Html - Display div on hover and make it scrollable

To display a <div> on hover and make it scrollable in HTML and CSS, you can achieve this by using CSS for the hover effect and applying styles to make the <div> scrollable when its content exceeds its size. Here's how you can do it:

HTML Structure

Assume you have a <div> that you want to display on hover, and you want it to be scrollable if its content overflows. Here's a basic structure:

<div class="parent"> <div class="hover-div"> <p>This is some content inside the scrollable div.</p> <p>Another line of content to demonstrate scrolling.</p> <p>More lines of content to make the div scrollable.</p> </div> </div>

CSS Styling

  1. Initially Hide the Div: Set the .hover-div to be hidden by default and only display when its parent .parent is hovered over.

  2. Scrollable Content: Apply styles to .hover-div to make it scrollable if its content exceeds its dimensions.

Here's the CSS:

.parent { position: relative; width: 300px; /* Adjust width as needed */ height: 200px; /* Adjust height as needed */ background-color: #f0f0f0; overflow: hidden; /* Hide overflow content */ border: 1px solid #ccc; } .hover-div { position: absolute; top: 0; left: 100%; /* Position it next to the parent */ width: 100%; max-height: 100%; /* Ensure it doesn't exceed parent's height */ padding: 10px; background-color: #fff; border: 1px solid #ccc; box-shadow: 0 0 5px rgba(0, 0, 0, 0.1); overflow-y: auto; /* Enable vertical scrolling */ display: none; /* Initially hide the div */ } .parent:hover .hover-div { display: block; /* Display the div on hover */ }

Explanation:

  • .parent: This is the container <div> that contains .hover-div. It has overflow: hidden to hide any overflow from .hover-div.

  • .hover-div: This <div> is positioned absolutely relative to its parent .parent. It is initially hidden (display: none) and displayed (display: block) only when .parent is hovered over.

  • Scrollable Content: overflow-y: auto enables vertical scrolling when the content exceeds the height of .hover-div.

  • Hover Effect: .parent:hover .hover-div ensures that .hover-div is displayed when .parent is hovered over.

Adjustments:

  • Customize Dimensions: Adjust the width, height, and max-height properties of .parent and .hover-div to fit your design requirements.

  • Styling: Modify the background colors, borders, padding, and box shadow to match your design preferences.

This setup allows you to create a hover effect where a <div> becomes visible and scrollable when its parent is hovered over, providing a user-friendly interface for displaying additional content or menus.
