# Responsive Arrays
All CSS properties accept arrays as values for responsive styles.
<div
css={css({
fontSize: [ 4, 5, 6 ],
})}
/>
In this example, fontSize accepts an array, picking up values from the theme.fontSizes scale, and borderBottom is passed through as plain CSS.
<div
css={css({
// Styled System key
fontSize: [ 3, 4, 5 ],
// CSS property
borderBottom: '2px solid tomato',
})}
/>
