Brwoser support: https://caniuse.com/?search=Logical%20Properties%20

 

We want to achieve following effect, the first box, we applied writing-mode: vertical-lr in order to get second box.

From the code, you can see that we have to change the second box widht & height

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
    <style>
      .box1 {
        border: 1px black solid;
        width: 300px;
        height: 100px;
      }
      .box1 div {
        border: 1px red solid;
        float: left;
        margin-left: 30px;
      }

      .box2 {
        border: 1px black solid;
        width: 100px;
        height: 300px;
        writing-mode: vertical-lr;
      }
      .box2 div {
        border: 1px red solid;
        float: left;
        margin-top: 30px;
      }
    </style>
  </head>
  <body>
    <h2>Logical Properties (逻辑属性)</h2>
    <div class="box1">
      <div>hello world</div>
      <div>hello world</div>
    </div>
    <div class="box2">
      <div>hello world</div>
      <div>hello world</div>
    </div>
  </body>
</html>

 

We can use margin-inline-start & block-size, inline-sizeto achieve the same effect

block-size: Y of text

inline-size: X of text

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
    <style>
      .box3 {
        border: 1px black solid;
        block-size: 100px;
        inline-size: 300px;
      }
      .box3 div {
        border: 1px red solid;
        float: left;
        margin-inline-start: 30px;
      }

      .box4 {
        border: 1px black solid;
        block-size: 100px;
        inline-size: 300px;
        writing-mode: vertical-lr;
      }
      .box4 div {
        border: 1px red solid;
        float: left;
        margin-inline-start: 30px;
      }
    </style>
  </head>
  <body>
    <h2>Logical Properties (逻辑属性)</h2>
    <div class="box3">
      <div>hello world</div>
      <div>hello world</div>
    </div>
    <div class="box4">
      <div>hello world</div>
      <div>hello world</div>
    </div>
  </body>
</html>
