Hi,

I have a rounded box, everything is ok within it but when I put in it floated div or paragraphs , one to left and one to right are showed outside the box...

this is my css code:

/* set millions of background images */
.rbroundbox { background: url(images/nt.gif) repeat; }
.rbtop div { background: url(images/tl.gif) no-repeat top left; }
.rbtop { background: url(images/tr.gif) no-repeat top right; }
.rbbot div { background: url(images/bl.gif) no-repeat bottom left; }
.rbbot { background: url(images/br.gif) no-repeat bottom right; }

/* height and width stuff, width not really nessisary. */
.rbtop div, .rbtop, .rbbot div, .rbbot {
width: 100%;
height: 7px;
font-size: 1px;
}
.rbcontent { margin: 0 7px; }
.rbroundbox { width: 99%; margin: 1em auto; }
.leftinbox{
float:left;
color:#FFFFFF;
width:49%;
}

.rightinbox{
float:right;
width:49%;
color:#FFFFFF;
}

and this my html:

<div class="rbroundbox">
    <div class="rbtop"><div></div></div>
        <div class="rbcontent">
        <div class="leftinbox">

</div><!-- /rbroundbox -->

Link of your page will help more then code. But just for start you have eight open divs and only six closed???

My wild guess from your code is that you need to give the container box some paddings.

About the div's, all of them are closed nicely. Did calculations and even checked with syntax highlighter no problem with them
