How to Create a Dashboard Similar to the Screenshot

[Samuraiflamesf]

Hello,
I am like to create a dashboard similar to the one shown in the attached screenshot.

As you can see at:
https://github.com/Samuraiflamesf/CofreObisidian/tree/main/src/site/styles/user
I have already added the code in scss and also tested it in css, to check if it is working. As you can see, one of them is working, accessing the site: http://cofreobisidian.netlify.app/
I put the cssclasses property in the code: dashboard and in the settings I put "cssclasses" by default

Could you please provide guidance on how to achieve this? Any tips on libraries, frameworks, or design principles that could help would be greatly appreciated.

Thank you for your assistance!
