Hey friends, today in this blog you'll learn how to create Fully Functional Pagination Design using HTML CSS & JavaScript. In the earlier blog, I've also shared many <a href="https://www.codingnepalweb.com/search?q=pagination">pagination designs</a> but these paginations are not functional and these were created only for design purposes. Now I'm going to create a fully functional and easy to navigate pagination in JavaScript. 

You may know, Pagination is a method or process of dividing the web pages, or a section of content into discrete/many pages. Pagination plays an important role in the SEO (Search Engine Optimization) of your website and it is also important and most used in web design. 

In this design [Pagination UI Design], there is a pagination with the previous and next button and some numbers. I already told you, this is fully functional pagination so when you click on the next or previous button, the number of the pagination also changed accordingly. There is a total of 20 pages or numbers but you can easily add more according to your web pages.

You can copy the codes from the given boxes or download the code files from the given link but I recommend you to download the source code files instead of copying codes. <a href="https://www.codingnepalweb.com/2020/12/pagination-ui-design-using-html-css-javascript.html">Click here to download code files.</a>
