center content of linkbutton - asp.net

Question

I have a linkbutton inside a div. I have set the height & width of the div to look like a square using css. I have also set height & width of linkButton via css. Also my LinkButto
display propery is set to block.(To get the hyperlink effect all over the control).
what I want now is to center the LinkButton text vertically and horizontally.
I tried all possible properties of div and linkbutton with no luck.
Only way I could do this was setting padding(top, left, right) but then it messes up the layout.
.divblock
{
background-color :#EEEEEE;
border:2px solid;
width : 90px;
height :80px;
}
.Linkbutton
{
text-decoration: none ;
color :black !important;
display:block;
width : 85px;
height :80px;
}
aspx:
<div id="myDiv" runat="server">
<asp:DataList ID="dl1" runat="server" RepeatDirection="Horizontal" ItemStyle-CssClass ="Items" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
**<div class ="divblock">**
<asp:LinkButton **CssClass="Linkbutton"** OnCommand="PresItems_Command" ID="TestLB1" runat="server" Text="Test" />
</div>
</ItemTemplate>
</asp:DataList>
</div>
