Can CSS `:before` and `:after` Selectors Insert HTML Content?

Inserting HTML with :before and :after CSS Selectors

The question arises whether it is feasible to inject HTML into an element using the CSS selectors :before and :after. Despite knowing the invalidity of the following syntax, a developer seeks clarification for a proper implementation:

li.first div.se_bizImg:before {
    content: "<h1 class="headingDetail">6 Businesses Found <span>(view all)</span></h1>";
}

Understanding the Limitation

Unfortunately, the content property used in :before and :after does not accept HTML; it only handles text. As a result, the proposed method is not applicable.

Alternative Approaches

Two alternative approaches are suggested:

1. JavaScript/jQuery: JavaScript or jQuery provides the flexibility to dynamically insert HTML into an element.
2. Mixing Quotation Marks: In the given code, " is used within a " block, which leads to a syntax error. To resolve this, it is essential to use consistent quotation marks, such as ' within ' or " within ".

Additional Considerations

If the content property did support HTML, it could have led to an infinite loop situation. As content is inserted into content, a potential cycle of insertions would occur, resulting in unexpected behavior.

Conclusion

While the initial approach using CSS selectors is not feasible, alternative solutions such as JavaScript or jQuery offer viable options for inserting HTML into elements. Additionally, proper quotation mark usage is crucial to maintain correct syntax.
