前段经常使用功能

破裂的图片

img {  
  /* Same as first example */
  min-height: 50px;
}

img:before {  
  content: " ";
  display: block;

  position: absolute;
  top: -10px;
  left: 0;
  height: calc(100% + 10px);
  width: 100%;
  background-color: rgb(230, 230, 230);
  border: 2px dotted rgb(200, 200, 200);
  border-radius: 5px;
}

img:after {  
  content: "\f127" " Broken Image of " attr(alt);
  display: block;
  font-size: 16px;
  font-style: normal;
  font-family: FontAwesome;
  color: rgb(100, 100, 100);

  position: absolute;
  top: 5px;
  left: 0;
  width: 100%;
  text-align: center;
}

长单词处理

.hyphenate {
    overflow-wrap: break-word;
    word-wrap: break-word;
    hyphens: auto;
}

图片自适应

图片等比例缩放自动适应img大小，可能留有空隙

img {
    object-fit: contain;
}

图片等比例缩放自动适应填充img大小，

img {
    object-fit: cover;
}

还有个none值，保持原有尺寸比例。同时保持替换内容原始尺寸大小。
