Absolutely positioned and fixedly positioned elements cannot be positioned until the HTML is parsed, which may lead to inaccurate weight evaluation of these elements by search engine crawlers.

  left: 20px;
}

.container {
  position: relative;
  width: 100%;
  max-width: 1200px;
  margin: 0 auto;
}

.box {
  position: relative;
  width: 100%;
}

@media (min-width: 768px) {
  .box {
    width: 50%;
    float: left;
  }
}
  1. Reasonable use of the z-index attribute: The z-index attribute is used to control the stacking order of elements. When using z-index, avoid covering key content under other elements to ensure that search engines can correctly read important content.

Sample code:

.container {
  position: relative;
  z-index: 1;
}

.overlay {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  background-color: rgba(0,0,0,0.5);
  z-index: 2;
}
