图片裁剪

clip-path有四种裁剪方式：

1.矩形

2.圆形

3.椭圆

4.多边形

1.建议写百分比

2.用在线生成工具来裁剪

关于裁剪常用的应用场景：图片一开始展示的是裁剪后的结果。当鼠标hover以后，展示全部。

 <img class="img" src="https://gimg2.baidu.com/image_search/src=http%3A%2F%2Fsafe-img.xhscdn.com%2Fbw1%2Fd66671b7-b6c6-4e7f-ba50-f95b0b12a9fd%3FimageView2%2F2%2Fw%2F1080%2Fformat%2Fjpg&refer=http%3A%2F%2Fsafe-img.xhscdn.com&app=2002&size=f9999,10000&q=a80&n=0&g=0n&fmt=auto?sec=1702107078&t=dc9c5ceef37a4fc69c5807b1fca8f575"></img>.img{width:600px;height:600px;margin-left:30%;/*clip-path有四种裁剪方式：1.矩形2.圆形3.椭圆4.多边形1.建议写百分比2.用在线生成工具来裁剪*/clip-path:circle(50% at 50% 50%);transition:0.5s;}.img:hover{clip-path:circle(100% at 50% 50%) }

粘性布局

一句话：一个sticky元素会“固定”在离它【最近】的一个拥有“滚动机制”的祖先上。

针对像素点的操作

阴影效果
模糊程度
黑白效果
