Equivalent of include() in HTML

Question

I was wondering wether there is a way to include some html content inside another html using only html?

A replacement to PHP\'s

Answer 1

The lack of Include\Import in Html is really frustrating!

A good alternative is "Server Side Includes (SSI)" in case "PHP" is not supported!

SSI is supported by almost any (if not all) web host server!

The file that contains the above line must end with ".shtml" or ".shtm" extensions!

It's really annoying that something as easy as Include\Import can't be performed by the browser itself!

Like php or Node.js, preprocessing the html using Javascript itself before the HTML Load process start should be supported in any browser!
