Answer 1

Of course it's possible, take it and make it up
Is it really so difficult to just rip off styles from another site? If you have problems with this, it may be worth considering whether you even need to do this?

Answer 2

If you make up on bootstrap, then these are two blocks

<div class="container">
   <div="row">
      <div class="col-md-3">Sidebar</div>
      <div class="col-md-9">Content</div>
   </div>
</div>
