Huddle lading page | HTML, SCSS | Gradient animated button

First time using SVG's and struggled to make them respond to screen width, especially the illustration. Can you let me know if my use of SVG's is good or how I could improve on it?

Tried yet another animation, this time decided to animate the button with a gradient "breathing" animation.

Once <810px and making the screen smaller and smaller the illustration gains top and bottom margin and not sure how to fix to stop it from pushing the text down.

Also, in these challenges when it says "Desktop: 1440px" width in the README.md should I be doing max-width:1440px on the body to mimic the design?
