Wrapping a paragraph inside a div?

How do I make my paragraph wrap inside my div? It is currently overflowing outside of the div and I have no idea how to stop the paragraph from overflowing over the edge. I do not want a scroll bar with:

overflow: scroll;

and the other overflow options don't seem to help here either... I have the following code:

div {
 width: 1200px;
 margin: 0 auto;
}
.container {
 overflow: hidden;
}
.content {
 width: 1000px;
 float: left;
 margin-left: 0;
 text-align: left;
}
.rightpanel {
 width: 190px;
 float: right;
 margin-right: 0;
 }

<div class="container">
   <div class="content">
   <p>Some content flow开发者_如何学运维ing over more than one line</p>
   </div>
   <div class="rightpanel">
   <!-- content -->
   </div>
</div>

Edit:

<div class="container">
<div class="content">
<div class="leftcontent">           
</div>
<div class="newsfeed">
<div class="newsitem">
<p>Full age sex set feel her told. Tastes giving in passed direct me valley as supply. End great stood boy noisy often way taken short. Rent the size our more door.

<div class="rightpanel">
</div>

I see now! You are giving all divs a width of 1200px. If you take that away, everything will look fine. .newsfeed and .newsitem are taking on this attribute.

You could alternatively give .newsfeed and .newsitem a width:

.newsfeed , .newsitem { width: 300px; }
