CSS problem

Hi All,

I'm trying to place a 'Search form' in the right side of the header.

Within <div id="header">, <div id="logo-title"> with logo image is floated left. <div id="header-blocks"> with 'Search form' is floated right:

However as you can see from the link below, it is not floated far enough.

I spent quite some time trying to fix it, but had no success.

Can anybody give me a hint?

P.S. The CSS I use for "logo-title" and "header-blocks":

#logo-title /* Wrapper for logo, website name, and slogan /
{
border: 1px #634 solid;
float: left; / SVK */
}

#header-blocks /* Wrapper for any blocks placed in the header region /
{
border: 1px #234 solid;
clear: none; / SVK /
float: right; / SVK */
}
