A Few Practical Notes on HTML

Points Worth Knowing

HTML5 introduced elements like <video> and <audio>, removing the need for plugins like Flash for media playback.
HTML input types like email or date give browsers basic built-in validation, without needing any JavaScript.
HTML's tree structure, the DOM, is the foundation every frontend framework — React, Vue, and others — is ultimately built on top of.

None of these points are complicated on their own, but knowing them can lead to better technical decisions about HTML on your next project.
