Creare header con 2 colonne: logo a sinistra e banner a destra

[allin81]

Ciao
ma lo sto usando, ecco il css

div#sotto_header{
    float:left;
     line-height:0;
    background:#FFFFFF;
    margin-left: 0px;
    margin-top: 0px;
    margin-right: 0px;
    margin-bottom: 0px;
    padding:8px;
    width:1033px;
    border-left: 1px #3e7da3 solid;
    border-right: 1px #3e7da3 solid;
    border-bottom: 3px #dddddd solid;
}

div#breadcrumbs{
    float:right;
    font-family: 'PT Sans Narrow', sans-serif;
    color:#779dd4;
    font-size: 15px;
    font-weight:bold;
}

e questi sono i div

    <div id="sotto_header">
    <?php
    if (function_exists('dynamic_sidebar') && dynamic_sidebar('Sotto Header')): else : ?>
    <?php endif; ?>

        <div id="breadcrumbs">
        <?php
        if ( function_exists( 'breadcrumb_trail' ) ) breadcrumb_trail(); 
        ?>
        </div>
    </div>

allego lo screenshot che mi esce... i 2 elementi non sono allineati
