Adding Header to make it more attractive and systematic

[tamanna863]

Without Header everything is looking quite distorted like we have to scroll down again and again to to see the topic . If we add navbar for topics and link for heading it would be much more easier .
We could do this via navbar and anchor tags to to make it feasible . So we don't need to scroll back and forth , we could see the topics by just clicking link

Thanks for raising this issue & giving your bit in this project's development 😇

I don't think this website requires a header bcoz it's a Maths challenge game for kids and there is nothing to add in the header section.

I am closing this issue.
