Does the Line Under the Newspaper Headline Need to End in a Period?

Question by Eggggpie: Does the line under the newspaper headline need to end in a period?
It is not common that you would see a line under the headline of a newspaper that explains a little further of what the content of the article is about. However, I must include one in my article for an English assignment but I’m not sure whether I need to end it off with a period or not:

“Transplant recipient dies from liver failure after alcohol abuse”

Best answer:

Answer by rejectedzipper
I guess you mean the sub-heading.

Headlines and subs are NOT punctuated except for colons, thus

“Miller to Unions : Drop Dead”

Answer by checkmate
It depends on the house style that usually does eschew punctuation to convey an atmosphere of immediacy but a sentence should begin with a capital letter and end in a full stop (period to Americans and Scots of a certain age).
