ummm actually there is sort of a way of doing it using software which 'encrypts' the source like :

this turns the HTML into a non-human readable form making it harder for people to rip off your code. Your browser can still read/render it - but your average person will not be able to read it. Making it difficult for them to take/re-use your code.

not a ideal solution but def a hinderance
