I'm working on a new layout for my design portfolio and since I want to have a blog as well, I'm just making the whole thing in Tumblr. I want to use something like PHP or HTML includes for the header and footer so I don't have to edit 15 pages of headers and footers whenever I make a change, but the problem is Tumblr doesn't allow either PHP or HTML includes (I've tried both and the code just doesn't render). I thought of using iframes, but after some experimentation, those just aren't going to work the way I need them to.
So my question is- is there any way I can create my header and footer files, host them on a different site and then call up the file in my Tumblr layout? I've spent several hours over the last few days scouring the internet and have not been ble to come up with anything. Thanks in advance for any suggestions!
