Native JavaScript Equivalents of jQuery Methods: the DOM and Forms

Native JavaScript Equivalents of jQuery Methods: the DOM and Forms

Core points jQuery is a useful tool for developers who need to support legacy Internet Explorer or write libraries like jQuery longer than developing applications.

Accessible Audio Descriptions for HTML5 Video

Accessible Audio Descriptions for HTML5 Video

Summary of key points Traditional visually impaired audio descriptions require professional video editing equipment to be encoded and embedded in separate audio tracks of video files. This process is often unrealistic for most content creators. The HTML5 video specification provides an audioTracks object that theoretically allows the implementation of switch buttons for audio descriptions and controls the audio and video volumes separately. However, browsers currently have limited support for this feature. Another solution is to use MediaController, a feature of HTML5 audio and video that allows syncing multiple sources. This feature is currently limited in browser support, but it can be used to launch two media simultaneously using existing, widely implemented features
