1) Take a course from a professor who actually knows something about web development. Someone who tells you to use Dreamweaver doesn't. (If it's university policy, find a better university.) 2) We'd have to see the actual site, not pictures of it, to comment on the HTML.
Also the massive background images are NOT real world deployable, text over background images of such high contrast often leads to making the text painful to read (which is why you do NOT see real websites doing that)... ... and yeah, +1 on find another professor and/or university, though good luck with that given that most educators cannot keep up with the pace of technology or have corporate kickbacks to the school result in garbage like DW being shoved down their throats. ... and yeah. We'd have to actually see the site, not some goofy pictures of a site to really weigh in on it in a meaningful manner, and if you are using the WYSIWYG side of Dreamweaver, it's templating system, or any of the Wizards/code generation tools, it's automatically inaccessible rubbish where everything you are being taught is going to have to be unlearned if you ever want to do this for real. ...and is that monster maze for the Zed-X 81?
Wait wait wait... UNIVERSITY GRADE education and that's what they're teaching you. My advice - If you want to truly learn HTML or web design, ditch that teacher, start with a fresh slate and a blank text document in Notepad++/Sublime Text. Give us that HTML code and I assure you, the people here will shoot it to pieces (Ergo Deathshadow). From simply looking at it, it looks like you've used tables, massive background images, poor formatting, poor design to deliver little actual content. Start again with a fresh slate. ~Jam
