Plane HTML cannot do this... You could use SSI (server side include) or PHP... Here is a SSI Tutorial http://http-server.carleton.ca/~dmcfet/html/ssi.html Code (markup):
AH! But you CAN include HTML inside HTML! And not with that SSI .htaccess kludge and you don't need PHP or any other server-side language to do it. Using AJAX - Call a remote HTML file with AJAX in the onLoad event handler of the body and place the returned page inside a blank DIV layer in the first HTML file. You might notice a slight lag as the sub-pages load up, depending on the speed of your server, but it works flawlessly and you can do it for as many files as you want to include. Edit - I guess you could also use iFrames, but nowadays, that's all kinds of "ick".
You cannot use include in html, but you can use iframe Example: <iframe width="" height="" src="www.yourlinkgoesher.com/blablab.html" scrolling='no' noresize="noresize">
I guess you are talking about the php include! if so, then here is how you can use it- "<?php include("url-of-the-file.php"); ?>"replace url-of-the-file with the exact url of your file that you wan't to include! for example, if you've created a file called nav-menu and it is on the public_html folder then the url would be only the name of the file i.e., in this case- nav-menu.php. while using this code do make sure that the included file should just contain the content, no any extra tags like , or anything else!
in php you can use include like this = "<?php include("url-of-the-file.php"); ?>" in html thee is no ny include named property. you can use the simple include in hml like this <body> <p>include</p> </body> yu can use include in any tag in html.
