Svg for web usage!

Hey guys i am trying to create an svg file with many shapes, which helps me animate the shapes using css but after i save my work as SVG and try to set width and height of it to 100% 100% in CSS it won’t scale, any idea how to create an svg that scale with height and width?

May I ask you to send me the project files in the DMs? You can just reply to my message there.
