Answer 2

rotate + overflow会做（使用额外的元素或伪）：

＆＃13;

＆＃13;

.tr {
  height:40px;
  width:40px;
  overflow:hidden;
  transform:scale(1,1.2);/* increase visual height */
  }
.tr div {/* could be a pseudo */
  width:70%;
  height:70%;
  float:right;
  background:#C20009;
  transform:rotate(-45deg);
  box-shadow: 0 0 1px, inset 0 1px 1px , inset 5px -5px 5px rgba(0,0,0,0.3);
  transform-origin: top right;
  border-radius : 8px 0 0 0 /* and the rounded corner to finish */
  }

＆＃13;

<div class="tr">
  <div></div>
</div>

＆＃13;
