示例
自动对齐
使用 self-auto 工具类根据容器的 align-items 属性值来对齐项目：
01
02
03
<div class="flex items-stretch ..."> <div>01</div> <div class="self-auto ...">02</div> <div>03</div></div>起始对齐
使用 self-start 工具类将项目对齐到容器交叉轴的起始位置，不受容器 align-items 值的影响：
01
02
03
<div class="flex items-stretch ..."> <div>01</div> <div class="self-start ...">02</div> <div>03</div></div>居中对齐
使用 self-center 工具类可以使元素沿容器的交叉轴居中对齐，无论容器的 align-items 值如何设置：
01
02
03
<div class="flex items-stretch ..."> <div>01</div> <div class="self-center ...">02</div> <div>03</div></div>末端对齐
使用 self-end 工具类将项目对齐到容器交叉轴的末端，不受容器 align-items 值的影响：
01
02
03
<div class="flex items-stretch ..."> <div>01</div> <div class="self-end ...">02</div> <div>03</div></div>拉伸
使用 self-stretch 工具类将元素拉伸以填充容器的交叉轴，无视容器的 align-items 值：
01
02
03
<div class="flex items-stretch ..."> <div>01</div> <div class="self-stretch ...">02</div> <div>03</div></div>基线对齐
使用 self-baseline 工具类将元素对齐，使其基线与 flex 容器交叉轴的基线对齐：
01
02
03
<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>最后基线对齐
使用 self-baseline-last 工具类将项目沿容器的交叉轴对齐，使其基线与容器中的最后一条基线对齐：
<div class="grid grid-cols-[1fr_auto]"> <div> <img src="img/spencer-sharp.jpg" /> <h4>Spencer Sharp</h4> <p class="self-baseline-last">在 Space Recruit 致力于宇航员招募的未来工作。</p> </div> <p class="self-baseline-last">spacerecruit.com</p></div>这对于确保文本项目即使高度不同也能相互对齐非常有用。
响应式设计
Prefix an align-self utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:
<div class="self-auto md:self-end ..."> <!-- ... --></div>Learn more about using variants in the variants documentation.
