How do I code a BTN in an HTML project to open a users email client
<p>I am new to HTML and CSS and trying to  build something which resembles a homepage.</p>

<p>Please see screenshot.</p>

<p>As you can see, I have a couple of bootstrap buttons deployed in the Jumbotron. I would like these BTN's when clicked to open up the users email client in the form of a mailto action in a target blank.</p>

<p>I would be grateful to know how to code this please. </p>
