CSS无法正常使用ASP.Net Button

我在Visual Studio 2013中使用ASP.NET Web表单。

我正在使用以下CSS代码段作为按钮，

  .button::before {
      content: '';
      position: absolute;
      background: #071017;
      border: 50vh solid #1d4567;
      width: 30vh;
      height: 30vh;
      border-radius: 50%;
      display: block;
      top: 50%;
      left: 50%;
      z-index: 0;
      opacity: 1;
      -webkit-transform: translate(-50%, -50%) scale(0);
              transform: translate(-50%, -50%) scale(0);
    }

和

.button:active::before, .button:focus::before {
  -webkit-transition: opacity 0.28s ease 0.364s, -webkit-transform 1.12s ease;
  transition: opacity 0.28s ease 0.364s, -webkit-transform 1.12s ease;
  transition: transform 1.12s ease, opacity 0.28s ease 0.364s;
  transition: transform 1.12s ease, opacity 0.28s ease 0.364s, -webkit-transform 1.12s ease;
  -webkit-transform: translate(-50%, -50%) scale(1);
          transform: translate(-50%, -50%) scale(1);
  opacity: 0;
}

它适用于html按钮，但不适用于ASP.NET按钮。

<div class="button-container">
            <asp:Button ID="submit" class="button" runat="server" Text="Submit" OnClick="submit_Click" />
            <button type="submit" class="button"><span>Submit</span></button>
        </div>

这是我的ASP.NET网络表单

我没有太多使用CSS和ASP.NET的经验。我期待着你的帮助。

如果你想在asp.net控件中使用css类，请使用CssClass而不是下面的类。

<asp:Button ID="submit" CssClass="button" runat="server" Text="Submit" OnClick="submit_Click" />

在客户端渲染后找出控件的id。然后在该id上实现CSS。如果你使用id而不是css类。

对于asp.button，您应该使用CssClass代替class：

<asp:Button ID="submit" CssClass="button" runat="server" Text="Submit" OnClick="submit_Click" />
