Material design says to skip periods for messages in dialogs which are only one sentence. Yet in their dialog examples they use a period in that circumstance. So, which is it?

  • It says "Any sentence followed by a link (links themselves should not be full sentences)" The example has links following it. Is that what you're talking about? Miss it?

  • No, it's in the "Skip unnecessary punctuation" section.

  • Yeah, that's from the Skip Unnecessary Punctuation section: "Use periods on: Multiple sentences Any sentence followed by a link (links themselves should not be full sentences)"

You are right that most of the examples on that dialog page ignore the punctuation rule. It could be outdated examples. That page however doesn't address punctuation so I would follow the rules described on the page about writing. There is stated:

Avoid using periods on solitary sentences within these UI elements:

A funny fact is that "Dialog" in that text is a link that refers to the top of the dialog page where the first example is the only right example.

Later the page about writing refers to a different section of the dialog page. (the one referred to by the OP). From there you only see the "wrong" (lets assume outdated) examples.

The following components have specific writing guidance:


If you mean this, here are two sentences: Reset settings? and This will reset...

I assume that the rule is exclusive to single sentences:

  • "Reset settings" is a header. I really don't think they mean to include headings when talking about single vs multiple sentences.
