Dictionary Web App

The project was very interesting to complete, I tried to make this look exactly like the design as much as I could, but I came up with some questions.

• Should we not show a pause button when a user has started playing an audio for a word ? (Though I've added one to mine, totally with css)
• I used the preferred-color-scheme to automatically set the theme as per system pref, but I found a flash of white screen initially, since retrieving this information takes a liiittllee bit of time. Please let me know if anyone knows a way around this.
