What does <! - - comment - - > do?

Question

I still don't get it. Can someone explain it more?

Answer 1

It simply does nothing, it is to make code easier to read.

Example:

<svg height="100" width="100">
<circle cx="50" cy="50" r="40" stroke="black" stroke-width="3" fill="red" />
Sorry, your browser does not support inline SVG.
</svg> <! -- draws a red circle with black outline-->
