Question

我在学校项目中添加了一些CSS，并且悬停效果不适用于asp：button。我这样链接CSS类：

<link type="text/css" rel="stylesheet" href="StyleSheet1.css"/>

然后在.aspx站点中单击：

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="txt" CssClass="glow-on-hover"/>

按钮具有样式，但是单击或将鼠标移到按钮上时均无效。但是，当我在html按钮上使用它时，它确实可以工作。我该如何在asp：button上工作？

.glow-on-hover {
    width: 220px;
    height: 50px;
    border: none;
    outline: none;
    color: #fff;
    background: #111;
    cursor: pointer;
    position: relative;
    z-index: 0;
    border-radius: 10px;
}

    .glow-on-hover:before {
        content: '';
        background: linear-gradient(45deg, #ff0000, #ff7300, #fffb00, #48ff00, #00ffd5, #002bff, #7a00ff, #ff00c8, #ff0000);
        position: absolute;
        top: -2px;
        left: -2px;
        background-size: 400%;
        z-index: -1;
        filter: blur(5px);
        width: calc(100% + 4px);
        height: calc(100% + 4px);
        animation: glowing 20s linear infinite;
        opacity: 0;
        transition: opacity .3s ease-in-out;
        border-radius: 10px;
    }

    .glow-on-hover:active {
        color: #000
    }

        .glow-on-hover:active:after {
            background: transparent;
        }

    .glow-on-hover:hover:before {
        opacity: 1;
    }

    .glow-on-hover:after {
        z-index: -1;
        content: '';
        position: absolute;
        width: 100%;
        height: 100%;
        background: #111;
        left: 0;
        top: 0;
        border-radius: 10px;
    }

@keyframes glowing {
    0% {
        background-position: 0 0;
    }

    50% {
        background-position: 400% 0;
    }

    100% {
        background-position: 0 0;
    }
}

<button class="glow-on-hover" type="button">txt</button>

伪选择器:before和:after不能在<input type="submit" />上使用，因为<input>不能包含任何子代。

您能否更改代码以呈现<button>而不是<input>。

CSS悬停不会在ASP按钮上生效
