A note about the CSS

This module adds a CSS file that is only a few lines in length. You may choose
to move this CSS to your theme to prevent the file from needing to be loaded
separately. To do this:

  1. Open the .info file for your theme and add this line of code to prevent the
    extlink.css file from loading:
    stylesheets[all][] = extlink.css

  2. Copy all the code from this module's css/extlink.css file into your theme's
    CSS file.

  3. Copy the images/extlink.png and images/mailto.png files to your theme's

Note that you DO NOT need to make an extlink.css file in your theme.
Specifying the file in your theme's .info file is enough to tell Backdrop not
to load this module's version of the CSS.
