Grid Critters

Master CSS Grids, Save the Critters

Building modern layouts with CSS can be a real challenge. Even the most simple UI can be a struggle. From a div randomly not lining up - to everything looking completely broken on mobile - CSS can make even the smartest devs want to pull out each strand of hair one at a time with tweezers. Why does creating great looking UI's have to be so painful?

What if you could master a futuristic layout technology that's 10x more powerful and 10x more reliable, to build amazing apps and sites with crazy confidence and speed? You absolutely can. The future of layout is here and it's called CSS Grid.
