如何在鼠标悬停的两个图像之间滑动？

How can I create a section contaiinng 2 images side by side which will expand one of the images to full width when hovering over it. i.e when I hover over the left hand side image the image will expand to the right to display the full image and cover the image that was on the right hand side. Then when I hover over the right hand side image that will expand to the left and cover the left side image.How can I create a section contaiinng 2 images
