Hi @awickham10

Thanks a lot for your PR ! It is perfect!

Could ask you one very small change before merging it?

I noticed the help is still the one for the "

" element

<#
    .SYNOPSIS
    Generates em HTML tag.
     .Description
    This tag is a "Textual semantic" tag. To use it in a "P" tag, be sure to prefix it with a semicolon (";").
    See example for more details.
     .EXAMPLE
    p{
        "This is";em {"cool"}
    }
     Will generate the following code
     <p>
        This is
        <em>
        cool
        </em>
    </p>

You can find infos here to update it accordingly:

This should be done in not time.

Keep them comming 👍 !

Is this more what you were thinking?

    .SYNOPSIS
    Generates em HTML tag.

    .Description
    This tag is a phrase tag. It renders as emphasized text.

    .EXAMPLE
    p{
        "This is";em {"cool"}
    }

    Will generate the following code

    <p>
        This is
        <em>
        cool
        </em>
    </p>

Yeah, that is great!
One very last thing, and then I'll merge: Could you change the $Content parameter from mandatory=$true to $false?

I think we should leave the possibility for the end user to set an em element with an empty value. (and modified using Javascript in a later step for example).
Thanks!

Done!
