However, avoid adding blank lines between any lines that begin with wikitext symbols for lists, because this increases the complexity of the generated HTML code and creates accessibility problems. These symbols include: asterisks (*), which make bulleted lists; hash symbols (#), which make numbered lists; semi-colons (;), which make the first half of an HTML association list (rendered as bold-faced text); and colons (:), which make the second half of an HTML association list, but which are popularly used for the resulting visual indentation effect.
