Smooth scrolling when clicking an anchor link on react/next.js

Is it possible using only CSS to make smooth scrolling when clicking an anchor link in react component?

...
render(
    <a href="#smooth-link">Link To There</a>
    ....
    <div id="smooth-link">
        ....
    </div>
)

Answer

There’s this:

/**
 * Smooth scrolling inside an element
 */
#my-element {
    scroll-behavior: smooth;
}

/**
 * Smooth scrolling on the whole document
 */
html {
    scroll-behavior: smooth;
}

But I feel like JS does a better job:

document.querySelectorAll('a[href^="#"]').forEach(anchor => {
    anchor.addEventListener('click', function (e) {
        e.preventDefault();

        document.querySelector(this.getAttribute('href')).scrollIntoView({
            behavior: 'smooth'
        });
    });
});

So you could give that a try: docs
