# --description--

È possibile utilizzare gli intervalli (span) per creare degli elementi in linea. Ricordi quando abbiamo usato la classe `btn-block` per fare in modo che il bottone riempisse l'intera riga?

<button class='btn' style='background-color: rgb(0, 100, 0);  color: rgb(255, 255, 255);'>bottone normale</button>

<button class='btn btn-block' style='background-color: rgb(0, 100, 0);  color: rgb(255, 255, 255);'>bottone btn-block</button>

Questo mostra la differenza tra un elemento "inline" e un elemento "block".

Utilizzando l'elemento inline `span`, puoi inserire diversi elementi sulla stessa linea, e anche stilizzare diverse parti della stessa linea in modo diverso.

Usando un elemento `span`, annida la parola `love` all'interno dell'elemento `p` che al momento ha il testo `Things cats love`. Quindi dai allo `span` la classe `text-danger` per rendere il testo rosso.

Ecco come faresti questo per l'elemento `p` che ha il testo `Top 3 things cats hate`:

```html
<p>Top 3 things cats <span class="text-danger">hate:</span></p>
```

# --hints--

Il tuo elemento `span` dovrebbe essere all'interno dell'elemento `p`.

```js
assert($('p span') && $('p span').length > 0);
```

Il tuo elemento `span` dovrebbe avere solo il testo `love`.

```js
assert(
  $('p span') &&
    $('p span').text().match(/love/i) &&
    !$('p span')
      .text()
      .match(/Things cats/i)
);
```

Il tuo elemento `span` dovrebbe essere di classe `text-danger`.

```js
assert($('span').hasClass('text-danger'));
```

Il tuo elemento `span` dovrebbe avere un tag di chiusura.

```js
assert(
  code.match(/<\/span>/g) &&
    code.match(/<span/g) &&
    code.match(/<\/span>/g).length === code.match(/<span/g).length
);
```
