设置某一个角的圆角,比如设置左上角的圆角:
border-top-left-radius:30px 60px;
同时分别设置四个角:
border-radius:30px 60px 120px 150px;
设置四个圆角相同:
border-radius:50%;
CSS3阴影
box-shadow:h-shadow v-shadow blur spread color inset;
分别设置阴影:水平偏移 垂直偏移 羽化大小 扩展大小 颜色 是否内阴影
<style type="text/css">
.box{
width:200px;
height:50px;
background-color:gold;
/* box-shadow:10px 10px 5px 2px pink inset; */
box-shadow:10px 10px 5px 2px pink;
}
</style>

<div class="box"></div>
<!-- 给盒子加上了粉红色的阴影 -->
rgba(新的颜色值表示法)
