HTML, CSS and even FrontPage is killing me!!!

Started building my website on FrontPage
initially i thought everything was fine
why? cuz i don't haf to do e hard coding myself
so i continue building my site on FrontPage
till i realise the need to switch over to css
for? i also haf no idea why e sudden urge to do that
maybe because i wan my web to be proper html

so was reading around on css and how to do it
finally got it and seperate css from the html
which means i didn't place my css style in my html <"head>
instead i placed it in another file with a .css extension

then here comes the big big problem
there are sooooo much to change
like removing #$@#%^#@$
to #$@#%^#@$
I used not 1 nor 2 but at least 11 styles
and quite a handful or repeat
now i'm manually editing it in the code page
coverting everything to css style!!! hardwork
and now again, realise that some of my web pages
which haf e same content
but some different code!!!!!
gonna spend time finalising everything to one protocol-type!!!!!!!!

time to work hard -_-
