content: '';
position: absolute;
width: 1.2ex;
height: 0.4ex;
background: rgba(0, 0, 0, 0);
top: 0.9ex;
left: 0.4ex;
border: 3px solid blue;
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);
}
input[type="checkbox"] {
line-height: 2.1ex;
}
input[type="radio"],
input[type="checkbox"] {
position: absolute;
left: -999em;
}
input[type="checkbox"] + label {
position: relative;
overflow: hidden;
cursor: pointer;
}
input[type="checkbox"] + label::before {
content: "";
display: inline-block;
vertical-align: -25%;
