This question explores CSS and addresses practical considerations related to: How can I create a smooth fade-in effect for images using CSS?

To create a smooth fade-in effect for images using CSS, you can utilize the `opacity` property along with CSS transitions. This allows the image to gradually appear on the page. .fade-in-image { opacity: 0; transition: opacity 2s ease-in-out; } .fade-in-image.visible { opacity: 1; } window.onload = function() { document.getElementById('image').classList.add('visible'); }; ADDITIONAL COMMENT: The `.fade-in-image` class sets the initial opacity to 0, making the image invisible. The `transition` property specifies the duration and timing function for the opacity change. JavaScript is used to add the `visible` class after the page loads, triggering the fade-in effect. Adjust the transition duration (`2s` in this example) to make the fade-in faster or slower. ✅
