Answer 2

You can use the following:

div[data-weight="bold"] { font-weight: bold; }

But I don't believe there's any way to use an attribute as a property without some JavaScript

Answer 3

You cannot achieve what you ask about in pure CSS. Using jQuery it could be done this way:

$.each($('div'), function(i, div) {
    $.each($(this).data(), function(key, val) {
        var realKey = key.replace(/([A-Z]{1})/g, '-$1').toLowerCase();
        $(div).css(realKey, val);
    })
})​
