StyleTester is a Kirby CMS theme for creating Style Guides. You can use the StyleTester back-end to create, organize and comment html elements that will be rendered using your CSS and JS files. The StyleTester front-end will present these elements with comments, code snippets and all the controls you need to present them.
You can use the same StyleTester install to house various Style Guides and if you wish share CSS and JS files among them. View the StyleTester here.
