Excluding Emojis From Transparent Text Clipping

This CSS trick creates a neat hover effect on links by applying a linear gradient background, clipping it to the text, and making the text transparent. However, this unexpectedly affects emojis, making them transparent as well. While this is technically correct (emojis are glyphs), it's not always desirable.

The article explores solutions. The CSS font-variation-emoji and font-palette properties, while proposed in the CSS Fonts Module Level 4, aren't currently suitable for this specific problem. A pure CSS solution seems unavailable.

The author suggests two workarounds:

1. JavaScript: Large platforms like WordPress and Twitter use image-based emojis (often SVGs). Replacing text-based emojis with images would prevent the transparency effect. This requires custom JavaScript to detect and replace emojis.

2. Positioning: The simplest solution is to place the emoji outside the <a></a> link tag. This prevents the CSS from affecting it. However, this is only practical if the emoji is consistently positioned at the beginning or end of the link text; mid-link emojis present a challenge.

The article concludes that while a simple CSS solution is lacking, the need for control over emoji styling in such scenarios highlights a potential area for future CSS development. The image below illustrates the issue:
