Relatively positioned and statically positioned elements will appear earlier in the HTML and have higher priority. 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;
}

2. Use natural flow layout: Natural flow layout means that elements are arranged in the order and position they appear in the HTML code, following the flow of the document characteristics. This layout is friendly to search engines and improves user experience.

}

  float: left;
}

3. Use media queries for responsive layout: Responsive layout allows the website to display well on different devices. When using media queries, try to avoid using absolute positioning of elements and instead use relative positioning or natural flow layout.

.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;
  }
}

4. 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;
}
