terminal - grep recursively for a specific file type on Linux

Question

Can we search a term (eg. "onblur") recursively in some folders only in specific files (html files)?

grep -Rin "onblur" *.html

This returns nothing. But,

grep -Rin "onblur" .

returns "onblur" search result from all available files, like in text(".txt"), .mako, .jinja etc.
