drupal_add_css($path = NULL, $type = 'module', $media = 'all', $preprocess = TRUE)
Adds a CSS file to the stylesheet queue.
What does this actually mean? CSS preprocessing is the process of aggregating a bunch of separate CSS files into one file that is then compressed by removing all extraneous white space.
The reason for merging the CSS files is outlined quite thoroughly here: http://www.die.net/musings/page_load_time/
'Load fewer external objects. Due to request overhead, one bigger file
just loads faster than two smaller ones half its size.'
However, you should *not* preprocess every file as this can lead to
redundant caches. You should set $preprocess
= FALSE
when:
- Your styles are only used rarely on the site. This could be a special admin page, the homepage, or a handful of pages that does not represent the majority of the pages on your site.
