Question

Sunsets and night comes .

Answer 1

You can't do graphics with C++ (at least not on SoloLearn) except maybe some ascii art (character drawings).
You should look into HTML/CSS courses if you are interested in web design.
Maybe this will give you an idea, this youtube channel is done by one of the top SoloLearners

Answer 2

If you are asking for the ability to do this off of SoloLearn, you should look into graphics libraries.
2D : SDL2
3D: Unreal Engine, OpenGL
