 `hint.css` is written as a pure CSS resource using which you can create cool accessible tooltips for your web app. It does not rely on JavaScript but rather uses **aria-label**/**data-* attribute**, **pseudo elements**, **content property** and **CSS3 transitions** to create the tooltips. Also it uses **BEM** naming convention particularly for the modifiers.
