Is there a way to make horizontal scrolling smooth

问题:

This fiddle is almost what I'm looking for, I got it from MDN. The only thing missing is that I want to make it smoother. Is there a way to do that without using jQuery or any other plugins?

Fiddle

        var button = document.getElementById('slide');
        button.onclick = function () {
            document.getElementById('container').scrollLeft += 100;
        };

        var back = document.getElementById('slideBack');
        back.onclick = function () {
            document.getElementById('container').scrollLeft -= 100;
        };

This could probably be optimised a fair bit, but here is a basic example of how you could do it using setInterval and clearInterval

Update

Here is another example of it wrapped into a function instead, bit easier to tweak the speed etc.

you can do it vertically with jquery although i'm sure it can be adjusted to be done horizontally. The demo is here

There's a javascript smoothscroll on github too added by cfernandi

Also ccheck out iscroll.js

$(function() {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top
        }, 1000);
        return false;
      }
    }
  });
});

You can also use the .scrollTo method. I've modified the jsFidlle with this javascript :

https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollTo

var container = document.getElementById('container');
var input = document.getElementById('content');
var scrollAmount = 0;
var scrollMin = 0
var scrollMax = input.clientWidth

document.getElementById('slide').onclick = function () {
  container.scrollTo({
    top: 0,
    left: Math.max(scrollAmount += 500, scrollMax),
    behavior: 'smooth'
  });
};


document.getElementById('slideBack').onclick = function () {
  container.scrollTo({
    top: 0,
    left: Math.min(scrollAmount -= 500, scrollMin),
    behavior: 'smooth'
  });
};
