Improve design of blog home page and blog category page

[yemisi-o]

This is to redesign the blog's home page and category page to be more user-friendly and mobile responsive. The current design is not well done and is not optimised for readability. You can make changes at your discretion but some of the changes I think may be needed are listed below:

• Blog's home page changes: The most viewed article should be displayed at the landing section in place of the current image there. Images for posts listing shouldn't be circular, maybe a square or rounded rectangle
• Blog's category page changes: Any changes made for the posts listing will also apply here but the category name should still be maintained here
• Modify blog's navigation: The blog's navigation should be modified to include available blog categories (the categories are currently in a sidebar). Please note that categories can get much past the navbar and it is important the design caters for this (maybe by using a dropdown or by creating a subnav for categories seperate from the main nav).
