See Simple Customization of CSS Rules and Imports for information on CSS customization.
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 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 and
css_get_info (see Simple Customization of CSS Rules and Imports) to determine the CSS
lines.
