妳可以定義寬高,和圖片url。或者直接用
<asp:Button?ID="btnLogin"?runat="server"?Text="?登錄?" CssClass="btn_5"?/>?寫在樣式裏邊.btn_b1{width:155px;height:90px;line-height:60px;border:0px;font-size:14px;text-align:center;color:#fff;background:url(../images/btn_b1.png)?no-repeat;cursor:pointer;display:inline-block;text-decoration:none;font-weight:bold;}
.btn_b1:hover{color:#fff;?text-decoration:none;}
