Tingle uses just one small CSS. Feel free to include it in your workflow (Less, Sass, etc...) and customize it to fit your needs. <link rel="stylesheet" href="tingle.min.css"> Then, just include tingle in your document: <script src="tingle.min.js"></script> Use // instanciate new modal var modal = new tingle.modal({ footer: true, stickyFooter: false, closeMethods: ['overlay', 'button', 'escape'],
