jQuery is the most popular JavaScript library available today. With its features, jQuery has changed the way that millions of people write JavaScript. To use jquery, we need to host "jquery.min.js" file in our server or we can use a CDN like Google Hosted Libraries. But if you do not need to host jQuery as a external file, follow the steps below:

1.Login to your Blogger account and go to "Edit HTML" of your blog.

2.Scroll down to where you see this (or use Ctrl+F to find that code):

</b:skin>

3.Copy this code and paste it just after the </b:skin> tag .

4.Now save your template.
