Dropshadow style spacing and hyperlink

I have a drop shadow screenname and there are 2 problems with it.

1) I'm trying to get space after it and it doesn't take. It overlaps with what's below it.
2) When I make it a hyperlink, it breaks funny. The second line below is a hyperlink.


Here is the image without the hyperlink, it runs into the box below it.


Here is the code for the screenname:

.ScreenName, .ScreenName a:link, .ScreenName a:visited, .ScreenName a:link:hover
{
   text-shadow: 1px 2px 3px #323232; /* filter: shadow(Color=#333333, Direction=135, Strength=5); */
   text-transform: uppercase;
   font: 'Trebuchet MS' , Arial, helvetica, verdana, sans-serif;
   font-size: 16px;
   font-weight: bold;
   padding: 3px 6px 3px 6px;
   margin-left: 15px; /*   width: 200px; */
   color: #FFF;

}

.ScreenName, .DarkBlueBox, .LightBlueBox, .InstructionBox, .ScreenName a:link, .ScreenName a:visited, .ScreenName a:link:hover
{
   border-style: none;
   -webkit-box-shadow: -3px 3px 4px rgba(50, 50, 50, 0.90);
   -moz-box-shadow: -3px 3px 4px rgba(50, 50, 50, 0.90);
   box-shadow: -3px 3px 4px rgba(50, 50, 50, 0.90);
}

.ScreenName, .DarkBlueBox, .InstructionBox, .ScreenName a:link, .ScreenName a:visited, .ScreenName a:link:hover
{
    background-color: #629FCC; 
}

.ScreenName
{
      margin-bottom: 55px !important;
}

Select allOpen in new window

And in the code in front:

<asp:Label ID="lblScreenName" runat="server"></asp:Label>

Select allOpen in new window

In the codebehind I set the text and if there is a hyperlink, add the HTML coding and class.

            lblScreenName.Text = "Register"
            lblScreenName.CssClass = "ScreenName"

Select allOpen in new window

Thanks!
