How to create a single page pdf from a html file

I'm currently using the convert-html-to-pdf library (version: 1.0.1) to convert html files into pdf. But, the conversion is separating my html in multiple pages and it ends up breaking the code (streched divs).

Since my html file is responsive to certain needs, the size of the div blocks change on each file, and because of this I'm not able to determine when to "break" each page unless I somehow measure the size of the page and the size of the blocks. There are two possible corrections:

• create a single page pdf (this one is preferred)
• mesaure the size of the page and compare with the items to make sure they are not separeted each page

The first one is supposed to be easier, but I can't find anything in the documentation that helps me do that.

I'm inclined to accept libraries suggestions to create a single page pdf.
