```javascript
function updateGradientPreview() {
    const type = gradientType.value;
    const start = gradientStart.value;

    } else {
        preview.style.background = `radial-gradient(circle, ${start}, ${end})`;
    }
}
```

### 3. Spacing Live Preview

function updatePreview() {
    previewSection.style.paddingTop = sectionPaddingTop.value + 'px';
