Hyperlink description must wrap onto the next line

I have a hyperlink with an associated css that displays with a blue background.  In the code below, I want the wording to move onto the next line.  How do I specify this.  Currenlty "log in" is on 1 line and "for admin" is on the next line, but the spacing is all weird on the 2nd line .menubutton
{color:#F0E68C;
background-color:#104E8B;
width:120px;
font-size:1.2em;
font-weight:bold;
text-align:center;
padding:5px;
margin:10px}


&lt;asp:HyperLink ID="LoginHyperLink" runat="server" CssClass="menubutton" NavigateUrl="~/Login.aspx"&gt;Log In for Admin</asp:HyperLink> <br /> .
