Smooth page scroll with jQuery

Posted on by jordanhaines

A project I did a few months ago required us to use anchor tags as the pages of information where getting a bit to long for our liking. We don’t mind using them at all, but we did not want the page just to jump to the bottom of the page or just jump to the top of the page. We wanted the page to smoothly scroll to the bottom or top as we thought that this would be a bit more visually appealing.

In this post I will walk you through setting up a demo and giving you the code to make this happen. You can download the source code in Zip format here.

Lets Begin!!!

First we need to set up the folder and file structure that we will be using here. First create a folder called jQuery Page Scroll, In side this folder create a file called index.html and then create two folders called scripts and style. Within the scripts folder create a file called function.js and then in the style folder create a file called style1.css. This will give you your file and folder setup that we will be using in the post.

Lets turn our attention to our index.html file and start to fill that out with what we want. For this post all we are going to is put a load of dummy text into a div and style it quite narrow just to make sure we have to scroll. At the top of the dummy text we will add a link to an anchor at the bottom of the page, then at the bottom of the page we will add a link to an anchor at the top of the page.

Below you can see the html that you will need to copy and paste into your html file:

{code type=html}

The CSS is very simple, all we are doing is making the page wrap div very thin just to make sure we get scrolling. The CSS which you need is below:

{code type=css}
#page-wrap { width: 400px; margin: 20px auto;}

The jQuery that will be using is very simple and in total only comes to 12 lines, now I am no expert in jQuery so the hardcore developers out there could properly find a better way of doing this, but this way works for me and is easy to understand. The jQuery code is below as follows:

{code type=javascript}

$(‘html, body’).animate({scrollTop: $(‘.top’).offset().top},’slow’);

$(‘html, body’).animate({scrollTop: ‘0px’},’slow’);


The jQuery is rather simple, if we take the first function, all we are doing is adding a click event to the html link with a class of bottom. Within the click event we add a function where we add the animate effect to the html and body elements of the our web page. With in the animate effect we add a scrollTop attribute and give the class name of the anchor we want to scroll to. We then add the speed of which we want to scroll, we have set it to slow.

This is my way of using jQuery to give a smooth page scroll, it works for me and has not given me any problems so hope you find it helpful.
