```
a:link
{ 
    color: white; 
    background-color: black;
    text-decoration: none;
    border: 2px solid white; 
}

a:visited
{ 
    color: white; 
    background-color: black;
    text-decoration: none;
    border: 2px solid white; 
}

a:hover
{
    color: black; 
    background-color: white;
    text-decoration: none;
    border: 2px solid black; 
} 

```

Button :

```
<asp:LinkButton ID="A" runat="server" Text="A"
    OnClick="searchalpha" cssClass="a" />

```

It's not working -- do you have any solution for this?
