示例(Examples)
¥Examples
自动(Auto)
¥Auto
使用 self-auto
工具根据容器的 align-items
属性值对齐项目:
¥Use the self-auto
utility to align an item based on the value of the container's align-items
property:
<div class="flex items-stretch ..."><div>01</div><div class="self-auto ...">02</div><div>03</div></div>
开始(Start)
¥Start
使用 self-start
工具将项目与容器横轴的起始端对齐,无论容器的 align-items
值如何:
¥Use the self-start
utility to align an item to the start of the container's cross axis, despite the container's align-items
value:
<div class="flex items-stretch ..."><div>01</div><div class="self-start ...">02</div><div>03</div></div>
中心(Center)
¥Center
使用 self-center
工具将网格项与容器横轴的中心对齐,无论容器的 align-items
值如何:
¥Use the self-center
utility to align an item along the center of the container's cross axis, despite the container's align-items
value:
<div class="flex items-stretch ..."><div>01</div><div class="self-center ...">02</div><div>03</div></div>
结尾(End)
¥End
使用 self-end
工具将项目与容器横轴的末端对齐,无论容器的 align-items
值如何:
¥Use the self-end
utility to align an item to the end of the container's cross axis, despite the container's align-items
value:
<div class="flex items-stretch ..."><div>01</div><div class="self-end ...">02</div><div>03</div></div>
拉紧(Stretch)
¥Stretch
使用 self-stretch
工具拉伸网格项以填充容器的横轴,无论容器的 align-items
值如何:
¥Use the self-stretch
utility to stretch an item to fill the container's cross axis, despite the container's align-items
value:
<div class="flex items-stretch ..."><div>01</div><div class="self-stretch ...">02</div><div>03</div></div>
基线(Baseline)
¥Baseline
使用 self-baseline
工具将项目对齐,使其基线与弹性容器横轴的基线对齐:
¥Use the self-baseline
utility to align an item such that its baseline aligns with the baseline of the flex container's cross axis:
<div class="flex ..."><div class="self-baseline pt-2 pb-6">01</div><div class="self-baseline pt-8 pb-12">02</div><div class="self-baseline pt-12 pb-4">03</div></div>
最后基线(Last baseline)
¥Last baseline
使用使用 self-baseline-last
工具将项目沿容器的横轴对齐,使其基线与容器中的最后一个基线对齐:
¥Use the self-baseline-last
utility to align an item along the container's cross axis such that its baseline aligns with the last baseline in the container:
<div class="grid grid-cols-[1fr_auto]"><div> <img src="img/spencer-sharp.jpg" /> <h4>Spencer Sharp</h4> <p class="self-baseline-last">Working on the future of astronaut recruitment at Space Recruit.</p></div><p class="self-baseline-last">spacerecruit.com</p></div>
这对于确保文本项彼此对齐非常有用,即使它们的高度不同。
¥This is useful for ensuring that text items align with each other, even if they have different heights.
响应式设计(Responsive design)
¥Responsive design
在 align-self
工具前面使用断点变体如 md:
仅在 medium 屏幕尺寸及以上时应用工具:
<div class="self-auto md:self-end ..."> <!-- ... --></div>
