Question

我正在尝试在css中创建一个具有向内椭圆形状的div，就像this一样。

目前，我有一个向外而不是向内的形状（JS Fiddle Link）。

.shape {
float: left;
width: 100px;
height: 50px;
border: none;
background: #CC0000;
border-radius: 0 90px 0 0;
-moz-border-radius: 0 90px 0 0;
-webkit-border-radius: 0 90px 0 0;
background-image: -webkit-gradient( linear, left top, right bottom, color-stop(0, #520C0C), color-stop(1, #CC0000) );
background-image: -o-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
background-image: -moz-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
background-image: -webkit-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
background-image: -ms-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
background-image: linear-gradient(to right bottom, #520C0C 0%, #CC0000 100%);
}

关于如何解决这个问题的任何想法？

我为你创建了this fiddle。这是代码：

<强> HTML

<div class="container">
    <div class="shape"></div>
</div>

<强> CSS

.container {
float: left;
width: 100px;
height: 50px;
border: none;
background: #CC0000;
background-image: -webkit-gradient( linear, left top, right bottom, color-stop(0, #520C0C), color-stop(1, #CC0000) );
background-image: -o-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
background-image: -moz-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
background-image: -webkit-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
background-image: -ms-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
background-image: linear-gradient(to right bottom, #520C0C 0%, #CC0000 100%);
}
.shape {
width: 100px;
height: 50px;
border: none;
background: #000000;
border-radius: 0 0 0 90px;
-moz-border-radius: 0 0 0 90px;
-webkit-border-radius: 0 0 0 90px;
}

查看我的example fiddle。

我使用了一个伪元素和一些椭圆边框半径以及一个插入框阴影。

div {
    position:relative;
    width: 200px;height: 100px;
    background: #CC0000;
    background-image: linear-gradient(to right bottom, #520C0C 0%, #CC0000 100%);
}
div:after {
    position:absolute;content:"";
    width: 100%;height: 95%;
    background: #222;
    box-shadow:inset 10px -10px 5px -10px #000;
    border-radius: 0 0 0 200px / 100px;
}

稍加努力，可能会更接近你的结果，但这可能是一个很好的起点。

如果图形中“不存在”的部分不一定是透明的，那么你可以制作一个普通的矩形，然后建立一个弯曲的形状，它将位于矩形的顶部并具有与背景颜色相同。

http://jsfiddle.net/ub8fM/1/

.shape {
    float: left;
    width: 100px;
    height: 50px;
    border: none;
    background: #CC0000;
    background-image: -webkit-gradient(linear, left top, right bottom, color-stop(0, #520C0C), color-stop(1, #CC0000));
    background-image: -o-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
    background-image: -moz-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
    background-image: -webkit-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
    background-image: -ms-linear-gradient(right bottom, #520C0C 0%, #CC0000 100%);
    background-image: linear-gradient(to right bottom, #520C0C 0%, #CC0000 100%);
    position:relative;
}

.shape:before {
    border-radius: 0 90px 0 0;
    -moz-border-radius: 0 90px 0 0;
    -webkit-border-radius: 0 90px 0 0;
    content:'';
    position:absolute;
    top:0;
    left:0;
    background:white;
    width:100%;
    height:100%;
}

让影子变得更难，我还没有解决方案。
