title: how to add a header to all html pages (preferably without javascript)
body: <p>I was wondering how to add a header (or just any html file) into another html file. I tried using iframes, but it just redirected what was inside of the iframe. Once I finish my website, I will probably have a lot of pages, so it will be very useful to just be able to add a header that can be updated by only changing one file, instead of having to change it on all of the pages. Does anyone know how to do this? Thanks in advance.</p>
