实现鼠标悬停容器时触发Button的CSS Hover效果

想要实现鼠标悬停**整个容器（而非仅按钮本身）**时，触发按钮的样式变化。目前只有悬停按钮本身时样式才会改变。尝试将CSS中.button:hover span替换为h8:hover span后，仅部分生效，剩余相关样式无法触发。

需要将所有与按钮hover相关的样式选择器，修改为容器hover时作用于内部按钮的形式。具体来说，把所有.button:hover的选择器替换为h8:hover .button，这样当鼠标悬停在h8容器上时，按钮的全套hover样式都会被触发。

修改后的关键CSS代码片段 #

/* Span on container hover and button active */
h8:hover .button span,
.button:active span {
    opacity: 0;
    -moz-transform: scale(0.3);
    -ms-transform: scale(0.3);
    -o-transform: scale(0.3);
    transform: scale(0.3);
}

/* Show :before pseudo-element on container hover, :after on button active */
h8:hover .button:before,
.button:active:after {
    opacity: 1;
    -webkit-transform: translate(0, 0);
    -moz-transform: translate(0, 0);
    -ms-transform: translate(0, 0);
    -o-transform: translate(0, 0);
    transform: translate(0, 0);
    -webkit-transition-delay: .4s;
    -moz-transition-delay: .4s;
    -o-transition-delay: .4s;
    transition-delay: .4s;
}

说明 #

修改后，当鼠标悬停在h8容器的任意区域时，内部按钮会触发完整的hover动画：原文字缩放消失，同时显示data-hover属性定义的内容；按钮的active状态保持原有逻辑不变。
