// Tests for `max-height` property in CSS
// Based on CSS Box Sizing Module Level 3:
// - max-height sets the maximum height constraint
// - If content/height exceeds max-height, the element is clamped
// - max-height takes precedence over height but min-height takes precedence over max-height

use crate::*;

// Case: max-height greater than height (no clamping)
// Spec points:
// - When max-height > height, max-height has no effect
// In this test:
// - Element: max-height=100px, height=50px
// - Expected: height=50px (not clamped)
#[test]
