Answer 1

Using the css float will work if you are willing to assign a fixed width to your div's.

<style>
  div.parent1 {
    width: 800px;
  }

  .child1 {
    float: left;
    width: 400px;
  }

  .child2 {
    float: right
    width: 400px;
  }

  .child3-container {
    clear:both;
    text-align: right;
  } 

</style>

<div class=parent1>
  <div class=child1>some text</div> 
  <div class=child2>some text</div> 
  <div class='child3-container' >
    <div class=child3>some text</div> 
  </div>
</div>
