css3代码：
body { counter-reset: sum; } #a:checked { counter-increment: sum 64; } #b:checked { counter-increment: sum 16; } #c:checked { counter-increment: sum -32; } #d:checked { counter-increment: sum 128; } #e:checked { counter-increment: sum 4; } #f:checked { counter-increment: sum -8; } .sum::before { content: '= ' counter(sum); } /* the rest is just to make things PRetty */ body { margin: 32px; font: 700 32px/1 'Droid Sans' , sans-serif; color: #fff; background-color: #583f3f; } h1 { margin: 0 0 32px; font-size: 48px; } h2 { margin: 0 0 8px 8px; font-size: inherit; } section { margin-bottom: 16px; padding: 16px; border-radius: 4px; overflow: hidden; background-color: rgba(255, 255, 255, .1); } input { position: absolute; left: -9999px; } label { float: left; margin: 8px; padding: 16px; border-radius: 4px; border: solid 2px rgba(255, 255, 255, .4); background-color: rgba(255, 255, 255, .2); cursor: pointer; transition: all .1s; } label::before { display: inline; } input:checked + label { border: solid 2px #fff; background-color: rgba(255, 255, 255, .4); box-shadow: 0 0 10px #fff; } span { float: left; margin: 8px; padding: 18px; border-radius: 4px; background-color: rgba(0, 0, 0, .1); } #a:checked ~ #b:checked ~ #c:not(:checked) ~ #d:not(:checked) ~ #e:not(:checked) ~ #f:checked ~ .sum::after { content: ' (hooray!)'; }
