Question

I know i can use imagebutton for image buttons. But i want to use css sprites to decrease downloaded image count. So i want to assign normal buttons to image via css class. But it seems like not working.

Here is the code and image i try

the button codes

    <asp:Button ID="btn1" CssClass="filter-tr" runat="server" />
<br />
<br />
<br />
<asp:Button ID="Button2" CssClass="filter-en" runat="server" />
<br />
<br />
<br />
<asp:Button ID="Button3" CssClass="flying" runat="server" />
<br />
<br />
<br />
<asp:Button ID="Button1" CssClass="fire" runat="server" />

here the css class code

    .filter-tr, .filter-en, .flying, .fire
{ display: block; background: url('images/image1.png') no-repeat; }

filter-tr { background-position: -0px -0px; width: 60px; height: 25px; }
filter-en { background-position: -0px -25px; width: 60px; height: 25px; }
flying { background-position: -0px -50px; width: 44px; height: 16px; }
fire { background-position: -0px -66px; width: 44px; height: 16px; }

but this way it works

.filter-tr {  display: block; background: url('images/image1.png') no-repeat;  background-position: -0px -0px; width: 60px; height: 25px; border-width:0px; }
