Comment

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The Comment interface represents textual notations within markup; although it is generally not visually shown, such comments are available to be read in the source view.

Comments are represented in HTML and XML as content between <!-- and -->. In XML, like inside SVG or MathML markup, the character sequence -- cannot be used within a comment.
