This bookmarklet is designed to assist web developers and SEO specialists in visually identifying content added using the ::before and ::after CSS pseudo-elements. When activated, it applies a semi-transparent red background to the content of these pseudo-elements, highlighting them on the page without altering or duplicating the existing content. This is especially useful in light of Google's recommendation against adding meaningful content or symbols using these pseudo-elements, as such content is not part of the DOM and is ignored by Google Search during indexing.
