thanks.
yes, well, thats the most best resource on web of course. but i am sorted anyway, all it was a silly mistake, i was amend-saving the style.css in another folder whereas it is linked from the header file which assumes it is in the includes folder, so i copied it thr, and it started listening to me. but more importantly is as i am using netbeans ID, its very helpful to explain all the selectors---classes---even values, now, changing the same style.css, i have an entirely new style sheet. don't think i will need any tutorials anymore. just adding a bit of flash and its all sorted.
