css example (1)-week picker

I try to find place to share some css snips, but most of them are needed to pay. So I just share them here, and then you can use jsfiddle or codepen to see its result.

CSS part:

.week-picker-fieldset {
 display: inline-block;
 padding: 0 7px;
 /* background: rgba(0, 0, 0, 0.4); */
 border-radius: 5px;
 -webkit-box-shadow: inset 0 0 0 1px rgba(0, 0, 0, 0.7), inset 0 2px 2px rgba(0, 0, 0, 0.3), 0 1px rgba(255, 255, 255, 0.1);
 box-shadow: inset 0 0 0 1px rgba(0, 0, 0, 0.7), inset 0 2px 2px rgba(0, 0, 0, 0.3), 0 1px rgba(255, 255, 255, 0.1);
}

.week-picker-nav {
 width: 25px;
 font-size: 16px;
 font-weight: bold;
 color: rgba(0, 0, 0, 0.7);
 text-align: center;
 text-decoration: none;
 text-shadow: 0 1px rgba(255, 255, 255, 0.1);
}

.week-picker-label, .week-picker-nav {
 display: inline-block;
 font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif;
 line-height: 25px;
 vertical-align: top;
 cursor: pointer;
}

.week-picker {
 margin: 100px auto;
 width: 600px;
 text-align: center;
}

.week-picker-fieldset > input {
 position: absolute;
 clip: rect(1px, 1px, 1px, 1px);
}

.week-picker-label, .week-picker-label:before {
 -webkit-transition: 0.15s ease-out;
 -moz-transition: 0.15s ease-out;
 -o-transition: 0.15s ease-out;
 transition: 0.15s ease-out;
}

.week-picker-label {
 position: relative;
 padding: 0 7px;
 font-size: 12px;
 font-weight: 200;
 color: #8d8ba6;
 text-transform: uppercase;
}

input:checked + .week-picker-label {
 color: white;
 background: #302e42;
 background-image: -webkit-linear-gradient(top, #302e42, #29253b);
 background-image: -moz-linear-gradient(top, #302e42, #29253b);
 background-image: -o-linear-gradient(top, #302e42, #29253b);
 background-image: linear-gradient(to bottom, #302e42, #29253b);
}

input:checked + .week-picker-label:before {
 opacity: 1;
}

.week-picker-label:before {
 content: '';
 position: absolute;
 top: -2px;
 bottom: -2px;
 left: -2px;
 right: -2px;
 border: 2px solid;
 border-color: #e4e0fb #b6b1d1 #b6b1d1;
