Hi there @keshavgoyal2014! I can’t really see your code to comment on it, as you pasted it directly into the discourse post, and it just ran the code instead of showing it 
Best thing to do in the future is to either host your code on an external site like github, codepen or thimble, or to paste it in between two sets of three backticks (e.g. ```). If you do that, it will print your actual code as is, rather than running it.
In any case, well done for trying the example. You can find solutions, marking guides, etc. at our main discourse forum for this assessment — see "Structuring a page of content" assessment
