The css file in the head tag can set the height of the image in the body tag

Question

Set the width and height of the css file in the head tag. Why do you set the width and height of the img in the body tag?

If you want the images in the entire body to have the same height, then the code should be

img{
    height:100px;
}

If it is a picture under a certain element, the code should be

    height:100px;
}
