# --description--

O tamanho da fonte é controlado pela propriedade CSS `font-size`, assim:

```css
h1 {
  font-size: 30px;
}
```

# --instructions--

Dentro da tag `<style>` que contém a classe `red-text`, crie um seletor de elementos `p` e defina a propriedade `font-size` com o valor de `16px`.

# --hints--

Entre as tags `style`, defina a propriedade `font-size` com o valor de `16px` no seletor CSS `p` que você criou. O zoom do navegador e do texto devem estar em 100%.

```js
assert(code.match(/p\s*{\s*font-size\s*:\s*16\s*px\s*;\s*}/i));
```
