Garden is a css library created based on Leroy Merlin’s needs, and used internally as well.
Garden also relies on jQuery to provide API standards for it’s components. Please take note Garden does not comes with jQuery, allowing you to use your own version based on your needs. You can opt for Zepto, for example. Or a custom build of jQuery as well.
Garden CSS/JS components targets all major browsers, including IE9+. CSS prefixors are added through Autoprefixer.
Be sure to checkout the Getting Started section for more info on how to use Garden.
