添加css渐变

Question

我使用此css代码在jsf页面显示绿色背景：

.container{
    background:-webkit-gradient(linear, left top, left bottom, color-stop(0, #5fa309), color-stop(1, #3b8018));
    background:-webkit-linear-gradient(top, #5fa309 0%, #3b8018 100%);
    background:-moz-linear-gradient(top, #5fa309 0%, #3b8018 100%);
    background:-o-linear-gradient(top, #5fa309 0%, #3b8018 100%);
    background:-ms-linear-gradient(top, #5fa309 0%, #3b8018 100%);
    background:linear-gradient(top, #5fa309 0%, #3b8018 100%);
    position:relative;
    display:inline-block;
    padding:0 20px 0 10px;
    width:270px;
    line-height:20px;
    font-size:12px;
    font-family:sans-serif;
    text-shadow:0 1px 0 #264400;
    font-weight:bold;
    color:#fff
}
.container:after{
    content:'';
    background:-webkit-gradient(linear, left top, right bottom, color-stop(0, #5fa309), color-stop(1, #3b8018));
    background:-webkit-linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    background:-moz-linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    background:-o-linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    background:-ms-linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    background:linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    position:absolute;
    top:3px;
    right:-7px;
    width:15px;
    height:15px;
    -webkit-transform:rotate(45deg);
    -moz-transform:rotate(45deg);
    -o-transform:rotate(45deg);
    -ms-transform:rotate(45deg);
    transform:rotate(45deg)
}

我很感兴趣如何在最后添加这种白色效果：

纯css有可能吗？

Answer 1

你可以使用众多CSS梯度生成器中的一个非常接近。这是我从ColorZilla生成的：

background: #b4df5b; /* Old browsers */
background: -moz-linear-gradient(45deg,  #b4df5b 40%, #ffffff 89%); /* FF3.6+ */
background: -webkit-gradient(linear, left bottom, right top, color-stop(40%,#b4df5b), color-stop(89%,#ffffff)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(45deg,  #b4df5b 40%,#ffffff 89%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(45deg,  #b4df5b 40%,#ffffff 89%); /* Opera 11.10+ */
background: -ms-linear-gradient(45deg,  #b4df5b 40%,#ffffff 89%); /* IE10+ */
background: linear-gradient(45deg,  #b4df5b 40%,#ffffff 89%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#b4df5b', endColorstr='#ffffff',GradientType=1 ); /* IE6-9 fallback on horizontal gradient */

如果您需要更接近目标，则必须优化渐变。为了使背景在所有浏览器中看起来完全相同，背景图像是您最好的选择。
