示例(Examples)
¥Examples
基本示例(Basic example)
¥Basic example
使用 top-<number>
、right-<number>
、bottom-<number>
、left-<number>
和 inset-<number>
工具(如 top-0
和 bottom-4
)设置 定位元素 的水平或垂直位置:
¥Use top-<number>
, right-<number>
, bottom-<number>
, left-<number>
, and inset-<number>
utilities like top-0
and bottom-4
to set the horizontal or vertical position of a positioned element:
<!-- Pin to top left corner --><div class="relative size-32 ..."><div class="absolute top-0 left-0 size-16 ...">01</div></div><!-- Span top edge --><div class="relative size-32 ..."><div class="absolute inset-x-0 top-0 h-16 ...">02</div></div><!-- Pin to top right corner --><div class="relative size-32 ..."><div class="absolute top-0 right-0 size-16 ...">03</div></div><!-- Span left edge --><div class="relative size-32 ..."><div class="absolute inset-y-0 left-0 w-16 ...">04</div></div><!-- Fill entire parent --><div class="relative size-32 ..."><div class="absolute inset-0 ...">05</div></div><!-- Span right edge --><div class="relative size-32 ..."><div class="absolute inset-y-0 right-0 w-16 ...">06</div></div><!-- Pin to bottom left corner --><div class="relative size-32 ..."><div class="absolute bottom-0 left-0 size-16 ...">07</div></div><!-- Span bottom edge --><div class="relative size-32 ..."><div class="absolute inset-x-0 bottom-0 h-16 ...">08</div></div><!-- Pin to bottom right corner --><div class="relative size-32 ..."><div class="absolute right-0 bottom-0 size-16 ...">09</div></div>
使用负值(Using negative values)
¥Using negative values
要使用负顶部/右侧/底部/左侧值,请在类名前加上破折号以将其转换为负值类名前面加上破折号,将其转换为负值:
¥To use a negative top/right/bottom/left value, prefix the class name with a dash to convert it to a negative value:
<div class="relative size-32 ..."><div class="absolute -top-4 -left-4 size-14 ..."></div></div>
使用逻辑属性(Using logical properties)
¥Using logical properties
使用 start-<number>
或 end-<number>
工具(如 start-0
和 end-4
)设置 inset-inline-start
和 inset-inline-end
逻辑属性,它们根据文本方向映射到左侧或右侧:
¥Use start-<number>
or end-<number>
utilities like start-0
and end-4
to set the inset-inline-start
and inset-inline-end
logical properties, which map to either the left or right side based on the text direction:
Left-to-right
Right-to-left
<div dir="ltr"><div class="relative size-32 ..."> <div class="absolute start-0 top-0 size-14 ..."></div></div><div> <div dir="rtl"> <div class="relative size-32 ..."> <div class="absolute start-0 top-0 size-14 ..."></div> </div> <div></div> </div></div></div>
要获得更多控制,你还可以使用 LTR 和 RTL 修饰符 根据当前文本方向有条件地应用特定样式。
¥For more control, you can also use the LTR and RTL modifiers to conditionally apply specific styles depending on the current text direction.
使用自定义值(Using a custom value)
¥Using a custom value
使用工具例如 inset-[<value>]
and top-[<value>]
根据完全自定义的值设置 position:
<div class="inset-[3px] ..."> <!-- ... --></div>
对于 CSS 变量,还可以使用 inset-(<custom-property>)
语法:
<div class="inset-(--my-position) ..."> <!-- ... --></div>
这只是简写,用于 inset-[var(<custom-property>)]
它会自动为你添加 var()
函数。
响应式设计(Responsive design)
¥Responsive design
前缀 inset
,inset-x
,inset-y
,start
,end
,top
,left
,bottom
, and right
工具 使用断点变体如 md:
仅在 medium 屏幕尺寸及以上时应用工具:
<div class="top-4 md:top-6 ..."> <!-- ... --></div>
请参阅 变体文档 详细了解如何使用变体。
自定义主题(Customizing your theme)
¥Customizing your theme
该 inset-<number>
,inset-x-<number>
,inset-y-<number>
,start-<number>
,end-<number>
,top-<number>
,left-<number>
,bottom-<number>
, and right-<number>
工具由 --spacing
主题变量驱动,可以在你自己的主题中进行自定义:
@theme { --spacing: 1px; }
在主题变量文档中了解有关自定义间距比例的更多信息。
