.htm any different from .html?

Ok, this sounds very stupid but I have downloaded several pre-made templates and have found that most of them use the file extension .htm

I'm also worried some browsers may not support or display .htm properly :/

They both mean a html file.
the reason that there is two, is that seriously old computers only supported 3 letters in the file extension. Now that is no longer a problem, but people just haven't moved on.
So just use whatever is easiest for you - some editors make .htm files by default, some .html. Just don't waste your time going round changing them all...

Ok, thanks for the help :D

Its the same pal.. The reason there was a .htm is because a little while back you couldnt have 4 letter extentions.. Exactly the same.. no difference.. but, you can still use .htm if you chose.
