Detailed explanation of the use of writing-mode in css

When I use p{writing-mode:tb-rl;} when making a web page, the Chinese characters displayed on the page are solid and displayed normally, but when I make my school network , add this code *textrea{writing-mode:tb-rl;} to my graffiti board. I hope my message board will be stable, but the result is that the words are arranged firmly, but when I look at them, they are lying down, that is Chinese characters are rotated 90 degrees clockwise. Why is this and what should be done?

The writing-mode attribute has two values, lr-tb and tb-rl. The former is the default left-right, top-bottom, and the latter is top-bottom, right-left.

For example:

p{
writing-mode: tb-rl;
}

can be combined with direction typesetting.

Run code box

<style>
p{
writing-mode: tb-rl;
}
</style>
<p>

The bullet symbols in CSS include disc (solid dot), circle (hollow circle), square (solid square), decimal (Arabic numeral), lower-roman (lowercase Roman numerals), upper-roman (uppercase Roman numerals), lower-alpha (lowercase English letters), upper-alpha (uppercase English letters), none (none). For example, set the bullets of a list (ul or ol) to squares, such as:

li{
list-style: square;
}

In addition, list-style also has some values. For example, you can use some small pictures as bullets, Just write the url ("image address") directly under list-style. Note that if the left outer patch (margin-left) of an item list is set to zero, the list-style-position: outside (default is outside) bullet will not be displayed. . Unfortunately, the above-mentioned bullets do not seem to be able to set the size, and the dots and squares are always the same. And the vertical alignment cannot be set

lr-tb: Default value. The content of the object flows horizontally from left to right, with the next row below the previous row. All glyphs are vertical and upward. This layout is used in Roman languages ​​
tb-rl: up-down, right-left. Content in an object flows vertically from top to bottom and from right to left. The next vertical row is to the left of the previous vertical row. Full-width characters are pointed vertically upward, and half-width characters such as Latin letters or katakana are rotated 90 degrees clockwise. This layout is commonly used in East Asian languages ​​

Description:
Sets or retrieves the inherent writing direction of the object's content block. Western languages ​​do use left-right, top-bottom writing. But Asian languages ​​often have up-down, right-left writing styles.
When the value of this attribute changes, the effects of the text-align attribute and the vertical-align attribute will also change.
For the following elements, style sheet attributes are not inheritable:
BUTTON CAPTION INPUT INPUT type=button INPUT type=file INPUT type=password INPUT type=reset INPUT type=submit INPUT type=text ISINDEX OPTION TEXTAREA

The effect of this attribute will not be cumulative. For example, if the value of this property of the parent object is set to tb-rl, setting the value of this property of the child object to tb-rl will not cause the rotation of the child object.
If the object's writing-mode property setting is different from its parent object, it will get its own layout. The width of such an object is determined by using the height of its first laid-out parent.
When you use objects with different writing-mode property values, specifying certain sizes for each object gives you better overall control over their layout.
This property is read-only for the currentStyle object. For other objects can be read and written.
The corresponding script feature is writingMode.

Example of vertical layout of text:

.verticle-mode {   
    writing-mode: tb-rl;   
    -webkit-writing-mode: vertical-rl;         
    writing-mode: vertical-rl;   
}   
/* IE7比较弱，需要做点额外的动作 */  
.verticle-mode {   
    *width: 120px;   
}   
.verticle-mode h4,   
.verticle-mode p {   
    *display: inline;   
    *writing-mode: tb-rl;   
}   
.verticle-mode h4 {   
    *float:rightright;   
}

html is as follows:

<div class="verticle-mode">  
    <h4 id="咏柳">咏柳</h4>  
    <p>碧玉妆成一树高，<br>万条垂下绿丝绦。<br>不知细叶谁裁出，<br>二月春风似剪刀。</p>  
</div>
