--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');
