problem s border

ahoj, fakt se snazim uz sem nepsat kazdou kravinu ale na tohle fakt nemuzu prijit.

Zobrazuje se mi spatne border-left u layoutu, kdyz do toho layoutu vloim text nebo cokoiv jineho.
viz. http://rodinnarealitka.dumapes.cz

v IE v pohode ale v mozille mi ten border mizi je to ten v prostrednim layoutu vlevo

CSS:
/* layout */
#kontejner {
width : 950px;
text-align : left;
margin : auto;
background-color: #D8E8FF;
background-image:url('background/kontejner.jpg');
background-repeat:repeat-y
}
#obalovaci {clear: both;}
#hlavicka_logo {
width : auto;
height : 236px;
background-image:url('background/hlavicka.jpg');
padding:0px;
border-bottom:3px solid black;border-right:3px solid black;border-left:3px solid silver;border-top:3px solid silver
}
#hlavicka_obrazek {
width : auto;
height : 146px;
background-image:url('background/jested.jpg');
padding:0px;
border-bottom:3px solid black;border-right:3px solid black;border-left:3px solid silver;border-top:3px solid silver
}
#horni_box {
width : 950px;
}
#levy_box{width: 190px;float: left;background-color: #B0D1FF;padding: 0px;border-left:3px solid #304F7B}
#obsah_box{width: auto;margin: 0 190px 0 190px;background-color:#D8E8FF;border-left:2px solid #304F7;border-right:2px solid #304F7B}
#pravy_box{width: 190px;float: right;background-color: #B0D1FF;padding:0px;border-right:3px solid #304F7B}
#paticka {
clear:both;
height: 35px;
background-color:#304F7B;
padding:0px;
color:white
}
.odsazeni {padding-left: 5px;padding-right: 5px;padding-top: 5px;padding-bottom: 5px;}


HTML:
<div id="obsah_box">
<div class="odsazeni">
<p>fasd</p>
</div>
</div>

kdyz dam widht, tak to bohuzel nefunguje :(
