Purple Numbers Are Just HTML

Purple numbers are just regular HTML. There's absolutely nothing special about the HTML for displaying purple numbers.

The "purpleness" of purple numbers is just a convention. If you look at the bootstrap.org web site, many of the "purple" numbers on the site are not actually purple.

Here's a sample HTML paragraph with a purple number:

    <p><a name="nid027">
    These are the days that try men's souls. &nbsp;&nbsp;
    <a href="#nid027">(027)</a></p>

In this example, the "purple" number is displayed in the color the browser uses for links. The color can be changed using a CSS stylesheet. Also, note that the number itself is a live link, making it easy to copy and paste the URL that points to the paragraph with that purple number.
