# --description--
|
|
|
|
Cuando los elementos HTML se colocan un nivel por debajo de otro, se denominan <dfn>hijos</dfn> de ese elemento. Por ejemplo, los elementos botón en este desafío con el texto `#target1`, `#target2`, y `#target3` son todos hijos del elemento `<div class="well" id="left-well">`.
|
|
|
|
jQuery tiene una función llamada `children()` que te permite acceder a los hijos del elemento que hayas seleccionado.
|
|
|
|
Aquí hay un ejemplo de cómo usarías la función `children()` para dar a los hijos de tu elemento `left-well` el color `blue`:
|
|
|
|
```js
|
|
$("#left-well").children().css("color", "blue")
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Dale a todos los hijos de tu elemento `right-well` el color naranja.
|
|
|
|
# --hints--
|
|
|
|
Todos los hijos de `#right-well` deben tener texto naranja.
|
|
|
|
```js
|
|
assert($('#right-well').children().css('color') === 'rgb(255, 165, 0)');
|
|
```
|
|
|
|
Debes usar la función `children()` para modificar estos elementos.
|
|
|
|
```js
|
|
assert(code.match(/\.children\(\)\.css/g));
|
|
```
|
|
|
|
Solo debes usar jQuery para agregar estas clases al elemento.
|
|
|
|
```js
|
|
assert(code.match(/<div class="well" id="right-well">/g));
|
|
```
