theme got soft rejected

my theme got soft rejected.they gave me some reasons where to improve my template.
they are:

  1. LATEST JQUERY: Make sure you are using the latest version of jquery, and it is included in your download.

  2. STRICT MODE REQUIRED: All JavaScript should be written with “use
    strict” mode on. Please note that strict mode is scoped. For concise
    code it is recommened to placed

  3. CSS TABLE OF CONTENTS: Make sure the CSS file is well documented with proper table of contents. For more information, see: http://www.smashingmagazine.com/2008/05/02/improving-code-readability-with-css-styleguides/

  4. SCROLLING ANIMATIONS: The scrolling animations are currently
    overused. Animation is a tool that should be used sparingly to help
    enforce the concept of your design. Please consider where you are using
    animations and their purpose.

  5. SPACING AND ALIGNMENT: There are spacing and alignment issues in
    this item. Please make sure that all elements are aligned properly and
    spacing is consistent from section to section. Here are some articles
    with more information regarding negative space and proper spacing: http://webdesign.tutsplus.com/articles/using-white-space-or-negative-space-in-your-designs--webdesign-3401,\ http://webdesign.tutsplus.com/articles/adding-space-to-your-designs--webdesign-14836
