added possibility to integrate slide headers and footers

[lpirl]

This is a quick hack to allow easier integration of slide headers and slide footers.
Example provided.

Without this patch, users are limited to specify headers and footers via templates within <div class="content …. When the aforementioned div does not fill the whole height of the presentation, a footer specified within a template does not really look like a footer (but rather like static content floating around in the middle of the screen).

Sadly, I will abandon Showoff for my current purpose, so I probably won't put more effort into this PR, but feel very free to merge this – I'd be happy if it is of any help.

Thanks for this cool project!

@lpirl It's a good idea to include headers and footers, but I'm not sure if this is the way to add them in. I can see a couple of places where it would interfere with the current design and layout.

I'm going to wait for @binford2k to get back and we'll discuss it. Thanks for contributing.

True, I wasn't too happy with this implementation either but it was the best place I could find and I tried not to break existing functionality. To be honest, I think a "proper" template system (including template inheritance etc.) would be a very beneficial feature as well. Thanks for considering.

@lpirl We're not going to merge this. You can add a header and/or footer using the existing templates functionality. It is not great, but it works. We will be reworking this and will definitely keep it in mind

You can add a header and/or footer using the existing templates functionality.

Can you? As mentioned in the OP, I was confronted with the problem that the templates are placed within <div class="content … and when the latter does not have a full height (e.g., on title slides), the footer floats around in the middle of the slide, what is not acceptable.
If one places the HTML elements for the header/footer at the top of the template, the outline shows the header/footer text for every item, which is not acceptable either.

I am sure I was lacking CSS ninja skills :) If you could provide an example, I am sure folks who come across this issue would be happy.

@lpirl I am going to rework (and clean up) the templating a bit to add the header/footer functionality you want. I believe that's the layer it belongs in, rather than in another markdown file. I'll reuse some of your ideas and will attribute you as a co-author.

Right now, you can do that with the templating layer, but yes it does take a bit of css weirdness. You'd add a header div and a footer div in the template and position them fixed using a custom stylesheet.

Alright, fixed to place text at the edges of the screen (and not the slide), fair enough.
Thanks for planned work on this and attribution.
