Foundation vs. Skeleton

Great starting point for prototypes and sometimes full sites.

I use foundation only for the grid, i create my own other components

Foundation with Rails application

Front end development/styling.

Used Foundation as responsive grid system

Foundation makes our web based applications responsive.

There's a grid in there somewhere...

My front-end framework of choice. Foundation is super-simple to use for just about anything, and directs my focus always on mobile-first.

CSS framework used in the new version of the App

UI layouts

Provide basic CSS styles.

Foundation has been my choice for years over Bootstrap and other similar CSS frameworks due to the naming conventions, well-designed built-in components, and it plays well with React when I'm not using ElementalUI instead.

I use it for a lot of professional work where I might need more than just a responsive grid. Has a great set of mixins and components and also some nice JS-modules. I love that its so style-agnostic. Really easy to add custom styling.

My favorite, no-frills, base responsive CSS grid.

I used it for some private stuff lately where I only needed a grid and was looking for the leanest framework there is.

Like Bootstrap, It offers the same CSS framework service (Which I prefer to say cheatsheet ;)) but less complex and cleaner look and to the point.
