3 Column Site

Hi guys,

I decided to make my site to have 3 columns. I want a sidebar on each side and my content in the middle on my index.php. Right now my 2 sidebars appear below my content at the bottom of the page.

Here’s my css code. What needs to be changed to have them all at the top?

#content
{
  width: 30%;
  margin-left: 30%;
}#sidebar
{
  background-color: #FCF1E2;
  color: #4A2C00;
  border: 1px solid #FDE5C3;
  width: 18%;
  margin-right: 50%;
  float: left;
}#sidebar2
{
  background-color: #FCF1E2;
  color: #4A2C00;
  border: 1px solid #FDE5C3;
  width: 18%;
  margin-left: 75%;

}
