I should have looked for the news page again :(
How about having a dummy point on the template for allowing a user-side chosen Javascript to be placed there automatically, which would change the CSS on the client's side only? The Javascript could be something like as follows, which is something I have as a compressed form as a bookmark:
function() { var newSS, styles = '* { background: #E9E9E9 ! important; color: #000000 !important } :link, :link * { color: #3333EE !important } :visited, :visited * { color: #551A8B !important }'; if (document.createStyleSheet) { document.createStyleSheet("javascript:'" + styles + "'"); } else { newSS = document.createElement('link'); newSS.rel = 'stylesheet'; newSS.href = 'data:text/css,' + escape(styles); document.getElementsByTagName("head")[0].appendChild(newSS); } })();
But I guess the template doesn't allow for this kind of hacking :(
Anyway, if and when I get annoyed with the colouring, I'll share a bookmark here for quickly changing only the text colours, since it's hard to please everyone ;)
