## Description
|
|
<section id='description'>
|
|
Forms commonly use <dfn>checkboxes</dfn> for questions that may have more than one answer.
|
|
Checkboxes are a type of <code>input</code>.
|
|
Each of your checkboxes can be nested within its own <code>label</code> element. By wrapping an <code>input</code> element inside of a <code>label</code> element it will automatically associate the checkbox input with the label element surrounding it.
|
|
All related checkbox inputs should have the same <code>name</code> attribute.
|
|
It is considered best practice to explicitly define the relationship between a checkbox <code>input</code> and its corresponding <code>label</code> by setting the <code>for</code> attribute on the <code>label</code> element to match the <code>id</code> attribute of the associated <code>input</code> element.
|
|
Here's an example of a checkbox:
|
|
<code><label for="loving"><input id="loving" type="checkbox" name="personality"> Loving</label></code>
|
|
</section>
|
|
|
|
## Instructions
|
|
<section id='instructions'>
|
|
Add to your form a set of three checkboxes. Each checkbox should be nested within its own <code>label</code> element. All three should share the <code>name</code> attribute of <code>personality</code>.
|
|
</section>
|
|
|
|
## Tests
|
|
<section id='tests'>
|
|
|
|
```yml
|
|
tests:
|
|
- text: Your page should have three checkbox elements.
|
|
testString: assert($('input[type="checkbox"]').length > 2);
|
|
- text: Each of your three checkbox elements should be nested in its own <code>label</code> element.
|
|
testString: assert($('label > input[type="checkbox"]:only-child').length > 2);
|
|
- text: Make sure each of your <code>label</code> elements has a closing tag.
|
|
testString: assert(code.match(/<\/label>/g) && code.match(/<label/g) && code.match(/<\/label>/g).length === code.match(/<label/g).length);
|
|
- text: Your checkboxes should be given the <code>name</code> attribute of <code>personality</code>.
|
|
testString: assert($('label > input[type="checkbox"]').filter('[name="personality"]').length > 2);
|
|
- text: Each of your checkboxes should be added within the <code>form</code> tag.
|
|
testString: assert($('label').parent().get(0).tagName.match('FORM'));
