示例(Examples)
¥Examples
拉紧(Stretch)
¥Stretch
使用 items-stretch 工具拉伸网格项以填充容器的横轴：
¥Use the items-stretch utility to stretch items to fill the container's cross axis:
<div class="flex items-stretch ..."> <div class="py-4">01</div> <div class="py-12">02</div> <div class="py-8">03</div></div>开始(Start)
¥Start
使用 items-start 工具将项目与容器横轴的起点对齐：
¥Use the items-start utility to align items to the start of the container's cross axis:
<div class="flex items-start ..."> <div class="py-4">01</div> <div class="py-12">02</div> <div class="py-8">03</div></div>中心(Center)
¥Center
使用 items-center 工具将项目沿容器横轴的中心对齐：
¥Use the items-center utility to align items along the center of the container's cross axis:
<div class="flex items-center ..."> <div class="py-4">01</div> <div class="py-12">02</div> <div class="py-8">03</div></div>结尾(End)
¥End
使用 items-end 工具将项目与容器横轴的末端对齐：
¥Use the items-end utility to align items to the end of the container's cross axis:
<div class="flex items-end ..."> <div class="py-4">01</div> <div class="py-12">02</div> <div class="py-8">03</div></div>基线(Baseline)
¥Baseline
使用 items-baseline 工具沿容器的横轴对齐项目，使其所有基线都对齐：
¥Use the items-baseline utility to align items along the container's cross axis such that all of their baselines align:
<div class="flex items-baseline ..."> <div class="pt-2 pb-6">01</div> <div class="pt-8 pb-12">02</div> <div class="pt-12 pb-4">03</div></div>最后基线(Last baseline)
¥Last baseline
使用 items-baseline-last 工具沿容器的横轴对齐项目，使其所有基线都与容器中的最后一条基线对齐：
¥Use the items-baseline-last utility to align items along the container's cross axis such that all of their baselines align with the last baseline in the container:

<div class="grid grid-cols-[1fr_auto] items-baseline-last"> <div> <img src="img/spencer-sharp.jpg" /> <h4>Spencer Sharp</h4> <p>Working on the future of astronaut recruitment at Space Recruit.</p> </div> <p>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.
