CSS文本方向 - 小火柴的蓝色理想

May 21, 2016 am 08:42 AM

前面的话

  一般地,正常网页文本方向都是从上到下,从左到右。实际上,有多种设置文本方向的属性,前面已经详细介绍过text-align,HTML全局属性中有一个"dir"属性就是专门用来设置文本方向的,设置文本方向的CSS样式有direction、unicode-bidi和writing-mode。本文将详细介绍网页文本方向的设置方法

 

text-align

  水平对齐实现上影响的是一个元素中的文本的水平对齐方式,关于text-align的详细信息移步至此

  值: left | center | right | justify | inherit

  初始值: left

  应用于: 块级元素(包括block和inline-block)

  继承性: 有

<span style="color: #008000;">//</span><span style="color: #008000;">left: 1 23 456
</span><span style="color: #008000;">//</span><span style="color: #008000;">right: 1 23 456</span>
Copy after login

 

writing-mode

  writing-mode原先是IE的私有属性,原先的属性是lr-tb(左-右,上-下)和tb-rl(上-下,右-左)。其中writing-mode:tb-rl常用于触发haslayout。但W3C将writing-mode属性标准化后,其属性值也发生了变化

  值: horizontal-tb | vertical-rl | vertical-lr

  初始值: horizontal-tb

  应用于: 除表格类元素之外的所有元素

  继承性: 有

  [注意]safari和移动端IOS和android需要添加-webkit-前缀;IE浏览器只支持自己的私有属性值

  [注意]设置writing-mode时,text-align属性失效

 

dir

  dir是HTML的全局属性,专门用来设置文本的方向

  值: ltr | rtl | auto

<span style="color: #008000;">//</span><span style="color: #008000;">ltr: 1 23 456
</span><span style="color: #008000;">//</span><span style="color: #008000;">rtl: 456 23 1</span>
Copy after login
Copy after login

 

direction

  direction是设置文本方向的CSS样式

  值: ltr | rtl | inherit

  初始值: ltr

  应用于: 所有元素

  继承性: 有

  [注意]想让direction样式在inline元素上起作用,需要unicode-bidi样式的相关设置

  [注意]设置direction样式时,HTML元素的全局属性dir无效

<span style="color: #000000;">ltr: 从左到右(left to right)
rtl: 从右到左(right to left)</span>
Copy after login
<span style="color: #008000;">//</span><span style="color: #008000;">ltr: 1 23 456
</span><span style="color: #008000;">//</span><span style="color: #008000;">rtl: 456 23 1</span>
Copy after login

unicode-bidi

  unicode-bidi是一种更健壮的处理文本方向的方式

  值: normal | embed | bidi-override | isolate | isolate-override | plaintext | inherit

  初始值: normal

  应用于: 所有元素

  继承性: 无

  [注意]unicode-bidi属性应用于flex弹性盒模型上有问题,除非伸缩容器只包含一个匿名伸缩项目时有效,其余情况都无效

  [注意]isolate、isolate-override、plaintext是实验属性值,几乎没有浏览器支持

<span style="color: #008000;">//</span><span style="color: #008000;">display:inline-block/block</span>
normal/embed: <span style="color: #800080;">456</span> <span style="color: #800080;">23</span> <span style="color: #800080;">1</span><span style="color: #000000;">
bidi</span>-<span style="color: #0000ff;">override</span>: <span style="color: #800080;">654</span> <span style="color: #800080;">32</span> <span style="color: #800080;">1</span>

<span style="color: #008000;">//</span><span style="color: #008000;">display:inline</span>
normal:<span style="color: #800080;">1</span> <span style="color: #800080;">23</span> <span style="color: #800080;">456</span><span style="color: #000000;">
embed: </span><span style="color: #800080;">456</span> <span style="color: #800080;">23</span> <span style="color: #800080;">1</span><span style="color: #000000;">
bidi</span>-<span style="color: #0000ff;">override</span>: <span style="color: #800080;">654</span> <span style="color: #800080;">32</span> <span style="color: #800080;">1</span>
Copy after login

  [注意]只有当dir为rtl或direction为rtl时,unicode-bidi属性才起作用
