Good Web Design Software?

Hey my friend and I “designs” websites. But we often have a third wheel to code websites. Together we made one site (pacerobotics.com) but we feel like we should be doing our own coding, and I’m not really sure what to use. Dreamweaver seems to have a n00b stigma attached to it. I’m willing to learn coding, but if we code what software do you recommend? (On a mac). Also I’m very into the fancy (not tacky) effects. (lightbox etc.)
