# --description--
You can use radio buttons for questions where you want only one answer out of multiple options.
Here is an example of a radio button with the option of `cat`: ` cat`. Remember that `input` elements are self-closing.
Before the text input, add a radio button with the option `Indoor`.
# --hints--
You should create an input element for your radio button. Check the syntax.
```js
assert($('form > input').length >= 2);
```
Your `input` element should have an opening tag, but not a closing tag.
```js
assert($('form > input') && !code.match(/<\/input\>/g));
```
You should only have added one input element for your radio button. Remove any extras.
```js
assert($('form > input').length === 2);
```
Your new `input` element should be above the existing `input` with `type` attribute set to `text`. You have them in the wrong order.
```js
const existingInputElem = document.querySelector('form > input[type="text"]');
assert(
existingInputElem &&
existingInputElem.previousElementSibling.nodeName === 'INPUT'
);
```
Your new `input` element does not have a `type` attribute. Check that there is a space after the opening tag's name.
```js
assert($('input')[0].hasAttribute('type'));
```
Your new `input` element should have a `type` attribute with the value `radio`. You have either omitted the value or have a typo. Remember that attribute values should be surrounded with quotation marks.
```js
assert(
$('input')[0]
.getAttribute('type')
.match(/^radio$/i)
);
```
Although you have set the new `input` element's `type` attribute to `radio`, it is recommended to always surround the value of an attribute with quotation marks.
```js
assert(!/\<\s*input\s+type\s*=\s*radio/i.test(code));
```
The `radio` button's ` Indoor` text should be located after it instead of before it.
```js
const radioInputElem = $('input')[0];
assert(!radioInputElem.previousSibling.nodeValue.match(/Indoor/i));
```
The text ` Indoor` should be located directly to the right of your `radio` button. Make sure there is a space between the element and the text. You have either omitted the text or have a typo.
```js
const radioInputElem = $('input')[0];
assert(
radioInputElem.nextSibling.nodeValue.replace(/\s+/g, ' ').match(/ Indoor/i)
);
```
