Question

选中复选框后，我们要应用一个超出复选框区域的刻度。应用背景图像不起作用，因为它不能超出复选框区域。

所以，我想到了创建嵌套跨度并将背景图像应用到外跨度。但是，刻度图像会被内部跨度隐藏。

快速jsfiddle（不显示图片）是here

<span class="outer"> <span class="inner"> </span> </span> span.inner{ display:inline-block; width:10px; height:10px; border:1px solid; background-color:yellow; } span.outer{ display:inline-block; width:20px; height:20px; border:1px solid red; box-sizing:border-box; padding-left:3px; padding-top:1px; background-color:orange; background-image:url('sometickimage.png'); }

基本上，勾号会被黄色背景的跨度隐藏。

有没有办法在没有绝对定位的情况下实现这一目标？

Answer 1

尝试这样的事情：

<input type="checkbox" id="checkbox69" class="css-checkbox lrg" checked="checked">
<label for="checkbox69" name="checkbox69_lbl" class="css-label lrg out"> A tick which is going out of the checkbox </label>

与CSS相关联：

label {
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}

input[type=checkbox].css-checkbox {
  position: absolute; 
overflow: hidden; 
clip: rect(0 0 0 0); 
height:1px; 
width:1px; 
margin:-1px; 
padding:0;
border:0;
}

input[type=checkbox].css-checkbox + label.css-label {
padding-left:20px;
height:15px; 
display:inline-block;
line-height:15px;
background-repeat:no-repeat;
background-position: 0 0;
font-size:15px;
vertical-align:middle;
cursor:pointer;
}

input[type=checkbox].css-checkbox:checked + label.css-label {
background-position: 0 -15px;
}

.css-label{
background-image:url(http://csscheckbox.com/checkboxes/dark-check-      green.png);
}

.vlad{background-image:url(http://csscheckbox.com/checkboxes/vlad.png);}



input[type=checkbox].css-checkbox.sme:checked + label.css-label.sme{

 background-position: 0 -16px;
}
input[type=checkbox].css-checkbox.lrg + label.css-label.lrg {
padding-left:22px;
height:20px; 
display:inline-block;
line-height:20px;
background-repeat:no-repeat;
background-position: 0 0;
font-size:15px;
vertical-align:middle;
cursor:pointer;
}

input[type=checkbox].css-checkbox.lrg:checked + label.css-label.lrg{

background-position: 0 -20px;
}

以下是使用CSS伪类的示例。根据您的需要调整！

* {
  font-family: arial;
}
input[type=checkbox] {
  display: none;
}
label {
  display: inline-block;
  color: #666666;
  cursor: pointer;
  position: relative;
  padding-left: 35px;
  margin: 7px 10px;
  font-size: 16px;
  line-height: 20px;
}
label:before {
  line-height: 20px;
  content: "";
  display: inline-block;
  width: 20px;
  height: 20px;
  margin-right: 10px;
  position: absolute;
  left: 0;
  top: -1px;
  border-radius: 3px;
  background-color: #f5f5f5;
  border: 1px solid #aaaaaa;
  box-shadow: 1px 1px 1px rgba(0, 0, 0, .2);
}
input[type=checkbox]:checked + label:before,
label:hover:before {
  content: "\2713";
  text-shadow: 1px 1px 1px rgba(0, 0, 0, .2);
  font-size: 30px;
  color: #aaaaaa;
  text-align: center;
  line-height: 12px;
  width: 18px;
  padding-left: 2px;
}
label:hover:before {
  color: #d5d5d5;
  text-shadow: none;
}

<div class="checkbox">
  <input id="check1" type="checkbox" name="check" value="Morning">
  <label for="check1">Morning</label>
  <br>
  <input id="check2" type="checkbox" name="check" value="Evening">
  <label for="check2">Evening</label>
</div>
