直接上 CSS 代码

a {
    display: inline-block;
    color: #404040;
    text-decoration: none;
    overflow: hidden;
    position: relative;
}

a::before {
	content: attr(data-letters);
	color: #f34540;
	width: 0;
	background: #fff;
	overflow: hidden;
	position: absolute;
	top: 0;
	left: 0;
	z-index: 2;
	white-space: nowrap;
	transition: width .5s;
}

a:hover::before{
	width: 100%;
	transition: width .5s;
}

然后就是 HTML 范例
