All solutions

I think there's some problem with github pages because when I'm running my code in browser with editor its working fine, but on github page the buttons move towards bottom.

1. How can I color my image, like in the question?
2. When to use image and background-image, which is suitable for the current situation?
3. How to choose color Palette for the webpage? I'm very bad at it.

Thanks for your suggestions :)
