How does the definition list differ from the ordered and unordered lists?

Answer 1

Ordered lists are numbered or lettered. Unordered lists usually have some form of bullet points. Both types of lists are straight lists, with all items having equal importance. A definition list allows you to have a main list with sub lists in it. So for example you could use a definition list to show Oscar categories and nominees. The main list would be the categories. For each category there would be a smaller list with the nominees. Those items would be pushed further in from the edge of the screen. You could have a list of teams and the players for each team. You could have a list countries and some of the cities for each one. So any list that has main headings and a list for each heading can be done with a definition list. It has 3 tags dl, dt and dd. dl starts a list and ends it. dt is for the main list items. dd is for the sub-list items. For example:

Item 1

sub item 1a

sub item 1b

sub item 1c

Item 2

sub item 2a

sub item 2b

sub item 2c

Item 3

sub item 3a

sub item 3b

sub item 3c
