Hello @TimidRobot , @Shafiya-Heena, I would love your review on this PR. Thank you for your time

Hi, and thank you for doing this work. After further review the Issue in question here as moved to 🚧 status: blocked Blocked & therefore, not ready for work so I'm closing this PR for now.

Additionally, this PR contains changes to vocabulary.css directly which should be avoided. Localized changes should be bound outside of Vocabulary (such as within the style.css file)

Hi @adebisi4145 , great work you did here.
@possumbilities , thank you for the last line. I usually make the mistake of making changes to the vocbulary.css.

Bisi, might I also add that for mobile screens, a hover effect is not needed as the user will not be hovering over the button but rather tapping on it. A hover effect is usually applied and greatly advised to be applied to desktop screens only.
