Named after the greatest grid system in the world, Manhattan is a clean, lightweight and customisable CSS grid. It uses it's own data-attribute mhtn keeping your class markup clean.

It offers three containers, the default restricts content on screens over a specified width, whereas flex and edge allow you to maximize any screen.

Manhattan doesn't use a traditional 12 column layout, but instead opts for straight forward percentages. There are five breakpoints for total control over your layout, where you can specify a width for each column at each screen size.

Manhattan supports all modern browsers and most older ones, including IE 8 with the help of a media query polyfill.


There is no shortage of CSS grids available and with so many frameworks offering everything you need, it can be hard to know which use, or if any. Pre-styled and assembled from components, I see too many websites lacking creativity and imagination. Although a grid isn't necessary either, it can be a useful tool for speeding up development without interrupting your website's personality.

I struggled to find a flexible grid without a heavy footprint, so I created Manhattan. It's ultra light, weighing in at 2.8 kb minified/658 bytes gzipped and released under the MIT license, free to use and abuse.


Take a look at the Manhattan website for demos and usage docs.
