目前正在开始学习AstroJS。我正在研究来自 github 的模板,发现了这个
<Fragment>
标签并引用了 astro 文档,这表明它可以用于指令。我提供了下面的代码供参考。
<Fragment slot="title">
Free template for <span class="hidden xl:inline">creating websites with</span>
<span class="text-accent dark:text-white highlight"> Astro 4.0</span> + Tailwind CSS
</Fragment>
在这里我看到一个参数作为槽。所以我尝试查看 Fragment 的定义并进入这个文件
env.d.ts
/// <reference path="./client.d.ts" />
// Caution! The types here are only available inside Astro files (injected automatically by our language server)
// As such, if the typings you're trying to add should be available inside ex: React components, they should instead
// be inside `client.d.ts`
type Astro = import('./dist/@types/astro.js').AstroGlobal;
// We have to duplicate the description here because editors won't show the JSDoc comment from the imported type
// However, they will for its properties, ex: Astro.request will show the AstroGlobal.request description
/**
* Astro global available in all contexts in .astro files
*
* [Astro documentation](https://docs.astro.build/en/reference/api-reference/#astro-global)
*/
declare const Astro: Readonly<Astro>;
declare const Fragment: any;
declare module '*.html' {
const Component: (opts?: { slots?: Record<string, string> }) => string;
export default Component;
}
在这里我没有看到任何插槽参数,但它为什么起作用。目前,插槽是标题,字体也很大,但如果是副标题,字体大小会减小。我也没有看到任何带有
title
的顺风声明。
我已经提供了tailwind.config.cjs
文件
import defaultTheme from 'tailwindcss/defaultTheme';
import typographyPlugin from '@tailwindcss/typography';
module.exports = {
content: ['./src/**/*.{astro,html,js,jsx,json,md,mdx,svelte,ts,tsx,vue}'],
theme: {
extend: {
colors: {
primary: 'var(--aw-color-primary)',
secondary: 'var(--aw-color-secondary)',
accent: 'var(--aw-color-accent)',
default: 'var(--aw-color-text-default)',
muted: 'var(--aw-color-text-muted)',
},
fontFamily: {
sans: ['var(--aw-font-sans, ui-sans-serif)', ...defaultTheme.fontFamily.sans],
serif: ['var(--aw-font-serif, ui-serif)', ...defaultTheme.fontFamily.serif],
heading: ['var(--aw-font-heading, ui-sans-serif)', ...defaultTheme.fontFamily.sans],
},
},
},
plugins: [typographyPlugin],
darkMode: 'class',
};
有人可以解释一下吗?还提供了回购链接
slot
组件上的 Fragment
属性指定 哪个插槽 Fragment
应在 Hero
组件中渲染。
Hero
组件,我们会看到:
const {
id,
title = await Astro.slots.render('title'),
subtitle = await Astro.slots.render('subtitle'),
tagline,
content = await Astro.slots.render('content'),
actions = await Astro.slots.render('actions'),
image = await Astro.slots.render('image'),
} = Astro.props;
---
…
{
title && (
<h1
class="text-5xl md:text-6xl font-bold leading-tighter tracking-tighter mb-4 font-heading dark:text-gray-200"
set:html={title}
/>
)
}
<div class="max-w-3xl mx-auto">
{subtitle && <p class="text-xl text-muted mb-6 dark:text-slate-300" set:html={subtitle} />}
所以如果我们有
slot="title"
,我们会看到:
<h1
class="text-5xl md:text-6xl font-bold leading-tighter tracking-tighter mb-4 font-heading dark:text-gray-200"
>
Free template for <span class="hidden xl:inline">creating websites with</span>
<span class="text-accent dark:text-white highlight"> Astro 4.0</span> + Tailwind CSS
</h1>
如果我们有
slot="subtitle"
,我们会看到:
<p class="text-xl text-muted mb-6 dark:text-slate-300">
Free template for <span class="hidden xl:inline">creating websites with</span>
<span class="text-accent dark:text-white highlight"> Astro 4.0</span> + Tailwind CSS
<p>
因此,
slot="title"
的文本更大,因为 Fragment
内的元素在 HTML 标记内呈现,该 HTML 标记使用 text-5xl md:text-6xl
指定更大的字体大小。而对于 slot="title"
,元素将在具有 text-xl
(字体较小)的 HTML 标签内呈现。
