I would also like to recommend that we should remove the about section of the readme as the information about the website is already provided below the main heading.

The latest commit removes the additional underline when you hover over a link

Thanks @SrNightmare09 for contributing but please make one change per PR, otherwise I will have to merge the entire PR. I can't merge this since the underline in the "GitHub" text is intentional. Can you make another PR making change in just docs.

@SrNightmare09 The best way to get PRs merged is to make small PRs with small changes so that I can roll back rather than 1 big PR with 5-6 commits. Also do one thing in one PR. If PR is about docs only do docs. For any other additions, you can open another PR.

@1Shubham7 I have made the changes and reverted to only change in documentation.

@SrNightmare09 I told you the underline looks good. It is intentional. Please make PR for the other commits where you change the readme doc.

I have removed the changes to the css files, so the underline is still visible. I don't seem to understand what else you want from me.

@SrNightmare09 Its perfect now!! I am really sorry if this was annoying but mostly in open-source one should only do in the PR what he/she was assigned in the issue and make small PRs.
