Minimal HTML5 Video Player With Pure JavaScript

A minimal, Vanilla JavaScript-based HTML5 video player with custom controls styled with your own CSS.

How to use it:

Embed an HTML5 video with player controls into the page.

<div class="player">
  <video class="player__video viewer" src="mov.mp4"></video>
  <div class="player__controls">
    <div class="progress">
      <div class="progress__filled"></div>
    </div>
    <button class="player__button toggle" title="Toggle Play">►</button>
    <input type="range" name="volume" class="player__slider" min="0" max="1" step="0.05" value="1">
    <input type="range" name="playbackRate" class="player__slider" min="0.5" max="2" step="0.1" value="1">
    <button data-skip="-10" class="player__button">« 10s</button>
    <button data-skip="25" class="player__button">25s »</button>
  </div>
</div>

Load the main player JavaScript at the end of the page.

<script src="js/index.js"></script>
