For the design I decided to go with a clean modern feel that contained plenty of white space and used an appeasing color palette.
I added a "back to the top" link for ease of use and also the option for the user to load more articles for endless reading. There is a hover change on articles to provide visual feedback and useful information included like publication date and category to help the user visually filter articles they might be interested in.
The responsive grid adjusts the number of columns based on the size of the screen, while keeping the width of articles at a fixed width regardless of screen size. The rows of articles are cleared so that they are at a uniform height across the top edge.
