# --description--

CSS tiene una propiedad llamada `width` que controla el ancho de un elemento. Al igual que con las fuentes, usaremos la unidad de medida `px` (píxeles) para especificar el ancho de la imagen.

Por ejemplo, si queremos crear una clase CSS llamada `larger-image` que le asigne a los elementos HTML un ancho de 500 píxeles, usamos el siguiente código:

```html
<style>
  .larger-image {
    width: 500px;
  }
</style>
```

# --instructions--

Crea una clase llamada `smaller-image` y úsala para redimensionar la imagen de modo que solo tenga 100 píxeles de ancho.

# --hints--

Tu elemento `img` debe incluir la "class" `smaller-image`.

```js
assert(
  $("img[src='https://cdn.freecodecamp.org/curriculum/cat-photo-app/relaxing-cat.jpg']").attr('class')
    .trim().split(/\s+/g).includes('smaller-image')
);
```

Tu imagen debe tener 100 píxeles de ancho.

```js
assert(
  $('img').width() < 200 &&
    code.match(/\.smaller-image\s*{\s*width\s*:\s*100px\s*(;\s*}|})/i)
);
```
