It polyfills scroll(), scrollTo(), scrollBy(), scrollIntoView() and the CSS scroll-behavior. If you need more reassurance, there's a very good smooth scroll polyfill that I use in my projects. scrollTo ( As of this writing, all major browsers – except Safari – support smooth scroll and the scrolling methods described in this article. There's also a new signature for this method, which uses an object instead of two numeric arguments, and with this new signature, we can explicitly set our scroll behavior. You simply call element.scrollTo(x, y) and it'll respect the CSS scroll-behavior of the element. If you have the x and y coordinates for where you want to scroll the user to, you can simply call window.scrollTo(x, y) and it'll respect the CSS scroll-behavior of the page. This method is ideal for scrolling to absolute coordinates. Link Window.scrollTo() and Element.scrollTo() In practice, you can use either, just choose one and be consistent. To avoid duplicate content, I'll just refer to scrollTo(). That's because Window.scroll() and Element.scroll() are effectively the same methods as Window.scrollTo() and Element.scrollTo(). Maybe you've noticed that I haven't mentioned the scroll() method. Link (Note) Window.scroll() and Element.scroll() We'll explore these methods individually. Ğlement.scrollTop = y JavaScript - Window. Some ways of programmatically triggering a scroll event are through: - Window.scrollTo() I say "programmatically triggered" because it's not going to smooth scroll the mouse wheel. scroll-behavior: smooth applies a smooth transition when a scroll event is programmatically triggered.scroll-behavior: instant is the same as auto, which is why it was deprecated.scroll-behavior: auto is the default instant scrolling behavior that we're already used to.The CSS scroll-behavior property accepts one of three values – or two, actually, since one of those was deprecated. Let me introduce you to our tools for a native smooth scroll. querySelector ( href ).Menu Table of Contents CSS scroll-behavior (Note) Window.scroll() and Element.scroll() Window.scrollTo() and Element.scrollTo() Element.scrollLeft and Element.scrollTop (Note) Negative Element.scrollLeft Window.scrollBy() and Element.scrollBy() (Note) Window.scrollByLines() and Window.scrollByPages() Element.scrollIntoView() Browser Support CTA Referencesĭo you want a smooth scroll? Forget JQuery, we're past that. addEventListener ( " click ", clickHandler ) Ĭonst href = this. Again here, all we have to do is set the value of the behavior property to smooth.Ĭonst links = document. This property is the JavaScript representation of the scroll-behavior CSS property and can receive the auto (default), smooth and instant (see upcoming section 7) values. Inside this method, we’ll determine the scrolling behavior via the behavior configuration property. The logic for this approach is similar to the previous jQuery implementation. Using the scroll() Methodįirst, we’ll use the scroll() method. Happily enough, it’s much simpler than you might expect. 5. Smooth Scrolling With Vanilla JavaScriptĪt this point, we’ll throw away jQuery and concentrate on two pure JavaScript solutions. Go with it only if your project already uses or needs jQuery. On the contrary, it's a reliable solution that will work well on different screens/devices, and you can customize the scrolling speed. The major downside of this method is that you have to load an extra JavaScript library. In our case, the animation will last 800ms. Note that the animate() method allows us to adjust the animation speed. Smoothly navigate to the associated section by animating the scrollTop property.Cancel its default behavior to jump to the corresponding section.That said, to create smooth scrolling with jQuery, we’ll take advantage of its animate() method.Įach time we click on a navigation link, we’ll do the following things: We'll continue with the traditional jQuery approach. That said, even Safari, which lacked support in its previous versions, has started supporting it. It's a great and promising CSS feature, and its browser support gradually grows. ![]() Note: if you set scroll-behavior: smooth to the body element, smooth scrolling won't work.Īs an additional note, keep in mind that at the time of this writing, there isn’t any speed option defined in the specification for manipulating the animation speed. As soon as we give scroll-behavior: smooth to the html element, the magic will happen, and we’ll be able to navigate to the target section smoothly. This property accepts two values: auto (default) and smooth. There's a relatively new CSS property called scroll-behavior.
