Logo Size + Promotional Headline Text

Hi Sakin, I've read a lot of your advice & I have to say thanks as it's been a massive help for a newcomer like myself. However, I'm stumped on two things: 1) Changing Logo size. I'd really love for it to be much bigger than it currently is, however it simply won't. I resized the resized the logo that I saved numerous times however it always came out the same small size. I also tried the CSS 'codes' you gave out but ..... Any idea? 2) Font Colour of Promotional Headline Text. For some reason it's white and invisable. I honestly have no idea how it got that way, but nothing I've tried has worked. Again I attempted the CCS 'codes' that you gave out, but to no success .... tho it must be said that this whole CSS thing is new to me. Thahnks in advance for any help, Steve
