Font size not applying correctly

[tomcashman]

I have a use case where I require the cover page to include a product name and document name. Unfortunately, when I put them in the title the string is too long and the wrapping is wrong.

I've attempted to change the font size using the following values:
36
"36"
"36px"

but none seem to work when I export the PDF.

Alternatively, it may be good to add a subtitle option or support for line breaks?

I like the idea for the subtitle, could you be able to send a pull-request? :-)

I think it's better to call it "description", since it's how it's called the field on Gitbook.io and this way it can be used the description field in the package.json by default.
