javascript - 更改按钮样式不起作用

Question

我正在使用完整日历。我想更改标题上按钮的默认状态、悬停状态或事件状态。

所有我想要的:

default: black background, white text color  
hover :  red background color,  white text color  
active:  green background color,  white text color

CSS代码:

.fc-state-default {
  color: white;
  background-color: black;
}

.fc-state-active {
  background-color: green;
}

.fc-state-hover {
  background-color: red;
  color: white;
  border-color: black;
  border-width: medium;
}

由于某些我无法理解的原因，我无法更改这些按钮的样式。

这是一个 js fiddle 。 JSFIDDLE

拜托，有人能帮帮我吗!

如果我有这样的东西，请编辑:

<div class="fc-right">
<div class="fc-button-group">
<button type="button" class="fc-month-button fc-button fc-state-default fc-corner-left fc-state-active">month</button>
<button type="button" class="fc-agendaWeek-button fc-button fc-state-default">week</button>
<button type="button" class="fc-agendaDay-button fc-button fc-state-default">day</button>
<button type="button" class="fc-today-button fc-button fc-state-default fc-corner-right fc-state-disabled" disabled="disabled">today</button>
</div>
</div>

这很简单，只需添加这些 css 类:

.fc-button .fc-button-inner:hover {
    background-color: red;
    color: #fff;
}

.fc-button.fc-state-active .fc-button-inner {
    background-color: green;
    color: #fff;
}

.fc-button .fc-button-inner {
    background-color: #000;
    color: #fff;
}
