--description--

D3 methods can add styles to the bar labels. The fill attribute sets the color of the text for a text node. The style() method sets CSS rules for other styles, such as font-family or font-size.

--instructions--

Set the font-size of the text elements to 25px, and the color of the text to red.

--hints--

The labels should all have a fill color of red.

assert($('text').css('fill') == 'rgb(255, 0, 0)');

The labels should all have a font-size of 25 pixels.

assert($('text').css('font-size') == '25px');
