Shapes of color like datacamp.com

How would one go about designing a website that has shapes of color like www.datacamp.com?


Here is my site Read-Only: LINK
(how to share your site Read-Only link)

All of the colored shapes look to be SVGs that are positioned on the edges of the different sections, but for some of the more simple rectangular shapes I’d imagine you could use CSS Grid to create a matrix of colors.

Is there a particular design from the linked site that you’re looking to mimic?
