Normalmente, tus elementos `button` con las clases `btn` y `btn-default` son tan anchos como el texto que contienen. Por ejemplo:
2021-02-06 04:42:36 +00:00
2021-04-05 15:04:04 +00:00
```html
< button class = "btn btn-default" > Submit< / button >
```
2021-02-06 04:42:36 +00:00
2021-04-05 15:04:04 +00:00
Este botón será tan ancho como la palabra `Submit` .
2021-02-06 04:42:36 +00:00
2021-04-05 15:04:04 +00:00
< button class = 'btn btn-default' > Enviar< / button >
2021-02-06 04:42:36 +00:00
2021-04-05 15:04:04 +00:00
Al hacer los elementos de bloque con la clase `btn-block` , tu botón ocupará el ancho horizontal de la página y cualquier elemento que lo siga se posicionará en una "nueva línea" debajo del bloque.
2021-02-06 04:42:36 +00:00
2021-04-05 15:04:04 +00:00
```html
< button class = "btn btn-default btn-block" > Submit< / button >
```
2021-02-06 04:42:36 +00:00
2021-04-05 15:04:04 +00:00
Este botón tomará el 100% del ancho disponible.
2021-02-06 04:42:36 +00:00
2021-04-05 15:04:04 +00:00
< button class = 'btn btn-default btn-block' > Enviar< / button >
2021-02-06 04:42:36 +00:00
2021-04-05 15:04:04 +00:00
Ten en cuenta que estos botones aún necesitan la clase `btn` .
2021-02-06 04:42:36 +00:00
2021-04-05 15:04:04 +00:00
Añade la clase `btn-block` a tu botón Bootstrap.

Tu botón debe contener las clases `btn` y `btn-default` .
2021-02-06 04:42:36 +00:00
```js
assert($('button').hasClass('btn') & & $('button').hasClass('btn-default'));
```
2021-04-05 15:04:04 +00:00
Tu botón debe contener la clase `btn-block` .
2021-02-06 04:42:36 +00:00
```js
assert($('button').hasClass('btn-block'));
```
2021-04-05 15:04:04 +00:00
Todos tu elementos `button` deben tener etiquetas de cierre.
2021-02-06 04:42:36 +00:00
```js
assert(
code.match(/< \/button > /g) &&
code.match(/< button / g ) & &
code.match(/< \/button > /g).length === code.match(/< button / g ). length
);
```
