Used Prompt to generate this site:

Write an HTML, CSS, and JS code at once. and design and develop a typing game. for mobile and desktop both. designs should be modern and have the most animations. in this have browser storage to save Best Scores. If a user loads my website then the user has to press the Start game button to start the game. and there will be a restart button also. restart button will appear only when the game is running. and if the user types then the input field's border blinks for 1-sec green when the user enters the right letter of the word and the border will blink red if the user enters the wrong letter. The user will get notified when the game time ends. and a pop-up will show its game result and have a close button to close the pop-up. and then the user can restart the game. theme should be white and have a modern design. in the game, there is a 30-second timer. if the timer ends game is over. there should be a dark mode toggle button. In the website game, there should be a Score. when a player is playing the game player can see its real-time score at the top. make the design more modern and add some shapes to make it attractive.

I added more words externally and placed the 'Best Score' text at the top of the game window.
