I often find it confusing using something at the end of the sentence or title that describes a list or content below it.

The sentence example:

Here is the list of services we provide (':', '--' or '-'?)
[The list of services here]

The title example:

Enterprise mobility (':', '--' or '-'?)
[The enterprise mobility content here]

Note: While describing the 'sentence example' and 'title example', I used colons above.

    A colon is your best bet, imo. :) Feb 11 '14 at 9:51
  • there is other option: no punctuation

  • @Theta30 I may not fully agree with that in case of sentence However, it's good escape for titles!

One of the primary purposes of colons is to indicate to the reader that what follows either more fully explains a previous thought or, quite specifically, is an enumeration (listing) of related things. See the usage section on Wikipedia's article on the colon for more details and examples that at least Wikipedia's community finds acceptable.

As for titles, sometimes you may see an em-dash used to separate a primary title from a subtitle, but generally title and subtitle are separated by a line break (e.g., on the title page of a book) or by a colon (e.g., The Omnivore’s Dilemma: A Natural History of Four Meals, taken from these examples of Chicago-style citation).
