An image gallery is like a digital album where we can put our multiple images to attract user attention. We have used Bootstrap a CSS framework for Creating a Responsive Image Gallery where the layout adjusts automatically based on the screen size, ensuring that it looks good on both large desktop screens and smaller mobile devices.
Responsive Image Gallery in Bootstrap
- First, create a basic HTML structure and provide a background color using the "bg-success" class.
- After that create a container using a "container" class which holds the entire gallery.
- Use Bootstrap's utility classes for layout and positioning, such as "position-relative", "top-50", "start-50", and "translate-middle", to center the captions within the images.
- Also, use JavaScript to toggle the visibility of the captions on hover.
