Responsive desktop first landing page using css grid

Hello!

• Can anyone, please, help me out with those icons? I simply copy pasted the .svg files and some work while other don't work. I really don't know how should I proceed.

• What do you think about that image which is positioned absolute at the top right corner? I put both the nav and hero under the header and positioned it relative to the header. Is there any other better solution?

• I'm curios if the html tags semantics are ok.

All feedback is greatly appreciated, thanks a lot
