In Blogger we have option to set the number of posts we want to display per page by going to Settings menu. Once the number of posts in our blog exceeds this number, we will see "Older Posts" and "Newer Posts" navigation links in our home page and archive pages footer as Blogger doesn't have any built in function on page numbering. But page numbers instead of older and newer posts links could help our blog visitors to navigate quicker and know the total number of posts published.
So this tutorial will show you how to add numbered page navigation using javascript to a Blogger/Blogspot blog.
Adding Numeric Page Navigation To Blogger
You can add this widget in just two steps :
- Adding The CSS.
- Adding The Script
Now let's see how to add the CSS style for Page navigation.
1. Adding The CSS
Step 1. Go to Blogger Dashboard > Theme > "Edit HTML"
Step 2. Click anywhere inside the code area and press the CTRL + F keys to open the Blogger Search Box.
type or paste the following code inside the search box and hit enter to find it :
]]></b:skin>Step 3. Now copy the below code and just above ]]></b:skin> paste the code.
#blog-pager{clear:both;margin:30px auto;text-align:center; padding: 7px;}.blog-pager {background: none;}.displaypageNum a,.showpage a,.pagecurrent{font-size: 14px;padding: 5px 12px;margin-right:5px; color: #666; background-color:#eee;}.displaypageNum a:hover,.showpage a:hover, .pagecurrent{background:#359BED;text-decoration:none;color: #fff;}#blog-pager .pagecurrent{font-weight:bold;color: #fff;background:#359BED;} .showpageOf{display:none!important}#blog-pager .pages{border:none;}Note: If you want to hide the "First" and "Last" buttons add this line below CSS code :
.firstpage, .lastpage {display: none;}2. Adding The Script
Step 4. Now Find below tag.
</body>Step 5. Add the following script just above </body>
<b:if cond='data:blog.pageType != "item"'><b:if cond='data:blog.pageType != "static_page"'><script type='text/javascript'> /*<![CDATA[*/ var perPage=3; var numPages=3; var firstText ='First'; var lastText ='Last'; var prevText ='« Previous'; var nextText ='Next »'; var urlactivepage=location.href; var home_page="/";

after installing you might want to change these default settings :perPage: 7,numPages: 6,var firstText ='First';var lastText ='Last';var prevText ='« Previous';var nextText ='Next »';}1. perPage: and numPages: change with your desired number.
2. To replace the 'First'; Last'; '« Previous'; Next »'; texts, just type your own within the quotes.
Label Fix :
By default, Blogger will show 20 posts on label pages. To make this widget appear on label pages, we will have to cut down this to the value that we gave for the perPage variable.
Find each occurence of the following code snippet :
expr:href='data:label.url'Replace it with the one below :
expr:href='data:label.url + "?&max-results=7"' Here 7 is the number of posts that will be displayed per page.
Step 8. Click on "Save Button" . Successfully added numeric pagination.
