How to Create a Floating "Sticky" Sidebar Widget in Blogger
Remember: This works pretty well with all kinds of widgets
present in your sidebar. It is not necessary that a person can only use
if for email subscription boxes. You can use it for promotion of your
items, galleries, popular posts, Instagram photos, and basically everything that you wish for.
Step#1: Adding a New Widget:
The First thing you need to do is to add a new widget in your sidebar so that later on you can make it sticky. Go to Blogger.com >> Layout >> Add a Gadget >> Add HTML/JavaScript >> and name the widget as “My Sticky Gadget”. Now writing anything in the HTML body and once everything is down press “Save” button located at the end of the page.Step#2: Installing a “Sticky” Plugin:
Now after properly adding a new widget in your blog, it’s time for some serious work. This time go to Template >> Edit HTML >> and search for the ending </body> tag and just above it paste the following JavaScript code.<script>

// Author: Syed Faizan Ali
(function($) {
var defaults = {
topSpacing: 0,
bottomSpacing: 0,
className: 'is-sticky',
center: false
},
$window = $(window),
$document = $(document),
sticked = [],
windowHeight = $window.height(),
scroller = function() {
var scrollTop = $window.scrollTop(),
documentHeight = $document.height(),
dwh = documentHeight - windowHeight,
extra = (scrollTop > dwh) ? dwh - scrollTop : 0;
for (var i = 0; i < sticked.length; i++) {
var s = sticked[i],
elementTop = s.stickyWrapper.offset().top,
etse = elementTop - s.topSpacing - extra;
if (scrollTop <= etse) {
if (s.currentTop !== null) {
s.stickyElement.css('position', '').css('top', '').removeClass(s.className);
s.currentTop = null;
}
}
else {
var newTop = documentHeight - s.elementHeight - s.topSpacing - s.bottomSpacing - scrollTop - extra;
if (newTop < 0) {
newTop = newTop + s.topSpacing;
} else {
newTop = s.topSpacing;
}
if (s.currentTop != newTop) {
s.stickyElement.css('position', 'fixed').css('top', newTop).addClass(s.className);
s.currentTop = newTop;
}
}
}
},
resizer = function() {
windowHeight = $window.height();
};
// should be more efficient than using $window.scroll(scroller) and $window.resize(resizer):
if (window.addEventListener) {
window.addEventListener('scroll', scroller, false);
window.addEventListener('resize', resizer, false);
} else if (window.attachEvent) {
window.attachEvent('onscroll', scroller);
window.attachEvent('onresize', resizer);
}
$.fn.sticky = function(options) {
var o = $.extend(defaults, options);
return this.each(function() {
var stickyElement = $(this);
if (o.center)
var centerElement = "margin-left:auto;margin-right:auto;";
stickyId = stickyElement.attr('id');
stickyElement
.wrapAll('<div id="' + stickyId + 'StickyWrapper" style="' + centerElement + '"></div>')
.css('width', stickyElement.width());
var elementHeight = stickyElement.outerHeight(),
stickyWrapper = stickyElement.parent();
stickyWrapper
.css('width', stickyElement.outerWidth())
.css('height', elementHeight)
.css('clear', stickyElement.css('clear'));
sticked.push({
topSpacing: o.topSpacing,
bottomSpacing: o.bottomSpacing,
stickyElement: stickyElement,
currentTop: null,
stickyWrapper: stickyWrapper,
elementHeight: elementHeight,
className: o.className
});
});
};
})(jQuery);

<script type='text/javascript'>
$(document).ready(function(){
$("#mblfloater").sticky({topSpacing:0});
});
</script>
Step#3: Creating a Widget “Sticky” in Blogger:
After adding the JavaScript code, you have to search for the name of your widget. Since, we have named it as "My Sticky Gadget". Therefore, in the template coding search for "My Sticky Gadget". To be able to search correctly it is essential that you must use the built-in search box provided by the Blogger template editor.Note: To enable the search box click anywhere in the template editor and press "CTRL+F". Now on finding "My Sticky Gadget" you will able to see a code similar to the the following one.
<b:widget id='HTML32' locked='false' title='My Sticky Gadget' type='HTML'>
<b:includable id='main'>
<!-- only display title if it's non-empty -->
<b:if cond='data:title != ""'>
<h2 class='title'><data:title/></h2>
</b:if>
<div class='widget-content'>
<data:content/>
</div>
</b:includable>
</b:widget>
Now after finding the code as mentioned above, just replace it completely with the following coding.
<b:widget id='HTML32' locked='false' title='My Sticky Gadget' type='HTML'>
<b:includable id='main'>
<div id='mblfloater'>
<!-- only display title if it's non-empty -->
<b:if cond='data:title != ""'>
<h2 class='title'><data:title/></h2>
</b:if>
<div class='widget-content'>
<data:content/>
</div> </div>
</b:includable>
</b:widget>
Remember: The ID of your widget should be unique. For example, if you are using id='HTML32' in any of your widget then you cannot use the same ID for others.
All done: Once everything is done, press the "Save Template" button to finish the process.
