How do I align a label and a textarea?

My code ends up like:

             XXXXX
             XXXXX
Description: XXXXX

I want:

             XXXXX
Description: XXXXX
             XXXXX

"Description" sometimes spans multiple lines.

Code:

<p class="DataForm">
    <label>Blah blah blah Description:</label>
    <asp:TextBox ID="txtBlahblahblahDescription"
                 runat="server"
                 TextMode="MultiLine"
                 Rows="8"
                 Columns="50"></asp:TextBox><br/>
</p>

CSS:

.DataForm {
}
.DataForm label {
    display: inline-block;
    font-size: small;
    margin-left: 5px;
    width: 5%;
    min-width: 60px;
}
.DataForm input {
    margin-right: 9px;
    display: inline-block;
    width: 21%;
    min-width: 30px;
}
