Usign dots in files names

HTML & CSS
1

Hi there,

Is it ok to use dots within an HTML file extension. For example: hello.index.html? or a.index.html?

Thanks!

I don’t remember if that’s valid or not. For PHP certainly, for plain HTML… can’t tell right now.

Anyway, HTTP or not, I never use a symbol that may mean something for the Operative System, and the dot is meaningful to any OS.

So I would name them a_index.html.
