So is there a way to update all of your webpages at the same time. i mean, one time i found a small mistake on all of my webpages. and then i had to go through all 20 of my web pages to fix it. and damn, its a pain lol

I believe if you create your site using PHP, you'd be able to do just that.

yeah i use php. but how do you do that?

You can read this . You use php includes:

Or server-side includes, if you're just using straight HTML. Wikipedia, of course, has more info.

Server-side includes are a lot easier to use than PHP, but not as flexible.

so uh what am i suppose to do? is there a code for this?

and thanks for the links

Its not a code, its php includes. You learn how to include certain files.
The tutorial I gave you is for you to place your layout into a css file, header file, and footer file. Then you include (by following the tutorial) the css file, header file, and footer file on each page.

Then when you change your layout you only have to edit the css, header, and footer files.

thanks for breaking it down. i got it!
