Mini pager need to be styled

Problem/Motivation

While going through the theme for issues I found out that the mini pager is not styled. Attaching the screenshot for a better understanding and making the issue clearer.

Steps to reproduce

Install the theme
Add 10-20 articles and check for the pagination.
Go to the page view setting and change the pager to mini.

Proposed resolution

The mini pager should be styled in the same style as the full pager. Apply the changes from the parent issue before working on this issue.
