html or htm,htm vs. html,What is the difference between the HTM and HTML extensions

html or htm,htm vs. html,What is the difference between the HTM and HTML extensions



Other then the obvious, the letter "L," there's not much of a difference between the two extensions. Most, if not all, web browsers and servers will treat a file with an HTM extension exactly as it would a file with an HTML extension, and vice versa. 


Practical Differences
Practically speaking, there is no difference between the two extensions. Both denote that the file contains HTML. This is really a matter of convention and is not an absolute, but most realize that a file whose extension is htm or html contains HTML.
