Question

我有一个来自Bootstrap的按钮组：

<div class="btn-group btn-group-toggle" data-toggle="buttons">
            <label class="btn btn-secondary active">
              <input type="radio" name="options" id="option1" autocomplete="off" checked> Active
            </label>
            <label class="btn btn-secondary">
              <input type="radio" name="options" id="option2" autocomplete="off"> Radio
            </label>
            <label class="btn btn-secondary">
              <input type="radio" name="options" id="option3" autocomplete="off"> Radio
            </label>
      </div>

也许是基本的，但我正在尝试更改：

选中/未选中的背景颜色
文本-字体/颜色

，没有任何效果。像这个： Bootstrap 4: Buttongroup - change active color

Answer 1

您需要

/* selected btn css */
.btn-group-toggle .btn:not(:disabled):not(.disabled).active, .btn-group-toggle .btn:not(:disabled):not(.disabled):active, .show>.btn.dropdown-toggle {
      color: #fff;
      background-color: #2196F3;
      border-color: #2196F3;
}

/* non selected btn css */
.btn-group-toggle .btn {
  color: #fff;
  background-color: #b7b7b7;
  border-color: #6c757d;
}

所以看起来像这样

Answer 2

只需将以下属性放入.active类。

.active{
   background-color: #8064A2 !important;
}

您完成了。

.active{
   background-color: #8064A2 !important;
}

Answer 3

如果我理解您的问题，那么您希望获得与链接的其他SO帖子相同的效果。

尝试添加此CSS：

.btn .btn-secondary, .active {
  background-color: #e21833 !important;
  border-color: #e21833 !important;
  color: yellow !important;
}

.btn .btn-secondary, .active:hover {
  background-color: #900900 !important;
  border-color: #900900 !important;
  color: white !important;
}

您可以将!Important属性用于CSS。

.btn.active {
    background-color: lime !important;
    border-color: lime !important;
    color: yellow !important;
}
