However, there are a few issues that need to be addressed, such as: - Ensuring the image fills the entire screen. - Maintaining consistent image heights upon resizing.

Is there a way to make the carousel full screen on large screens and ensure that all images have equal width upon resizing without affecting responsiveness?

htmlcssbootstrap-4

Answer №1

Consider adjusting the image height:

style="height: 100vh"

This tweak will ensure the image spans the full screen across various devices

Trust this suggestion proves beneficial!

Answer №2

Instead of placing images within the carousel-item, assign each image as a background of the carousel item div and adjust the background-size property to cover the entire item.

Include the following CSS:

.carousel-item{
  height:100vh;
  background-size:cover !important;
  background-position:center !important;
}
