Why Don't :before and :after Pseudo-elements Work Reliably with Images?

Challenges with Using :before and :after on Images

When attempting to enhance images (img elements) with :before or :after pseudo elements, developers may encounter unexpected behavior. This issue arises due to limitations in the CSS specification.

The CSS specification explicitly states the lack of comprehensive definition for how ::before and ::after interact with replaced elements such as images. This means that the behavior of these pseudo elements with img may vary across browsers.

Is there a Solution?

Currently, there is no reliable method to make pseudo elements fully compatible with images. However, some potential workarounds include:

  • Replace the img element with a background image applied to a div or span element.
  • Use JavaScript to create and manipulate elements that achieve the desired effect.

The future holds the hope of addressing these limitations in the CSS specification, potentially enabling full support for pseudo elements with images. Until then, developers must resort to alternative solutions.
