One Page Website - Markup Validation

Ben set me the task of validating my website to make sure there were no errors within the website it self meaning that everybody would have no problem with viewing it, for example making sure that colourblind people can read the text as well as people who suffer with dyslexia. I started off with 10 errors and now i have corrected them down to only 2.

I now need to correct these 2 errors as soon as possible.
