No.
Part by part...
PDF is a self-contained file that includes the page layout, fonts, tags, graphics, and all other information required for the appearance.
Originally used PostScript page description programming language to do this, PDF now uses its own PostScript-like encoding. This "nails down" the appearance at the time the PDF is created from the source file. There's nothing left to anyone's interpretation or rendering. It is a hardwired file, which is why it's used in enterprises that need to record the data at a specific time.

Originally intended for the printing and graphics arts community which needed a way to move a design/layout from the designer's computer to the print shop's computer so that it could be printed. That's why it's locked down. Nothing should move, rewrap, or change as the file moves from one computer to the other.

There are no styles in a PDF.
So there isn't anything to apply to anything to create the presentation.

Not at all like HTML! To me, they are the exact opposites of each other.
