The CSS element.class that appeared in a file, gathered through
html_attribute_class calls (see Formatting HTML Element with Classes) are available through the html_get_css_elements_classes
function:
\@css_element_classes = $converter->html_get_css_elements_classes ($file_name) ¶Returns a reference on an array containing element.class pairs of elements
and classes appearing in $file_name.
It is possible to change completely how CSS lines are generated by redefining the following function reference:
$css_lines format_css_lines ($converter, $file_name) ¶This function returns the CSS lines and <script> HTML element
for $file_name.
In the default case, the function reference uses CSS_REFS corresponding
to command-line --css-ref, html_get_css_elements_classes,
css_get_info and css_element_class_rule
(see Customization of CSS Rules, Imports and Selectors) to determine the
CSS lines.
