Answer 1

Kh Sayeed hi,
Code review by peers is good and
if you'd like to know another way (a complementary one) to check if something is wrong you can use the w3 validator that check if your html or CSS respond to the standard.
You can check here:

Answer 2

That depends from you, if you got that, what you expected.
