Hello @RonakSurana-2001, We appreciate your efforts, but as mentioned in the issue itself, We are not planning to add mobile friendly styles in the project. previously we were redirecting the mobile users to /mobile (issue #48), but since google was identifying all the pages with "page with redirect" (#47) we had to revert that commit (9e48063).

I am sorry but I have to close this PR as not planned. Please refrain from opening PRs without getting assigned to the issue. If you wish to contribute, look for the issues with Available tag and ask to get assigned, I am happy to receive your PR :)
