Soft Rejected - University HTML Template

Hey guys,
This is my first HTML, I need some help here!
And this is the feedback:

Thank you for your submission.

  1. Unfortunately, your submission is too similar to existing item(s) in our marketplace. Your upload must be a unique concept not based on any existing marketplace item.

  2. In this case, the submitted template is more like a ‘framework’ than a full fledged design. Make sure that all components are designed to work with your template’s concept.

  3. Parts of your design are either difficult to read or have contrast issues. Please make sure all sections of your design have adequate contrast and all text is easily readable.

  4. There are spacing and alignment issues throughout this item. Please take a moment to make sure that all elements are aligned perfectly and everything is spaced consistently from section to section.

Any help would be grea! I dont know what to change!
