Can you determine the height of an image if only the width and border width are provided?

Currently delving into the world of HTML and CSS, I've successfully configured the img element's width and border width using a style element.

However, one aspect that is still puzzling me is how the height is calculated in this scenario. I've tried searching through W3School documentation for an explanation without much success.

Answer №1

An image is considered a replaced inline element and always has an intrinsic ratio, so the following rule applies:

If 'height' is set to 'auto' and the element has an intrinsic ratio, then the used value of 'height' will be:

(used width) / (intrinsic ratio)
