border: 1px solid #000;
text-align: center;
font-size: 16px;

<div class="outer"> <div class="inner1">这是内部容器1</div> <div class="inner2">这是内部容器2</div> </div>
In the above code, the two elements "inner container 1" and "inner container 2" are both included in the "outer container", where the "outer container" is defined with class outer div elements, while "inner container 1" and "inner container 2" use div elements with classes inner1 and inner2.
