UI of hero page improved

[amitmishra11]

@mishrashree18 Have a look! I added the Hover effects wherever needed, and changed the font size in the nav as it seemed too small for the nav bar. Also, I changed the layout in the Hero section. As it looked pretty good before also just some things were missing but now I think by making these changes it would look better. Do suggest changes.
