Ever since Pinterest entered the scene, it seems every website is never complete unless it has a grid of something in it. It could be a grid of photos, posts, ads, social share buttons… frogs, anvils. Just put a grid on it! All kidding aside, grids are a really modern and intuitive way to present a lot of content to your users so they can get to various destinations of your site easily. Add something like masonry.js or isotope.js and now you’ve got a filterable and sortable grid to boot.
