Ok here's a rough illustration that hopefully explains what I'm looking to do. Can you have separate .html(?) files that load in separate places on your page? So say you have the header, which contains a logo, some links, info, etc. and you want that to load on every page on your site, so you just make it its own thing that loads separately. Then you've got the unique content per page, which will obviously differ per page, so that becomes like a regular page. Then on the side you've got panels for navigation, or ads, or bio info, or whatever, and you want those to be *updateable* across all pages at once. So you want them to be their own objects that load on each page, so when it comes time to update it, you just update one file and then the changes are loaded globally on all your pages, rather than having it have to be changed manually on each page, which could get tedious if you have 100s of pages on your site. Kind of like how if you change the source of an image, it changes across your website everywhere it is loaded; I want html on parts of my page to be able to be changed globally like that. So is this possible, and how?
