## Description
|
|
<section id='description'>
|
|
D3 lets you add inline CSS styles on dynamic elements with the <code>style()</code> method.
|
|
The <code>style()</code> method takes a comma-separated key-value pair as an argument. Here's an example to set the selection's text color to blue:
|
|
<code>selection.style("color","blue");</code>
|
|

|
|
|
|
## Instructions
|
|
<section id='instructions'>
|
|
Add the <code>style()</code> method to the code in the editor to make all the displayed text have a <code>font-family</code> of <code>verdana</code>.
|
|
</section>
|
|
|
|
## Tests
|
|
<section id='tests'>
|
|
|
|
```yml
|
|
tests:
|
|
- text: Your <code>h2</code> elements should have a <code>font-family</code> of verdana.
|
|
testString: assert($('h2').css('font-family') == 'verdana');
|
|
- text: Your code should use the <code>style()</code> method.
|
|
testString: assert(code.match(/\.style/g));
|
|
|
|
```
