专门用于 :hover 的元素覆盖 :active 的等效类 [英] elements specifically for :hover overriding the an equivalent class for :active

问题描述

我的代码有一个背景，其字体颜色分配给一个类，然后有单独的类用于更改 :hover 或 :active 上的颜色，但除非我删除 :hover 特定类，否则不会触发 :active 状态.CODEPEN

I have code to have a background with a font color assigned with one class then have separate classes for changing the color on :hover or :active but the :active state does not trigger unless I remove the :hover specific class. CODEPEN

HTML:

<div class="backgroundRed backgroundGreenHover backgroundBlueActive" style="width: 100px; height: 100px;"></div>

CSS:

.backgroundRed, .backgroundRedHover:hover, .backgroundRedActive:active{background:red;}
    .backgroundGreen, .backgroundGreenHover:hover, .backgroundGreenActive:active{background:green;}
    .backgroundBlue, .backgroundBlueHover:hover, .backgroundBlueActive:active{background:blue;}

推荐答案

:active 伪类应该在 :hover 之后，否则 :hover 覆盖(链接相关的伪类的顺序是::link | :visited | :hover | :active.).您的代码示例按预期工作，但如果您更改类 :active 伪类永远不会应用.

:active pseudo-class should go after :hover, otherwise the :hover overwrites (The order for the link-relates pseudo-clasess is: :link | :visited | :hover | :active.). You code example works as expected but if you change the classes the :active pseudo-class never applies.

.backgroundRed,
.backgroundRedHover:hover,
.backgroundRedActive:active {
  background: red;
}

.backgroundGreen,
.backgroundGreenHover:hover,
.backgroundGreenActive:active {
  background: green;
}

.backgroundBlue,
.backgroundBlueHover:hover,
.backgroundBlueActive:active {
  background: blue;
}

<div class="backgroundRed backgroundBlueHover backgroundGreenActive" style="width: 100px; height: 100px;"></div>

您需要更多的 CSS 行，但在 :hover 之后使用 :active 重新排序类可以正常工作.

You need more CSS lines but reordering the classes with :active after the :hover works fine.

.backgroundRed,
.backgroundRedHover:hover {
  background: red;
}

.backgroundGreen,
.backgroundGreenHover:hover {
  background: green;
}

.backgroundBlue,
.backgroundBlueHover:hover {
  background: blue;
}

.backgroundRedActive:active {
  background: red;
}

.backgroundGreenActive:active {
  background: green;
}

.backgroundBlueActive:active {
  background: blue;
}

<div class="backgroundRed backgroundBlueHover backgroundGreenActive" style="width: 100px; height: 100px;"></div>
