Was built by flex, personal framework, some additions

Hey buds, sup? <: I want your views about the design, I've completed the challenge but with some additions, so give me your opinion about it, I used also personal framework that I used in building a website, I know it's wrong to use it because it's full of things that I don't need here in this design, but It's okay I guess it's just a challenge so yeah great. I'm waiting any feedback from you guys so please see the code and tell me your point of view, we learn from our mistakes.❤
