Checboxex右对齐，但在下面显示另一个复选框

标签： html css

大家好。我有一个小问题，我希望课程偏好设置的复选框位于中间，而不是与底部的其他文本框在同一位置。我希望它成为页面的中心。就像在学术中字母D之后的某个地方。无论我尝试什么，checboxs都将限制在右侧。我试图将其浮动，但它不起作用。

有几种方法可以使用CSS将元素居中，一种用于将一组元素居中的方法是将所有这些元素封装在div等容器标签中并放置该容器标签。

因此，将所有复选框标签括在 div 标签内，并带有一个类（例如），说“ 外部容器”，并为其提供以下CSS： 

.outer-container {
  display: inline-block;
  position: relative;
  left: 50%;
  transform: translateX(-50%);
}

并从您的.container css中删除margin-left

我在下面的代码段中做了这些更改，请尝试使用此方法。

body {
  background: url(ewp.jpg);
  background-size: cover;
}

.firstform {
  border-radius: 5px;
  background: green;
  padding: 20px;
  width: 550px;
  margin: auto;
  color: #fff;
  font-size: 16px;
  font-family: verdana;
  margin-top: 100px;
  opacity: 0.8;
}

.firstform h1 {
  text-align: center;
  margin: 0;
  padding: 0;
}

.firstform input,
select {
  width: 50%;
  padding: 12px 20px;
  display: inline-block;
  border: 1px solid #ccc;
  border-radius: 4px;
  box-sizing: border-box;
  font-size: 18px;
  background: black;
  color: white;
  opacity: 0.9;
  /* removed margin-left */
}

.outer-container {
  display: inline-block;
  position: relative;
  left: 50%;
  transform: translateX(-50%);
}

.container {
  display: block;
  position: relative;
  padding-left: 25px;
  margin-bottom: 12px;
  /* margin-left: 24em; */
  cursor: pointer;
  font-size: 12px;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

}


/* On mouse-over, add a grey background color */

.container:hover input~.checkmark {
  background-color: #ccc;
}


/* When the radio button is checked, add a blue background */

.container input:checked~.checkmark {
