A children's crossword puzzle displays an 11-by-11 grid of letter cells with across and down clues listed alongside. The game uses plain JavaScript and the Document Object Model (DOM) to render the interactive grid, manage user input, and highlight words. Clicking a clue highlights the corresponding word in the grid, while the "Check Answers" and "Show Solution" buttons compare user entries against the embedded word list. The interface relies on CSS grid for layout and event listeners for navigation and validation.
