## Description
|
|
<section id='description'>
|
|
When a form gets submitted, the data is sent to the server and includes entries for the options selected. Inputs of type <code>radio</code> and <code>checkbox</code> report their values from the <code>value</code> attribute.
|
|
|
|
For example:
|
|
|
|
```html
|
|
<label for="indoor">
|
|
<input id="indoor" value="indoor" type="radio" name="indoor-outdoor">Indoor
|
|
</label>
|
|
<label for="outdoor">
|
|
<input id="outdoor" value="outdoor" type="radio" name="indoor-outdoor">Outdoor
|
|
</label>
|
|
```
|
|
|
|
|
|
Here, you have two <code>radio</code> inputs. When the user submits the form with the <code>indoor</code> option selected, the form data will include the line: <code>indoor-outdoor=indoor</code>. This is from the <code>name</code> and <code>value</code> attributes of the "indoor" input.
|
|
|
|
If you omit the <code>value</code> attribute, the submitted form data uses the default value, which is <code>on</code>. In this scenario, if the user clicked the "indoor" option and submitted the form, the resulting form data would be <code>indoor-outdoor=on</code>, which is not useful. So the <code>value</code> attribute needs to be set to something to identify the option.

|
## Instructions
|
|
<section id='instructions'>
|
|
Give each of the <code>radio</code> and <code>checkbox</code> inputs the <code>value</code> attribute. Use the input label text, in lowercase, as the value for the attribute.
