我如何使方框3对准方框2的右边？

Question

我正在尝试使“ this is box 3”（我的“这是方框3”）与父容器内的“ this is box 2”的右边对齐。方框3和方框2应该重叠并且彼此相邻吗？我尝试使用“ display：inline;但是不做任何事情。任何建议将不胜感激？

html {
  box-sizing: border-box;
}

*,
*:before,
*:after {
  box-sizing: inherit;
}

.container {
  width: 300px;
  height: 600px;
  border: 5px solid black;
  padding: 20px;
  margin: 0 auto;
}

.box1 {
  height: 50%;
  width: 90%;
  border: 1px solid black;
  padding-top: 10px;
  margin: 0 auto;
  text-align: center;
}

.box2 {
  height: 50%;
  width: 50%;
  border: 1px solid blue;
  text-align: center;
  margin-top: 10px;
}

.box3 {
  height: 50%;
  width: 50%;
  text-align: center;
  border: 1px solid red;
  float: right;
}

<div class="container">
  <div class="box1"> this is box 1 </div>
  <div class="box2"> this is box 2 </div>
  <div class="box3"> this is box 3 </div>
</div>

Answer 1

将float: left添加到.box2，将marign-top: 10px添加到.box3：

html {
  box-sizing: border-box;
}

*,
*:before,
*:after {
  box-sizing: inherit;
}

.container {
  width: 300px;
  height: 600px;
  border: 5px solid black;
  padding: 20px;
  margin: 0 auto;
}

.box1 {
  height: 50%;
  width: 90%;
  border: 1px solid black;
  padding-top: 10px;
  margin: 0 auto;
  text-align: center;
}

.box2 {
  height: 50%;
  width: 50%;
  border: 1px solid blue;
  text-align: center;
  margin-top: 10px;
  float: left;
}

.box3 {
  height: 50%;
  width: 50%;
  text-align: center;
  border: 1px solid red;
  float: right;
  margin-top: 10px;
}

<div class="container">
  <div class="box1"> this is box 1 </div>
  <div class="box2"> this is box 2 </div>
  <div class="box3"> this is box 3 </div>
</div>

Answer 2

您可以将display: flex与flex-wrap: wrap上的.container一起使用：

html {
  box-sizing: border-box;
}

*,
*:before,
*:after {
  box-sizing: inherit;
}

.container {
  display: flex;
  flex-wrap: wrap;
  justify-content: center;
  width: 300px;
  height: 600px;
  border: 5px solid black;
  padding: 20px;
  margin: 0 auto;
  text-align: center;
}

.box1 {
  height: 50%;
  width: 90%;
  border: 1px solid black;
  margin-bottom: 10px;
  padding-top: 10px;
}

.box2,
.box3 {
  height: 50%;
  width: 50%;
}

.box2 {
  border: 1px solid blue;
}

.box3 {
  border: 1px solid red;
}

<div class="container">
  <div class="box1"> this is box 1 </div>
  <div class="box2"> this is box 2 </div>
  <div class="box3"> this is box 3 </div>
</div>

您可以使用此代码

        body {
            margin: 0;
            padding: 0;
        }
        html {
            box-sizing: border-box;
        }
        *,
        *:before,
        *:after {
            box-sizing: inherit;
        }
        .container {
            width: 300px;
            height: 600px;
            border: 5px solid black;
            padding: 20px;
            margin: 0 auto;
        }
        .box1 {
            height: 50%;
            width:100%;
            border: 1px solid black;
            padding-top: 10px;
            margin: 0 auto;
            text-align: center;
        }
        .box2 {
            height: 50%;
            width: 50%;
            border: 1px solid blue;
            text-align: center;
            float: left;
        }
        .box3 {
            height: 50%;
            width: 50%;
            text-align: center;
            border: 1px solid red;
            float: right;
        }

    <div class="container">
        <div class="box1"> this is box 1 </div>
        <div class="box2"> this is box 2 </div>
        <div class="box3"> this is box 3 </div>
    </div>
