- <h3>法则五<strong>(重要)</strong>:非同辈元素,任意一者或其祖元素拥有动态定位时,同时各自向上寻找动态定位的祖元素至共有的祖元素的下一级为止,并分别从中拿出具备最高级别的祖元素(或其本身)进行比较。</h3>
- <p>情况1:子元素的z-index无论多大,父元素大者居上。<p>
- <div class="parentDiv1" style="position:relative; z-index:2;">
- .parentDiv1{position:relative;<strong>z-index:2</strong>}
- <div class="div1">.div1{position:static}</div>
- </div>
- <div class="parentDiv2" style="position:relative; z-index:1;">
- <div class="div2" style="position:relative; z-index:10000;">.div2{position:relative;<strong>z-index:10000</strong>}</div>
- .parentDiv2{position:relative;<strong>z-index:1</strong>}
- </div>
- <p>情况2:父元素居下,子元素也可以居上。<p>
- <div class="parentDiv1">
- .parentDiv1{position:staitc}
- <div class="div1" style="position:relative;">.div1{position:relative}</div>
- </div>
- <div class="parentDiv2">
- <div class="div2">.div2{position:staitc}</div>
- .parentDiv2{position:staitc}
- </div>
- <p>情况1、情况2结合扩展比较。<p>
- <div class="grandDiv1" style="position:relative; z-index:3;">
- .grandDiv1{position:relative;<strong>z-index:3</strong>}
- <div class="parentDiv1">
- .parentDiv1{position:staitc}
