Is it normal to store large pieces of HTML-code in properties file?

Is it normal to store large pieces of HTML-code in properties file?

I need to store a quietly big piece of HTML-code as a static resource. Is
it normal to put it into properties file? Or would it be better if it
stored in separate HTML-file? Storing in properties file seems to be more
convenient since Spring has build-in mechanism to work with it, but I'm
not sure this is a good approach.
Thanks.
