Adding grid for blogs in "Blog" page

**Is your feature request related to a problem? Please describe.**
Adding a grid of 4 blog posts in each row will make it easier for the user to navigate and look through the entire blog page. Currently, there are 2 blogs in each row and that makes the user scroll a lot to land to their desired/end of the blog page. Adding 4 blogs in each row will be easier for the user to take a glance at all the blogs and make a choice more easily of which blog he wants to see.
