# --description--

When HTML elements are placed one level below another they are called <dfn>children</dfn> of that element. For example, the button elements in this challenge with the text "#target1", "#target2", and "#target3" are all children of the `<div class="well" id="left-well">` element.

jQuery has a function called `children()` that allows you to access the children of whichever element you've selected.

Here's an example of how you would use the `children()` function to give the children of your `left-well` element the color `blue`:

`$("#left-well").children().css("color", "blue")`

# --instructions--

Give all the children of your `right-well` element the color orange.

# --hints--

All children of `#right-well` should have orange text.

```js
assert($('#right-well').children().css('color') === 'rgb(255, 165, 0)');
```

You should use the `children()` function to modify these elements.

```js
assert(code.match(/\.children\(\)\.css/g));
```

You should only use jQuery to add these classes to the element.

```js
assert(code.match(/<div class="well" id="right-well">/g));
```
