Help with creating a 3-column image grid

I am a bit rusty here lately, and I am pretty well clueless as how to go about what I aim to accomplish.

Here is a template screen-cap of what I am attempting to code: Example 01

How can I get my posts to appear in this manner (with slider-transition in the pagination if possible, please.)

A great example of a site that has accomplished the grid with slider-like transition for pagination can be seen here: https://beautylish.com

Thanks for any help, it is greatly appreciated!
