What methods could a web crawler use to access and analyze the content within ::before?

In the world of web development, a pseudo element like ::before or ::after may seem invisible in the DOM tree. It's a tricky situation because you can't just target it using a selector.

So, how do you retrieve the content within a pseudo element? Let's consider this scenario:

<div>This is <span></span>n apple.</div>
...
span::before {
    content : "a"
}

Result: This is an apple.

If you try to extract the text from the div, you'll only capture This is n apple. without the added content from span::before.

What's the best way to tackle this challenge?

Answer №1

What is the best approach to handle this issue?

Truthfully, it's advisable to avoid utilizing pseudo-elements for solving this problem.

Pseudo-elements are specifically intended for displaying content outside of the document structure.

This "generated content", defined by the content property of the ::before and ::after pseudo-elements, is usually used for decorative purposes only.

As a result, there is no need for search engines to index generated content.
