 In this example, we have a `div` element with class named `box`. This element will be occupying `100px` in height and width, whereas the background color will be `skyblue`.
 
 Pixels are a fixed-size unit of measurement in CSS, providing precise control over dimensions.

 The above example demonstrates how `min-width` and `min-height` work.
 
 Even though the box has its `width` and `height` set to 50px, it will actually be `100px` by `100px`. This is because the `min-width` and `min-height` are set to `100px`, which are larger than the specified `width` and `height`.

 The above example demonstrates how `max-width` and `max-height` override `width` and `height`. Even though the box is set to `200px` by `200px`, it will actually be `150px` by `150px`. This is because the `max-width` and `max-height` are set to `150px`, which is smaller.
 
 Remember, when `max-width` or `max-height` are smaller than `width` or `height`, they take precedence. This is important for controlling the maximum size of elements in your layouts.
