manage landing page challenge

What challenges did you encounter, and how did you overcome them?

1. setting the correct dimensions for each background pattern proves quite a challenge
2. changing an svg fill when i use it as an image src, still not sure how to do that, i can change the fill manually, but to do so, i need to use the svg base code , not assign them to a variable to import it
3. still can't achieve pixel perfect solution in regards to the design challenge

any feedback is greatly appreciated!
