 Custom link styles
 ------------------
 If you want a specific style to be applied to code block links,
 you may add your own CSS file to the Sphinx build.
-All code block links use the ``sphinx-codeautolink-a`` class.
-For example, you can add dotted lines to all links and change the hover colour:
 
 .. code:: python
 
    # conf.py
    html_static_path = ['static']
    html_css_files = ['custom.css']
 
+To include only in specific documents, see the ``html-page-context`` event
+and the :meth:`Sphinx.add_css_file` function.
+For example, you can add similar underlines as this documentation
+and change the hover colour:
+
 .. code:: css
 
    /* static/custom.css */
    .sphinx-codeautolink-a{
-       border-bottom-color: rgb(0, 0, 0);

 CSS class
 ---------
 The CSS class used in all code block links is ``sphinx-codeautolink-a``.
+By default, the links only have a light blue hover colour.
+The style has been made more obvious in the documentation for demonstration.
