如何使复选框四舍五入？

Question

有没有办法使用引导程序或一些 css 属性来制作带有圆角的复选框？

Answer 1

但是，仅使用 css，您会丢失复选框。

.checkbox-round {
    width: 1.3em;
    height: 1.3em;
    background-color: white;
    border-radius: 50%;
    vertical-align: middle;
    border: 1px solid #ddd;
    appearance: none;
    -webkit-appearance: none;
    outline: none;
    cursor: pointer;
}

.checkbox-round:checked {
    background-color: gray;
}

<input type="checkbox" class="checkbox-round" />

.container {
  display: block;
  position: relative;
  padding-left: 35px;
  margin-bottom: 12px;
  cursor: pointer;
  font-size: 22px;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
  
}

/* Hide the browser's default checkbox */
.container input {
  position: absolute;
  opacity: 0;
  cursor: pointer;
  height: 0;
  width: 0;
}

/* Create a custom checkbox */
.checkmark {
  position: absolute;
  top: 0;
  left: 0;
  height: 25px;
  width: 25px;
  background-color: #eee;
  
border-radius: 15px;
}

/* On mouse-over, add a grey background color */
.container:hover input ~ .checkmark {
  background-color: #ccc;
}

/* When the checkbox is checked, add a blue background */
.container input:checked ~ .checkmark {
  background-color: #2196F3;
}

/* Create the checkmark/indicator (hidden when not checked) */
.checkmark:after {
  content: "";
  position: absolute;
  display: none;
}

/* Show the checkmark when checked */
.container input:checked ~ .checkmark:after {
  display: block;
}

/* Style the checkmark/indicator */
.container .checkmark:after {
  left: 9px;
  top: 5px;
  width: 5px;
  height: 10px;
  border: solid white;
  border-width: 0 3px 3px 0;
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

<label class="container">One
  <input type="checkbox" checked="checked">
  <span class="checkmark"></span>
</label>
<label class="container">Two
  <input type="checkbox">
  <span class="checkmark"></span>
</label>
<label class="container">Three
  <input type="checkbox">
  <span class="checkmark"></span>
</label>
<label class="container">Four
  <input type="checkbox">
  <span class="checkmark"></span>
</label>

Answer 3

试着去做

body {
  background-color: #f1f2f3;
  -webkit-box-align: center;
      -ms-flex-align: center;
          align-items: center;
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
}

.container {
  margin: 0 auto;
}

.round {
  position: relative;
}

.round label {
  background-color: #fff;
  border: 1px solid #ccc;
  border-radius: 50%;
  cursor: pointer;
  height: 28px;
  left: 0;
  position: absolute;
  top: 0;
  width: 28px;
}

.round label:after {
  border: 2px solid #fff;
  border-top: none;
  border-right: none;
  content: "";
  height: 6px;
  left: 7px;
  opacity: 0;
  position: absolute;
  top: 8px;
  transform: rotate(-45deg);
  width: 12px;
}

.round input[type="checkbox"] {
  visibility: hidden;
}

.round input[type="checkbox"]:checked + label {
  background-color: #66bb6a;
  border-color: #66bb6a;
}

.round input[type="checkbox"]:checked + label:after {
  opacity: 1;
}

<div class="container">
  <div class="round">
    <input type="checkbox" id="checkbox" />
    <label for="checkbox"></label>
  </div>
</div>

Answer 4

最好和最简单的方法之一是使用 CSS 剪辑路径属性：

input[type="checkbox"] {
  width: 45px;                         /* Set width */
  height: 45px;                        /* Set height */
  clip-path: circle(46% at 50% 50%);   /* Set the clip path of circle*/
}

如果您仍然看到一些尖角，请尝试减少第一个百分比值（我使用的是 46%），稍微尝试一下，它肯定会起作用。

Answer 5

我认为制作圆角的最佳方法是使用border-radius 属性。 This site 有一个很好的复选框集合。 例如：

cursor: pointer;
position: absolute;
width: 20px;
height: 20px;
top: 0;
border-radius: 10px;

最后一行(border-radius: 10px) 会给你一个圆角复选框。
