纯css实现3D字体

下面分别是html，css和js代码：

<div class="wrapper">
    <h1 contenteditable data-heading="Folded">Folded</h1>
</div>

$bg: #e6e2df;

html, body {
    height: 100%;
}

body {
    background: linear-gradient(45deg, $bg 80%,#c2c1bd 100%);
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
}

.wrapper {
    width: 100%;
    font-family: 'Source Code Pro', monospace;
    margin: 0 auto;
    height: 100%;

    h1 {
        text-transform: uppercase;
        transform: translate(-50%, -50%) skew(10deg) rotate(-10deg);
        font-size: 20vw;
        top: 50%;
        left: 50%;
        margin:;
        position: absolute;
        text-rendering: optimizeLegibility;
        font-weight:;
        color: rgba(#ff9eb1, 0.5);
        text-shadow: 1px 4px 6px $bg, 0 0 0 #66303a, 1px 4px 6px $bg;
        white-space: nowrap;

        &:before {
            content: attr(data-heading);
            position: absolute;
            left:;
            top: -4.8%;
            overflow: hidden;
            width: 100%;
            height: 50%;
            color: #fbf7f4;
            transform: translate(1.6vw, 0) skew(-13deg) scale(1, 1.2);
            z-index:;
            text-shadow: 2px -1px 6px rgba(0,0,0,0.2);
        }

        &:after {
            content: attr(data-heading);
            position: absolute;
            left:;
            top:;
            overflow: hidden;
            width: 100%;
            height: 100%;
            z-index:;
            color: #d3cfcc;
            transform: translate(0vw, 0) skew(13deg) scale(1, 0.8);
            clip-path: polygon(0 50%, 100% 50%, 100% 100%, 0% 100%);
            text-shadow: 2px -1px 6px rgba(0,0,0,0.3);
        }
    }
}

// JS for content editable trick from Chris Coyier

var h1 = document.querySelector("h1");

h1.addEventListener("input", function() {
  this.setAttribute("data-heading", this.innerText);
});
