土豪金

绿色

background-image: -webkit-linear-gradient(left, #ffeef9, #ffb6c1 25%, #ffeef9 50%, #ffb6c1 75%, #ffeef9);
background-image: -webkit-linear-gradient(left, #e0f7fa, #b2dfdb 25%, #e0f7fa 50%, #b2dfdb 75%, #e0f7fa);

粉色

background-image: -webkit-linear-gradient(left, #ffeef9, #ffb6c1 25%, #ffeef9 50%, #ffb6c1 75%, #ffeef9);
background-image: -webkit-linear-gradient(left, #fb7299, #ffb6c1 25%, #fb7299 50%, #ffb6c1 75%, #fb7299);

为了兼容现代浏览器，除了 -webkit-linear-gradient（主要用于旧版Safari和Chrome）之外， 应该包括标准的 linear-gradient 属性，如下所示：

background-image: linear-gradient(to right, #ffeef9, #ffb6c1 25%, #ffeef9 50%, #ffb6c1 75%, #ffeef9);
