Want to Create a Profile website Using Astra.

Hi, I need some help.

So I want to create a website that will have my portfolio card which I got from here – https://xcattx.com/css-profile-cards/, at the top of my website and just below it I want my blog posts to show. Now how can I do that using Astra.

I want to use that portfolio card at top then the blog posts, I don’t need the header btw.
