To create a confirmation dialog component, you'll need to build a modal that appears when the delete button is clicked. Here's how to implement it: 1. First, add this HTML structure for the confirmation dialog in your HTML file: ```html

Confirm Delete

Are you sure you want to delete this task?

``` 2. Add the CSS styles for the dialog: ```css .confirmation-dialog { display: none; position: fixed; top: 0; left: 0; width: 100%; height: 100%; background-color: rgba(0, 0, 0, 0.5); justify-content: center; align-items: center; } .dialog-box { background-color: white; padding: 20px; border-radius: 8px; box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1); text-align: center; } .dialog-buttons { margin-top: 15px; display: flex; justify-content: center; gap: 10px; } .confirm-btn, .cancel-btn { padding: 8px 16px; border: none; border-radius: 4px; cursor: pointer; font-weight: 500; } .confirm-btn { background-color: #4CAF50; color: white; } .cancel-btn { background-color: #f44336; color: white; } ``` 3. Add the JavaScript to handle the dialog: ```javascript function showDialog() { document.querySelector('.confirmation-dialog').style.display = 'flex'; } function hideDialog() { document.querySelector('.confirmation-dialog').style.display = 'none'; } // Add event listeners document.querySelector('.cancel-btn').addEventListener('click', hideDialog); document.querySelector('.confirm-btn').addEventListener('click', function() { // Here you'll implement the actual deletion logic hideDialog(); }); ``` This implementation creates a centered modal dialog with a semi-transparent background. The dialog has two buttons: "Confirm" and "Cancel". When the user clicks "Confirm", you can implement the deletion logic, and when they click "Cancel", the dialog closes. Next steps: 1. Connect this dialog to your delete button click event listener 2. Implement the actual task deletion logic in the confirm button handler 3. Add animation for the dialog appearance/disappearance To learn more about these concepts: - [CSS Modals](https://www.w3schools.com/howto/howto_css_modals.asp) - [Flexbox Layout](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flexible_Box_Layout/Basic_Concepts_of_Flexbox) - [Event Delegation](https://javascript.info/event-delegation)
