Utilities for controlling how flex and grid items are positioned along a container's main axis.
<div class="flex justify-start ...">
<div>1</div>
<div>2</div>
<div>3</div>
</div><div class="flex justify-center ...">
<div>1</div>
<div>2</div>
<div>3</div>
</div><div class="flex justify-end ...">
<div>1</div>
<div>2</div>
<div>3</div>
</div>Use justify-between to justify items along the container’s main axis such that there is an equal amount of space between each item:
<div class="flex justify-between ...">
<div>1</div>
<div>2</div>
<div>3</div>
</div>Use justify-around to justify items along the container’s main axis such that there is an equal amount of space on each side of each item:
<div class="flex justify-around ...">
<div>1</div>
<div>2</div>
<div>3</div>
</div>Use justify-evenly to justify items along the container’s main axis such that there is an equal amount of space around each item, but also accounting for the doubling of space you would normally see between each item when using justify-around:
<div class="flex justify-evenly ...">
<div>1</div>
<div>2</div>
<div>3</div>
</div>To justify flex items at a specific breakpoint, add a {screen}: prefix to any existing utility class. For example, use md:justify-between to apply the justify-between utility at only medium screen sizes and above.
<div class="justify-start md:justify-between ...">

默認情況下, 只有 響應式 的 justify-content 變化模式 (variants) 會產生。
在 tailwind.config.js 的 variants 區塊中變更 justifyContent 屬性來決定有哪些變化模式會生成。
舉個例子來說，這個設定將會生成 響應式 和 hover 的變化模式。
// tailwind.config.js
module.exports = {
variants: {
extend: {
// ...
+ justifyContent: ['responsive', 'hover'],
}
}
}如果你不打算在專案中使用 justify-content 功能，可以在你的設定檔裡的 corePlugins 屬性中將 justifyContent 設定為 false 來停用功能：
// tailwind.config.js
module.exports = {
corePlugins: {
// ...
+ justifyContent: false,
}
}
