All solutions

I am not sure about my JS code. The arrows from the features and company links change using JavaScript. I don't know if this was the proper way to do it. Also, I would appreciate if someone told me how to add animations for the dropdown menu and mobile menu.

Centering the card vertically was difficult at first but after some research I was able to do it. Have in mind that I am a newbie haha!

I tried to use BEM for my CSS classes but I'm sure I did it wrong. Would you please give me some feedback on how to use BEM for my classes?

Thanks in advance, Edgar.
