White diagonal splits?

Hey, is there a better way of making these kind of white diagonal splits on site?
I have just uploaded a picture on the background of the site which contains them and i am pretty sure there could be an better way to do this.

This is my first site created on webflow, so i think there will be other positioning/sizing issues also. Design of the site is neither ready :smiley:
