i used html for structure and flex box and buttons for styling

• Semantic HTML You probably should be using link elements <a> instead of buttons for the social media links since you want them to take the user into another page.
• Font Size The other one is you should use the font size specified on the style guide for the paragraph elements.

Hello, I saw your code and there are some things you can take into account to improve your project, in the body, you can use min-height 100vh and center the container with flexbox.

Inside the container you can use the padding property to give more padding to the content, this way you would avoid using the height and width property. You can do it, keep it up.

I would also recommend using semantic html, it will make your code look clean and easy to understand.
