// Tests for `min-height` property in CSS
// Based on CSS Box Sizing Module Level 3:
// - min-height sets the minimum height constraint
// - If content/height is less than min-height, the element expands
// - min-height takes precedence over max-height

use crate::*;

// Case: min-height with no explicit height
// Spec points:
// - min-height ensures element is at least the specified height
// In this test:
// - Element: min-height=100px, no height specified
// - Expected: height=100px (expanded to min)
#[test]
