    How to add go to top and go to bottom buttons Using jQuery in Blogger




    The Up and Down buttons can be used to navigate to the top and bottom of the page content, especially when on the main page are many articles or when an article has too many comments. These buttons have a fadeIn and fadeOut effect, this means that they will fade slightly when we are scrolling to the top or bottom of the page and additionally, have the function of going up/down the blog.

    .button_up{
    padding:7px; /* Distance between the border and the icon */
    background-color:white;
    border:1px solid #CCC; /* Border Color */
    position:fixed;
    background: white url(http://4.bp.blogspot.com/-7zE5N9GdDUk/T6rH17KE6II/AAAAAAAACeQ/aEcKRyEhxsE/s16/arrow_up.png) no-repeat top left;

    width:20px; /* Button's width */
    height:20px; /* Button's height */

    right:5px; /* Change right to left if you want the buttons on the left */
    white-space:nowrap;
    cursor: pointer;
    border-radius: 3px 3px 3px 3px;
    opacity:0.7;
    filter:progid:DXImageTransform.Microsoft.Alpha(opacity=70);
    }
    .button_down{

    background-color:white;
    border:1px solid #CCC; /* Border Color */
    position:fixed;
    background: white url(http://3.bp.blogspot.com/-sukwuViZaYY/T6rH15A8niI/AAAAAAAACeM/YErd0S8lPGA/s16/arrow_down.png) no-repeat top left;
    background-position:50% 50%;
    width:20px; /* Button's width */
    height:20px; /* Button's height */
    bottom:242px; /* Distance from the bottom */
    right:5px; /* Change right to left if you want the buttons on the left */
    white-space:nowrap;
    cursor: pointer;
    border-radius: 3px 3px 3px 3px;
    opacity:0.7;
    filter:progid:DXImageTransform.Microsoft.Alpha(opacity=70);
    }
    Note:  - in green are some annotations that explains what styles you can modify on their left side.
               - You can change the arrows by changing the URLs in blue.
               - To change the buttons background color of buttons, change the white text with your color

    Step 5. Now search (CTRL + F) for the following tag:
    </body>
    Step 6. And just above it, paste the code below:
    <script src='http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js' type='text/javascript'/>

    <div class='button_up' id='button_up' style='display:none;'/>
    <div class='button_down' id='button_down' style='display:none;'/>

    <script>
    //<![CDATA[
    (function(){var special=jQuery.event.special,uid1='D'+(+new Date()),uid2='D'+(+new Date()+1);special.scrollstart={setup:function(){var timer,handler=function(evt){var _self=this,_args=arguments;if(timer){clearTimeout(timer)}else{evt.type='scrollstart';jQuery.event.handle.apply(_self,_args)}timer=setTimeout(function(){timer=null},special.scrollstop.latency)};jQuery(this).bind('scroll',handler).data(uid1,handler)},teardown:function(){jQuery(this).unbind('scroll',jQuery(this).data(uid1))}};special.scrollstop={latency:300,setup:function(){var timer,handler=function(evt){var _self=this,_args=arguments;if(timer){clearTimeout(timer)}timer=setTimeout(function(){timer=null;evt.type='scrollstop';jQuery.event.handle.apply(_self,_args)},special.scrollstop.latency)};jQuery(this).bind('scroll',handler).data(uid2,handler)},teardown:function(){jQuery(this).unbind('scroll',jQuery(this).data(uid2))}}})();

    $(function() {
    var $elem = $('body');
    $('#button_up').fadeIn('slow');
    $('#button_down').fadeIn('slow');
    $(window).bind('scrollstart', function(){
    $('#button_up,#button_down').stop().animate({'opacity':'0.2'});
    });
    $(window).bind('scrollstop', function(){
    $('#button_up,#button_down').stop().animate({'opacity':'1'});
    });
    $('#button_down').click(
    function (e) {
    $('html, body').animate({scrollTop: $elem.height()}, 800);
    } );
    $('#button_up').click(
    function (e) {
    $('html, body').animate({scrollTop: '0px'}, 800);
    } );});
    //]]>
    </script>

    Note: In case you want to remove the "Go to top" button, remove the 1st bolded code and to remove the "Go to bottom" button, remove the 2nd one.

    Step 7. Finally, Save your changes by clicking on the Save template button. Enjoy!
