How do you create an image gallery using only CSS?

To create an image gallery using only CSS, you can use the grid layout to organize images into a structured format. The display: grid property allows you to define rows and columns, while grid-template-columns helps set the layout of the images. By using properties like gap for spacing and object-fit for adjusting image scaling, you can create a visually appealing gallery. Additionally, you can use responsive design techniques, such as auto-fit and minmax, to make the gallery adaptable to different screen sizes without the need for JavaScript.
