How can I show the Description in Metadata on the top of my page?

Just like the official website. Thank you.

Unfortunately I'm not sure what you're trying to achieve, can you please further describe what you're trying to do?

[Tyxiang]

Thank you for your attention. I want to implement the layout in the picture:

I found that the contents of part A and part C come from the Metadata in the .md file.

You can access a page's meta data (e.g. the page's description) in your Twig template using {{ meta.description }}.
