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”

I guess you mean the sub-heading.

Headlines and subs are NOT punctuated except for colons, thus

“Miller to Unions : Drop Dead”
