.SYNOPSIS
    HTML Elements
.DESCRIPTION
    HTML Elements Cheat Sheet
.NOTES
    It's nice to have a handy reference of HTML elements.

    I'd highly recommend using the [Mozilla Developer Network](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/).

    In case you ever want to get all of the elements in a PowerShell script, this page shows you how.

    It extracts all of the reference links and outputs them into a handy table and a json file.
