simple single page layout with html and jquery 0

From this post we are going to learn how to create a single page website layout using only html and jquery.

All we need is your favorite code editor and jQuery library file.

We are going to use html div tags to separate the pages as sections.  Here we are using fixed header to show the section links.

just separate your various page contents in various section divs and header content within header div.

In css we just assign, size of the div. I mean size of the page. In header page link, we need to mention the section id to bring it to top when user click on that page.

Then we can write our javascript code like below.

var from = $("#header").height();
$(document).ready(function () {
    $(".link:first").css("top", from + 'px');
});
$(".jumper").on("click", function (e) {
    e.preventDefault();
    $("body, html").animate({
        scrollTop: $($(this).attr('href')).offset().top - from
    });
});

Here we are using jQuery method .animate() to scroll
the page. In this we are using scrollTop attribute to scroll the clicked section to the top of the page.

In the above code we used minus some value in scrollTop attribute of .animate() method. Because in this example we are using fixed header. If we use scrollTop attribute like below,
scrollTop: $($(this).attr('href')).offset().top

top of our section div contents will hide behind header div. So, we get the height of header div using,
var from = $("#header").height();

and reduce it from the top like this,
 scrollTop: $($(this).attr('href')).offset().top - from
By this, our section div content will display below to header div.

have you seen this line in the above code? could you guess why we using this?

$(".link:first").css("top", from + 'px'); 
 Already I told, we are using fixed header for menu. So, the first section div will hide behind that header div. For that, we get the header div's height and assign that height value to first section div.
For example, if
var from = $("#header").height();
return 85 to variable from, when we use this below code in document ready,
$(".link:first").css("top", from + 'px');
our first section div's css looks like,
.link:first {
   top:85px;
}
Here is the DEMO
