[unfixable] Using @media commands to print separate stylesheets?

[matgb]

OK, this one is beyond me. I can't figure out how the styles system creates different stylesheets, let alone how to tell it to do multiple different ones.

Specifically, I want to have a different sheet for screen media as well as one for all users (ie colourscheme goes for everyone, but put this box next to that one should be for computer displays, not mobile devices and similar).

Wordpress does this for the complete stylesheet:
link rel="stylesheet" href="http://s1.wp.com/wp-content/themes/pub/p2/style.css?m=1289584311g" type="text/css" media="screen"

But I want to do it in different sheets, this is partially for bandwidth purposes (my mobile contract has a large, but limited, DL limit) but also because some mobile devices and browsers get really confused by all-in-one stylesheets, Opera Mobile tries to ignore stuff it knows won't display properly (but can't always manage it, Blogspot blogs are worst for this), but a Palm Pre, I'm told, will try and put everything in the right place and shrink it, making DW unusable with styles on for a such a device.

So, two questions, one, how does the Styles system know which bit of the layer should create a separate sheet. Two, how do I figure out what the URL would be for each separate sheet in order to embed them for display properly?

Add "back to top" link to Transmogrified with s2 custom theme layer?

Many Dreamwidth s2/Core2 styles have the "back to top" link at the bottom of the Recent Entries view, but Transmogrified doesn't. I had the same problem on LJ, when I used the Bloggish layout with a custom style sheet and theme layer, but I couldn't solve it, not even by modifying s2 Mixit's code to fix the problem, because Bloggish lacked a "back to top" link in the HTML to hook the s2 to.

So my question is kind of two-fold:

Is there any way to get all the proper HTML (including the necessary but missing HTML links and the requisite s2 to make it all work) into Transmogrified, and if so, how?

Because my other problem is I cannot figure out how DW's s2 differs from LJ's version of it. So I would need someone to work out the code for me but hopefully someone who could also explain how s2 differs on DW from LJ's version (or at least point me in the right direction, if there's something I can read on that to make it more clear).

Because the way I figure it, if I can't read (that is, understand) the s2 on DW, I'll never be able to modify or write it. And I want to be able to do both.
