# width property Null safety

num width
override

The width of this rectangle.

This is equivalent to the `width` function in jQuery and the calculated `width` CSS value, converted to a dimensionless num in pixels. Unlike `getBoundingClientRect`, `width` will return the same numerical width if the element is hidden or not.

## Implementation

    num get width;

void width= (dynamic newWidth)

Set the current computed width in pixels of this element.

newWidth can be either a num representing the width in pixels or a Dimension object. This is equivalent to the `width` function in jQuery and the calculated `width` CSS value, converted to a dimensionless num in pixels.

Note that only the content width can be set via this method.

## Implementation

    set width(dynamic newWidth) {
      throw new UnsupportedError("Can only set width for content rect.");
    }
