Question

我创建了一个带有自定义复选框的div，我想通过自定义图像更改复选框图像。我已经完成了但是我无法改变图像的大小。请帮助我。

任何帮助将不胜感激。

            <div class="left">

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

我使用的CSS。

.checkbox {
display: inline-block;
cursor: pointer;
font-size: 13px; line-height:18px;
}
input[type=checkbox] {
display:none;   
}
.checkbox:before {
content: "";
display: inline-block;
width: 25px;
height: 25px;
vertical-align: middle;
background-color: rgb(248,183,51);
color: #f3f3f3;
text-align: center;
}
input[type=checkbox]:checked + .checkbox:before {
content: url("images/Tick.png");
text-shadow: 1px 1px 1px rgba(0, 0, 0, .2);
font-size: 15px;
}

Answer 1

您可以在不使用图像的情况下执行此操作，只需使用简单的字符和CSS，因此您可以通过调整字体大小或更改颜色来更改自定义复选框。

请参阅以下示例：

＆＃13;

/* Base for label styling */
[type="checkbox"]:not(:checked),
[type="checkbox"]:checked {
  position: absolute;
  left: -9999px;
}
[type="checkbox"]:not(:checked) + label,
[type="checkbox"]:checked + label {
  position: relative;
  padding-left: 25px;
  cursor: pointer;
}

/* checkbox aspect */
[type="checkbox"]:not(:checked) + label:before,
[type="checkbox"]:checked + label:before {
  content: '';
  position: absolute;
  left:0; top: 2px;
  width: 17px; height: 17px;
  border: 1px solid #aaa;
  background: #f8f8f8;
  border-radius: 3px;
  box-shadow: inset 0 1px 3px rgba(0,0,0,.3)
}
/* checked mark aspect */
[type="checkbox"]:not(:checked) + label:after,
[type="checkbox"]:checked + label:after {
  content: '✔';
  position: absolute;
  top: 3px; left: 4px;
  font-size: 18px;
  line-height: 0.8;
  color: #09ad7e;
  transition: all .1s;
  transform-origin: center;
}
/* checked mark aspect changes */
[type="checkbox"]:not(:checked) + label:after {
  opacity: 0;
  transform: scale(0);
  transform-origin: center;
}
[type="checkbox"]:checked + label:after {
  opacity: 1;
  transform: scale(1);
  transform-origin: center;
}
/* disabled checkbox */
[type="checkbox"]:disabled:not(:checked) + label:before,
[type="checkbox"]:disabled:checked + label:before {
  box-shadow: none;
  border-color: #bbb;
  background-color: #ddd;
}
[type="checkbox"]:disabled:checked + label:after {
  color: #999;
}
[type="checkbox"]:disabled + label {
  color: #aaa;
}
/* accessibility */
[type="checkbox"]:checked:focus + label:before,
[type="checkbox"]:not(:checked):focus + label:before {
  border: 1px dotted blue;
}

/* hover style just for information */
label:hover:before {
  border: 1px solid #4778d9!important;
}






/* Useless styles, just for demo design */

body {
  font-family: "Open sans", "Segoe UI", "Segoe WP", Helvetica, Arial, sans-serif;
  color: #777;
}
h1, h2 {
  margin-bottom: 5px;
  font-weight: normal;
  text-align: center;
}
h2 {
  margin: 5px 0 2em;
  color: #aaa;
}
form {
  width: 80px;
  margin: 0 auto;
}
.txtcenter {
  margin-top: 4em;
  font-size: .9em;
  text-align: center;
  color: #aaa;
}
.copy {
 margin-top: 2em; 
}
.copy a {
 text-decoration: none;
 color: #4778d9;
}

＆＃13;

<form action="#">
  <p>
    <input type="checkbox" id="test1" />
    <label for="test1">Red</label>
  </p>
  <p>
    <input type="checkbox" id="test2" checked="checked" />
    <label for="test2">Yellow</label>
  </p>
  <p>
    <input type="checkbox" id="test3" checked="checked" disabled="disabled" />
    <label for="test3">Green</label>
  </p>
    <p>
      <input type="checkbox" id="test4" disabled="disabled" />
      <label for="test4">Brown</label>
  </p>
</form>

自定义复选框背景图片属性

请使用background-image检查以下实时示例以获取自定义复选框：

＆＃13;

.checkbox {
display: inline-block;
cursor: pointer;
font-size: 13px; line-height:18px;
}
input[type=checkbox] {
display:none;   
}
.checkbox:before {
content: "";
 display: inline-block;
 width: 25px;
 height: 25px;
 vertical-align: middle;
 background-color: rgb(248,183,51);
 color: #f3f3f3;
 text-align: center;
}
input[type=checkbox]:checked + .checkbox:before {
  background: url("https://cdn1.iconfinder.com/data/icons/windows8_icons_iconpharm/26/checked_checkbox.png") no-repeat center center;
 text-shadow: 1px 1px 1px rgba(0, 0, 0, .2);
 font-size: 15px;
 background-size: 10px 10px;
}

＆＃13;

<div class="left">
  <input id="Option" type="checkbox">
  <label class="checkbox" for="Option"> </label>
</div>

＆＃13;

请确保您的图片存在于正确的路径中。
另外请考虑通过设置背景属性的水平和垂直位置来重新定位背景图像。

Answer 2

我做的主要事情是将背景background-size设置为cover。

＆＃13;

.checkbox {
 display: inline-block;
 cursor: pointer;
 font-size: 13px; line-height:18px;
}

input[type=checkbox] {
 display:none;   
}

.checkbox:before {
 content: "";
 display: inline-block;
 width: 40px;
 height: 40px;
 vertical-align: middle;
 background-color: rgb(248,183,51);
 color: #f3f3f3;
 text-align: center;
}

input[type=checkbox]:checked + .checkbox:before {
 background: url("https://cdn1.iconfinder.com/data/icons/windows8_icons_iconpharm/26/checked_checkbox.png");
 text-shadow: 1px 1px 1px rgba(0, 0, 0, .2);
 font-size: 15px;
 background-size: contain;

}

＆＃13;

 <div class="left">
  <input id="Option" type="checkbox">
  <label class="checkbox" for="Option"> </label>
 </div>
