Simple, dependency free javascript modal

simple-modal is a tiny javascript and CSS modal library. It works very similarly to Bootstrap modals, without the need for jQuery or Bootstrap. In fact, simple-modal can be swapped out with Bootstrap modals without making any changes to your markup.

simple-modal exposes a single global method, modal(), that can be used to launch modals with JavaScript. However, the primary means of using simple-modal is through the use of HTML classes and attributes.


  • Dependency free, no jQuery or Bootstrap

  • Tiny

    • JS compressed, gzipped - 534 bytes
    • CSS compressed, gzipped - 593 bytes
  • Responsive sizing

    • Modal size responds to viewport size
    • Modals never extend outside the viewport
  • Optional size classes

    • modal-sm
    • modal-md
    • modal-lg
    • modal-xl
  • Click delegation

    • Modals and buttons that are dynamically created will still work
  • Swappable with Bootstrap

    • simple-modal uses the same class names and modal() method as Bootstrap, making it super simple to swap out as your project grows
