I like that it's lightweight, easy to use in your front-end design projects with bootstrap or just using plain HTML elements. It can be used along side other more complex UI frameworks such as Foundation 5 / Zurb. There are some nice tutorials available online but not too many compared to others. Maybe try out Bootstrap first before jumping into this one? The documentation is pretty good here (at least there isn't much missing). This could help you figure stuff out if something goes wrong when trying to get set up. You want simple yet robust layout controls like columns & rows while making things responsive so they look great across all devices sizes without having to do extra work after deployment.
