I`m just starting in the bussiness of making web sites and needed to have a web site ready from one day to another to impress one possible client... So this one was made in one night, with the help of fireworks and dreamweaver.(thanks macromedia!) Now that I have more time, i`d apreciate some suggestions about it`s design. here it is:
One thing I noticed is a little space under the homepage_r1_c1.jpg image (the one that says Alpha Web Sites) that creates a black line between that image and the one below it. Also, under the homepage_r1_c1.jpg (Portfolio) and homepage_r1_c1.jpg (Contato) images. That's only on the homepage, though.
About the line you mentioned, I think it only shows on netscape because i`m using ie5.5 and i can`t see it. Are you using netscape? I just got my new computer and had no time to download netscape yet...
