javascript - Including third party header and footer -

i have little web app. clients utilize on site. create seamless (a part of own site), set app within iframe on website. way don't have worry header , footer (branding/styling etc). reason, specs have changed , app not within iframe. leads problem have maintain consistent header , footer branding/styling each client. have many clients , not possible me maintain each 1 of them , maintain updated time.

so, trying come solutions allow me inherit header , footer client , utilize on site. thinking telling client maintain header , footer html file (and maintain per branding). create ajax phone call , phone call html content on page. way never have worry header , footer.

what other ways can suggest can solve problem? experiences such situations? how did deal it?

i know not specific programming question thought best place answer. thanks

instead of placing web app within iframe can place header , footer within frame in web app.
