Answer 1

You can't do it. But you can use custom Alert and Confirm boxes.

You can read about some User Interface libraries here:

Most common libraries are:

• http://jqueryui.com/
• http://mootools.net/
• http://www.prototype-ui.com/
• http://script.aculo.us/
• http://developer.yahoo.com/yui/

Answer 2

Maybe you coul'd use UTF8 bold chars.

For examples: https://yaytext.com/bold-italic/

It works on Chromium 80.0, I don't know on other browsers...

Answer 3

The alert() dialog is not rendered in HTML, and thus the HTML you have embedded is meaningless.

You'd need to use a custom modal to achieve that.
