Every widget like block

Hi, I’m making WordPress theme right now and I have a problem. The person wants it widget ready but theme has blocks in sidebar. Every part is standalone block (categories, search,…), with more than one background via CSS 🙁

In non-widget it’s simple, every

• looks like:

  <li><div class="li-top"></div>
  <h2>Headline</h2>
  content
  <div class="li-bottom"></div></li>
