How to set border to div element for text formatting?

Hi, I'm working a comment section page where it allows the user to leave a comment. I need assistance in my layout for displaying the comments into the repeater control. I used to put the comments inside the div element of the item and alternatingitem template of the repeater. And as a result, the comment would go straight along the line in the div element if the user is typing too many words or paragraph. What I want is to put a limit where the text will stop and proceed to the next line of the div element. How would I do that?What is the best way?Any suggestion? Here's my layoutfor the repeater control where I used to insert the comments.

Code:

---

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
       
        <HeaderTemplate>
  </HeaderTemplate>
 
  <ItemTemplate>
 
  <tr>
  <td >
  <div style="background-color:#FFFF66" >
    <%# Eval("Name") %> Says...
    <%# Eval("Comments") %>
    </div>
    </td>
 </tr>
 
  </ItemTemplate>
 
 
 
  <AlternatingItemTemplate>
 
  <tr>
  <td >
  <div style="background-color:#CCFF33" >
      <%# Eval("Name")%> Says...
  <%# Eval("Comments")%>
  </div>
  </td>
 </tr>
 
  </AlternatingItemTemplate>
 
  <SeparatorTemplate >
  <br />
 
  </SeparatorTemplate>
 
  <FooterTemplate>
  </FooterTemplate>
       
        </asp:Repeater>
