@ramirocruz07 The indentation does not seem to be right here, you should use prettier for code formatting 🙌

[Murdock9803]

Are the changes in Gemfile.lock necessary ? As this is a PR about design, It would be better to restrict the changes to files concerned about that 🙌

[Murdock9803]

similarly, the Gemfile should also not be changed

[Murdock9803]

These blank lines are not needed here, you can format the code with prettier code formatted to avoid these mistakes. there are more formatting issues like in line 82, line 85, etc..

I am not sure whether the change was needed or not, as we rely on vocabulary for the design scheme of the site. But if its needed, I have left some review comment here 🙌
