HTML5 Videos are a convenient and effective way to display videos on any website. In fact, Divi uses the HTML5 video format to display videos in Divi using the Video Module. However, by default, these videos contain built-in controls (like play, mute, volume, etc.) that have a standard design that is dependent on your browser. But, if you want to enhance the design of these controls, you can actually build and style your own external controls for your HTML5 video.
