Setting the object fit value to cover is like setting the background size to cover for the background image.

Now, we will be inserting the grid items inside the grid container: 8x8 CSS Grid (8 Column Tracks & 8 Row Tracks) with Grid Lines from 1 to 9 (Both Columns & Rows) Note: All direct children of grid automatically become grid items. We are doing this by setting the height of the row to 5vw (viewport width). I experimented with these heights and came to the conclusion that 5% of viewport width is the perfect size for the height. We have 8 rows each with the height of 5 viewport width. } Note: The height of the rows is tied to the viewport width, so that the cells maintain its aspect ratio perfectly fine. In our example, I have given the value of 15px to make our grid look better. The value for grid gap can be any CSS length unit. grid-gap: It defines the size of the gap between rows and columns in a grid layout.In our example, we will we be making an 8x8 grid container. We declare these properties on the grid container. We use the grid-template-columns property to set the column tracks and grid-template-rows to set the row tracks.So, the div, with the class grid is going to be our grid container. A grid container is defined by setting an element’s display property to the grid.We can create a grid of other sizes also but that depends on the type of gallery you want. For example: Above is a gallery of images with images of varying width and height which is a perfect use case for CSS grids. You can achieve the same functionality very quickly using CSS Grids.

Image galleries made by websites like Unsplash, Pinterest Etc, are made by techniques like positioning or translating the image item which is a very cumbersome task to do.
