Inner div to scroll if outer div is too small?

Question

Tentatively answered Thanks dcneiner - new answers are appreciated.

Hi, I'm trying to make a sidebar which on a website which will have a "panel" in it containing contact info. The problem is that on smaller screens, the text overflows the background.

Here is the CSS, where #navigation is the outer div and the inner div is called .innerPanel HTML to follow:

 #navigation{
      position: absolute;
      left: 1.5625em;
      top: 1.5625em;
      bottom: 1.5625em;
      display: block;  
      width: 12.5em;
      background: navy;
      border-right: 1px solid navy; 
      text-align: center;
      background: #B6D2F0;
      padding: 5px;
      color: #4A4A49;
      overflow: hidden;
    }

    #navigation .innerPanel{
        min-height: 200px; /* supply current height here */
        height: auto;
        overflow: auto;
    }

    .titleHead{
     display: block;
     padding-top: 0.9em;
     overflow: auto;
    }


    /* inverted corners for the links */
    #navigation #links {     
      position: relative;
      padding-top: 30px;
    }

    #navigation #links div div div h3{
      border-top: 1px solid navy;
      border-bottom: 1px solid navy;
      color: navy;
      padding: 0px;
      margin: 0px;
      margin-top: 1px;
      line-height: 1.2em;
    }

    #navigation div div div div ul{
      list-style-type: none;
      margin: 0px;
      padding: 0px;
    }

    #navigation div div div div ul li{
      text-align: center;
    }

    #navigation div div div div ul li a{
      display: block;
      text-decoration: none;
      font-weight: bold;
      color: #B6D2F0;
      padding: 0px;
      padding-left: 0;
      line-height: 2.5em;
      background: navy;
      border-bottom: #D8F4F2 1px dashed;  
      }

    #navigation div div div div ul li a:hover{
      display: block;
      text-decoration: none;
      font-weight: bold;
      color: #D8F4F2; 
      background: #0000A2;
    }

    #navigation div div div div ul #last a{
      border-bottom: 0px;
    }

`

Here is the HTML fragment. The nested Divs were for rounded corners, which were 'nixed' by the client

      <div id="navigation"> 
    <div id="logo" class="box"> 
      <div> 
        <div> 
          <div style="text-align: center;"> 
          <img src="./images/pictures/cbk-logo-sm.gif" alt="CBK Logo" /> 
          </div> 
        </div> 
      </div> 
    </div> 
 <div id="links" class="box"> 
      <div> 
        <div> 
          <div>          <ul> 
              <li id="home"> 
                <a href="index.php" title="Home">Home</a> 
              </li><li> 
                <a href="applications.php" title="Apply as a staff member or camper">Applications</a> 
              </li><li id="last"> 
                <a href="about.php" title="About our directors, our grounds and our campers">About</a> 
              </li> 
            </ul><div class="innerPanel"><div class="innerMost"><h4 class="titleHead"> 
      Contact Information</h4> 
             <h5 style="margin: 0.8em 0 0 0; padding: 0;">City Office (September-June)</h5> 
             <p style="font-size: 0.75em; margin: 0; padding: 0;">

      <p style="font-size: 0.75em; margin: 0; padding: 0;"> 
      <em>Phone:</em> 845-439-3200<br /> 
      <em>Fax:</em> 845-439-3154<br /> 
      <em>Email:</em> [email protected]<br /> 
      <em>Address:</em> 641 Knickerbocker Road, Livingston Manor, NY 12758
            </p></div></div>      </div> 
        </div> 
      </div> 
    </div> 
  </div>

I need a cross-browser solution to make the innerPanel dynamically add a scrollbar to itself so that on smaller screens, the content is clipped but accessible via scroll...

Preferably, the solution should be pure CSS.

Any ideas?

EDIT: I apologize for the ambiguity. I have a sidebar, called #navigation. It contains a logo, the menu and the contact information. I want the contact info to scroll where needed.
Everything else seems to display normally on 800x600 screens and up.

EDIT: As it stands now (dcneiner's answer,) innerPanel is a fixed height. I would like it to grow when possible, and if there is enough room, eliminate the scrollbar. Please note that there is an HTML div not mentioned in the CSS, which is contained inside of innerPanel. (innerMost)

Answer 1

What about #navigation { overflow: auto; }? That should make scrollbars when necessary.

Answer 2

I am a little unclear what you are asking, but it seems to me you either want overflow:auto on the #navigation element, or depending on your content and why it has a fixed height:

#navigation .innerPanel {
    max-height: 200px; /* supply current height here */
    height: auto;
    overflow: auto;
}

DOES NOT WORK IN IE6
IE6 does not support max-height.
