how can I stick the div after scrolling down a little

I wanted to stick the 2nd div when we scroll down the page and when the 2nd div meets the top boundary. When it's fixed, it should scroll along with the other pages. How can I achieve this?

#settings{
    width:100%;
    background:#383838;
    height:60px;
}
#menu{
    width:100%;
    position:relative;
    height:100px;
    background:#aaa;
}
#body-content{
    height:900px;
    position:relative;
}

and the HTML

<body>
<div id="top">
    <div id="settings">
    </div>
    <div id="menu">
    </div>
</div>
<div id="body-content">
</div>

</body>

Here in this example http://jsfiddle.net/WBur3/ , the 2nd div should be fixed when we scroll the page. When we scroll up, should turn into the previous state itself. Please help me.

Solution 1:

You can get this effect with jquery

$(function(){
        // Check the initial Poistion of the Sticky Header
        var stickyHeaderTop = $('#stickyheader').offset().top;

        $(window).scroll(function(){
                if( $(window).scrollTop() > stickyHeaderTop ) {
                        $('#stickyheader').css({position: 'fixed', top: '0px'});
                        $('#stickyalias').css('display', 'block');
                } else {
                        $('#stickyheader').css({position: 'static', top: '0px'});
                        $('#stickyalias').css('display', 'none');
                }
        });
  });

NOTE: Don't forget to include jquery library link in your page (assuming you as beginner)

<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>

I would add a comment here but I don't have enough reputation to do that. I was needing something similar in a project and I thought I'd share my changes to @Sowmya's answer. I cleaned the code up a bit and made the scroll effect a lot smoother. JSfiddle

$(function () {
    // Check the initial Poistion of the Sticky Header
    var stickyHeaderTop = $('#stickyheader').offset().top;

    $(window).scroll(function () {
        if ($(window).scrollTop() > stickyHeaderTop) {
            $('#stickyheader').css({
                position: 'fixed',
                top: '0px'
            });
            $('#othercontent').css('margin-top', $('#stickyheader').outerHeight(true) + parseInt($('#unstickyheader').css('marginBottom')));
        } else {
            $('#stickyheader').css({
                position: 'static',
                top: '0px'
            });
            $('#othercontent').css('margin-top', '0px');
        }
    });
});

body {
    font: 13px sans-serif;
}
#stickyheader {
    width: 100%;
    height: 40px;
    background:black;
    color:white;
    margin-bottom: 10px;
}
#unstickyheader {
    margin-bottom: 15px;
}
