需要css切换帮助

Question

我想主要使用 css 进行切换。开关的左侧会显示颜色，右侧会显示黑白。我所需要的只是一个简单的动画，它涵盖了单击开关时正在使用的选项。我在 codepen 上查找了示例，但一切都与 SASS 或其他不同类型的代码有关，我真的不知道如何编辑或实现到我自己的代码中。

Answer 2

你不能用javascript吗？还是必须是 CSS？

如果您使用 javascript，您可以使用 document.getElementById('x').style.[ccstag] 来更改元素 CSS 属性的状态

我用它来显示和隐藏菜单中的一个选项。

function Showelement(id,n1){

    document.getElementById(id).style.display = "inline";
    document.getElementById(n1).style.display = "";

}

你可以用同样的东西，但是有你的

被隐藏的元素。 "" 会将元素的 CSS 返回到它在 JS 更改之前在您的 CSS 或样式中设置的内容。

希望这会有所帮助:)
