@harsh72835 there have been changes in the master branch, please pull the latest changes and update accordingly.
Also use a shade of yellow/orange instead of purple for button border

[harsh72835]

we can change the font color right?

[manankohlii]

@harsh72835 if it goes with the colour scheme of the website, sure.

Okay

Unnecessary CSS lines can be removed altogether to avoid cluttering the code base for other contributors.

[akashchouhan16]

Remove unused text-shadow property.

You must be using some code formatting tool and hence even for a minor CSS btn adjustment, multiple lines have been modified. For future PRs, you can try and avoid unnecessary code changes, otherwise, the PR is great. :)
