## CSS Gotchas
### Negating CSS Functions
**WRONG — silently ignored by browsers (no console error):**
```css
right: -clamp(28px, 3.5vw, 44px); /* Browser ignores this */
margin-left: -min(10vw, 100px); /* Browser ignores this */
```
**CORRECT — wrap in `calc()`:**
```css
right: calc(-1 * clamp(28px, 3.5vw, 44px)); /* Works */
margin-left: calc(-1 * min(10vw, 100px)); /* Works */
```
CSS does not allow a leading `-` before function names. The browser silently discards the entire declaration — no error, the element just appears in the wrong position. **Always use `calc(-1 * ...)` to negate CSS function values.**
