A common scenario is wanting to display a button when hovering over a card component. In this post, we'll explore how to achieve this effect specifically for an Angular Material card containing an 'x' button that should only appear on hover. The Problem You have an Angular Material card with a title, content, and an 'x' button (close button) typically used to dismiss or close the card. However, you want this 'x' button to be hidden when the card is not being hovered over, and only shown when the user hovers their mouse over the card itself. Your initial thought was to utilize the ngClass directive, but you were unsure how to track whether the user was hovering over the card. The Solution To implement the hover effect, we can utilize Angular's event binding capabilities. Here's how you can do this step-by-step: Step 1: Modify Your HTML Code You'll need to add mouse event handlers to your <mat-card> to toggle the visibility of the button. Here’s an example of how you can set it up: [[See Video to Reveal this Text or Code Snippet]] Step 2: Declare the Variable in the TypeScript File In your component's TypeScript file, you need to declare a boolean variable showButton. This variable will dictate whether the 'x' button is visible or not based on hover actions.

This approach can enhance user experience by providing interactive feedback when the user is navigating through your application. Feel free to apply this concept in your own Angular projects to add dynamic behavior to your components. Happy coding!
