroll into view in Vanilla JavaScript by using the Element.scrollIntoView() function.

HTML Structure

Let’s set up a small demo to demonstrate this. The demo code will have a fixed header with some buttons and four sections to which we can scroll.

    <a href="#" data-target="section-1" class="btn-scroll-into">Section 1</a>
    <a href="#" data-target="section-2" class="btn-scroll-into">Section 2</a>
    <a href="#" data-target="section-3" class="btn-scroll-into">Section 3</a>
    <a href="#" data-target="section-4" class="btn-scroll-into">Section 4</a>
<section id="section-1">Section 1</section>
<section id="section-2">Section 2</section>
<section id="section-3">Section 3</section>
<section id="section-4">Section 4</section>

As you can see, nothing fancy. Note that we added data-target attributes to our header navigation items and a class of btn-scroll-into. Read more about data-attributes.

CSS for our scrollIntoView demo

body {
  padding-top: 50px;
header {
  position: fixed;
  height: 50px;
  background: #345995;
  width: 100%;
  top: 0;
header nav {
  height: 100%;
  display: flex;
  justify-content: space-around;
  align-items: center;
header nav a {
  padding: 5px 10px;
  background: #03cea4;
  border-radius: 10px;
  color: #fff;
  text-decoration: none;
section {
  width: 100vw;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
  color: #fff;
  font-size: 32px;
  background: #ca1551;
section:nth-child(odd) {
  background: #fb4d3d;

Really nothing special here. We offset our body by 50 pixels since we use a fixed header that will always stay on the top of our screen. And add some 100% sections by utilising viewport units and flex box centering.

JavaScript scrollIntoView

document.addEventListener('click', function (event) {
  if (!'.btn-scroll-into')) return;


  const element = document.getElementById(;


Yep, that is all! We added an event listener, which will fire each time we click; we then check if the element we click has the class btn-scroll-into. We then define an element variable by using getElementById and passing the dataset attribute called target.

Then all we do is say element.scrollIntoView(); this will put the element we selected at the top of our page.

You can see the example in action on this Codepen

ScrollIntoView options

This is now a hard switch, but it allows options which are the following:

  • behavior: auto or smooth
  • block: start, center, end or nearest (default: start)
  • inline: start, center, end or nearest (default: nearest)

So let’s make it scroll smoothly:

element.scrollIntoView({ behavior: 'smooth' });
