web 页面开发常见问题

1.div溢出部分可滚动查看 且不显示滚动条

.box {
  position: relative;
  float: left;
  width: auto;
  width: 960px;
  height: 650px;
  overflow:auto;
  margin-left: 0 !important;
}
.box::-webkit-scrollbar {
  display: none;
}

2.跳出iframe

<script type="text/javascript">
    if (window != top) {
        top.location.href = location.href;
    }
</script>
