# --description--
|
|
|
|
Normalmente, i tuoi elementi `button` con le classi `btn` e `btn-default` sono larghi solo quanto il testo che contengono. Per esempio:
|
|
|
|
```html
|
|
<button class="btn btn-default">Submit</button>
|
|
```
|
|
|
|
Questo pulsante sarà ampio solo quanto la parola `Submit`.
|
|
|
|
<button class='btn btn-default'>Submit</button>
|
|
|
|
Rendendolo elemento di blocco con la classe aggiuntiva `btn-block`, il tuo pulsante si estenderà per riempire l'intero spazio orizzontale della tua pagina e tutti gli elementi che seguiranno scorreranno su una "nuova linea" sotto il blocco.
|
|
|
|
```html
|
|
<button class="btn btn-default btn-block">Submit</button>
|
|
```
|
|
|
|
Questo pulsante prenderà il 100% della larghezza disponibile.
|
|
|
|
<button class='btn btn-default btn-block'>Submit</button>
|
|
|
|
Nota che questi bottoni hanno ancora bisogno della classe `btn`.
|
|
|
|
Aggiungi la classe `btn-block` di Bootstrap al tuo pulsante.
|
|
|
|
# --hints--
|
|
|
|
Il tuo pulsante dovrebbe avere ancora le classi `btn` e `btn-default`.
|
|
|
|
```js
|
|
assert($('button').hasClass('btn') && $('button').hasClass('btn-default'));
|
|
```
|
|
|
|
Il tuo pulsante dovrebbe avere la classe `btn-block`.
|
|
|
|
```js
|
|
assert($('button').hasClass('btn-block'));
|
|
```
|
|
|
|
Tutti i tuoi elementi `button` dovrebbero avere dei tag di chiusura.
|
|
|
|
```js
|
|
assert(
|
|
code.match(/<\/button>/g) &&
|
|
code.match(/<button/g) &&
|
|
code.match(/<\/button>/g).length === code.match(/<button/g).length
|
|
);
|
|
```
