#What custom components are you building for your Astro blogs?

I'm curious what kind of custom components you all use for your blog posts (like in your MDX files).

For my own setup, I recently built and started using a custom <Pullquote /> component to make specific text pop out in my articles.

What are your go-to components? Custom callouts, image galleries, specialized code blocks? I'd love to see what you've built and get some inspiration for my own site!

Hi @lilac quest. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

This looks like a community discussion question rather than a technical question I can answer from documentation. I'm an AI assistant specialized in Astro's technical documentation, so I can't share personal experiences or community opinions about what components people are building.

However, I can point you to what Astro's docs and Starlight cover regarding custom components in MDX, which might give you some inspiration:

Custom Components You Can Build for MDX Blog Posts

Replacing Standard HTML Elements

You can map Markdown syntax to custom components. For example, a custom <Blockquote> component: [MDX custom components]

---
const props = Astro.props;
---
<blockquote {...props} class="bg-blue-50 p-4">
  <span class="text-4xl text-blue-600 mb-2">"</span>
  <slot />
</blockquote>

Then in your MDX file:

import Blockquote from '../components/Blockquote.astro';
export const components = { blockquote: Blockquote }

> This quote will be a custom Blockquote

Your <Pullquote /> component would work similarly — just import and use it directly in MDX.

Passing Components via `<Content />`

You can also pass custom components (like a custom <h1>) when rendering MDX content collections: [passing components]

<Content components={{ h1: CustomHeading }} />

Starlight's Built-in Components for Inspiration

If you use Starlight, it ships with ready-made components like:

<Aside> — callouts/admonitions (note, tip, caution, danger) [Asides]
<Card> / <CardGrid> — content cards with optional icons [Cards]
<Code> — syntax-highlighted code blocks from external sources [Code component]

These can serve as great inspiration for building your own equivalents in a non-Starlight blog.

For community discussion and inspiration, I'd recommend checking out the Astro Discord or the Astro forums, where developers actively share what they've built!
