Validating my web site

After putting those animations in my page, it came out with a lot of errors more than 9. Today I had the meeting for (NOVA) so I came in a little bit late I hardly had time to do a lot of work but at least I fixed some errors I had in my CSS, which now it went down to three errors, in the other hand I have about 5 errors in the main page which is the HTML5, I'm hoping tomorrow I'll fix most of it, and try to place the animation where I want it to be because right now its not well placed.
