30秒学会 CSS 片段 – Pretty text underline

A nicer alternative to text-decoration: underline where descenders do not clip the underline.
Natively implemented as text-decoration-skip-ink: auto but it has less control over the underline.

• text-shadow uses 4 values with offsets that cover a 4×4 px area to ensure the underline has a "thick" shadow that covers the line where descenders clip it. Use a color that matches the background. For a larger font, use a larger px size. Additional values can create an even thicker shadow, and subpixel values can also be used.
• background-image: linear-gradient(...) creates a 90deg gradient using the text color (currentColor).
• The background-* properties size the gradient as 100% of the width of the block and 1px in height at the bottom and disables repetition, which creates a 1px underline beneath the text.
• The ::selection pseudo selector rule ensures the text shadow does not interfere with text selection.
