#### Explanation
1. `text-shadow: ...` has 4 values with offsets that cover a 4x4 px area to ensure the underline
1. `text-shadow` uses 4 values with offsets that cover a 4x4 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.
2. `background-image: linear-gradient(...)` creates a 90deg gradient with the current
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.
2. `background-image: linear-gradient(...)` creates a 90deg gradient using the
text color (`currentColor`).
3. The `background-*` properties size the gradient as 1x1px at the bottom and repeats it along the x-axis.
4. The `::selection` pseudo selector ensures the text shadow does not interfere with text
3. 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.
4. The `::selection` pseudo selector rule ensures the text shadow does not interfere with text
selection.
#### Browser support
<span class="snippet__support-note">⚠️ The distance of the underline from the text depends on the internal metrics of a font, so you must ensure everyone sees the same font (i.e. no system fonts which will change based on the OS).</span>
