html can you add a style to a class to tell it to reset code example

Example 1: how do i set a pdf to be download link in html

<a href="./directory/yourfile.pdf" download="newfilename">Download the pdf</a>

Example 2: how can i make a quote element in html

<p>Anything you'd like to mention goes here: <blockquote>"Insert actual quote here."</blockquote> - Mr. Name</p>

Example 3: how to make comments in markdown which do not render in html

[//] <> (This works, parathesis are necessary btw)
[//] # (This is perhaps the most platform independent solution.
In either case, the comments will not render to html,
even if the user selects view source.)
