If you want to check out my code on jsfiddle and learn how to create a style similar to Pinterest without using plugins, click on the link below. Within the code, there is a square Node.js diagram that I would like to position down the left side.

Although there are plugins and frameworks available to achieve this layout, such as Gumby Framework and Masonry, I prefer to keep it simple and create this look without relying on external tools.
