css3 的样式复选框未以正确的方式显示标签

Question

我有以下 CSS 代码：

body {
    background: #555;
}



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


/* SQUARED THREE */
.squaredThree {
    width: 20px;    
    margin: 20px auto;
    position: relative;
}

.squaredThree label {
    cursor: pointer;
    position: absolute;
    width: 20px;
    height: 20px;
    top: 0;
    border-radius: 4px;

    -webkit-box-shadow: inset 0px 1px 1px rgba(0,0,0,0.5), 0px 1px 0px rgba(255,255,255,.4);
    -moz-box-shadow: inset 0px 1px 1px rgba(0,0,0,0.5), 0px 1px 0px rgba(255,255,255,.4);
    box-shadow: inset 0px 1px 1px rgba(0,0,0,0.5), 0px 1px 0px rgba(255,255,255,.4);

    background: -webkit-linear-gradient(top, #222 0%, #45484d 100%);
    background: -moz-linear-gradient(top, #222 0%, #45484d 100%);
    background: -o-linear-gradient(top, #222 0%, #45484d 100%);
    background: -ms-linear-gradient(top, #222 0%, #45484d 100%);
    background: linear-gradient(top, #222 0%, #45484d 100%);
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#222', endColorstr='#45484d',GradientType=0 );
}

.squaredThree label:after {
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
    filter: alpha(opacity=0);
    opacity: 0;
    content: '';
    position: absolute;
    width: 9px;
    height: 5px;
    background: transparent;
    top: 4px;
    left: 4px;
    border: 3px solid #fcfff4;
    border-top: none;
    border-right: none;

    -webkit-transform: rotate(-45deg);
    -moz-transform: rotate(-45deg);
    -o-transform: rotate(-45deg);
    -ms-transform: rotate(-45deg);
    transform: rotate(-45deg);
}

.squaredThree label:hover::after {
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=30)";
    filter: alpha(opacity=30);
    opacity: 0.3;
}

.squaredThree input[type=checkbox]:checked + label:after {
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
    filter: alpha(opacity=100);
    opacity: 1;
}

/* SQUARED FOUR */
.squaredFour {
    width: 20px;    
    margin: 20px auto;
    position: relative;
}

.squaredFour label {
    cursor: pointer;
    position: absolute;
    width: 20px;
    height: 20px;
    top: 0;
    border-radius: 4px;

    -webkit-box-shadow: inset 0px 1px 1px white, 0px 1px 3px rgba(0,0,0,0.5);
    -moz-box-shadow: inset 0px 1px 1px white, 0px 1px 3px rgba(0,0,0,0.5);
    box-shadow: inset 0px 1px 1px white, 0px 1px 3px rgba(0,0,0,0.5);
    background: #fcfff4;

    background: -webkit-linear-gradient(top, #fcfff4 0%, #dfe5d7 40%, #b3bead 100%);
    background: -moz-linear-gradient(top, #fcfff4 0%, #dfe5d7 40%, #b3bead 100%);
    background: -o-linear-gradient(top, #fcfff4 0%, #dfe5d7 40%, #b3bead 100%);
    background: -ms-linear-gradient(top, #fcfff4 0%, #dfe5d7 40%, #b3bead 100%);
    background: linear-gradient(top, #fcfff4 0%, #dfe5d7 40%, #b3bead 100%);
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#fcfff4', endColorstr='#b3bead',GradientType=0 );
}

.squaredFour label:after {
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
    filter: alpha(opacity=0);
    opacity: 0;
    content: '';
    position: absolute;
    width: 9px;
    height: 5px;
    background: transparent;
    top: 4px;
    left: 4px;
    border: 3px solid #333;
    border-top: none;
    border-right: none;

    -webkit-transform: rotate(-45deg);
    -moz-transform: rotate(-45deg);
    -o-transform: rotate(-45deg);
    -ms-transform: rotate(-45deg);
    transform: rotate(-45deg);
}

.squaredFour label:hover::after {
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=30)";
    filter: alpha(opacity=30);
    opacity: 0.5;
}

.squaredFour input[type=checkbox]:checked + label:after {
    -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
    filter: alpha(opacity=100);
    opacity: 1;
}

和简单的 html 代码：

<!-- Squared THREE -->
<div class="squaredThree">
    <input type="checkbox" value="None" id="squaredThree" name="check" />
    <label for="squaredThree">here is another label</label>
</div>

<!-- Squared FOUR -->
<div class="squaredFour">
    <input type="checkbox" value="None" id="squaredFour" name="check" />
    <label for="squaredFour">here is some label</label>
</div>

正如您在下面看到的 jsfiddle - 结果与预期相去甚远，标签在盒子上，但不在一行中。我能做些什么来修复它并以复选框标签（单行）的方式显示它？

Answer 1

需要从不允许文本流动的父 .squaredThree 和 .squaredFour 中移除宽度
pseudo 元素 :before 可用于为 checkbox background 添加样式而不是 label

body {
  background: #555;
}
input[type=checkbox] {
  visibility: hidden;
}
/* SQUARED THREE */

.squaredThree {
  margin: 20px auto;
  position: relative;
}
.squaredThree label {
  display: inline-block;
}
.squaredThree label:before {
  content: '';
  left: 0;
  cursor: pointer;
  position: absolute;
  width: 20px;
  height: 20px;
  top: 0;
  border-radius: 4px;
  -webkit-box-shadow: inset 0px 1px 1px rgba(0, 0, 0, 0.5), 0px 1px 0px rgba(255, 255, 255, .4);
