What I have learned:
I learned Resolution Switching: A given Image in a mobile First Approach switches to another source on another resolution.
My questions to the community:
Is the semantic HTML I have used correct?
There is still a DIV in my Code. What can I use instead of this DIV in the context of semantic HTML?
I have used only Flexbox. Is Grid a better approach? And how should I have used it?
I am very happy about any advice!
