# --description--
|
|
|
|
La direttiva `@for` aggiunge stili in un ciclo, in modo molto simile a un ciclo `for` di JavaScript.
|
|
|
|
`@for` è usato in due modi: "start through end" o "start to end". La differenza principale è che "start **to** end" *esclude* il numero finale dal conteggio, mentre "start **through** end" *include* il numero finale nel conteggio.
|
|
|
|
Ecco un esempio di start **through** end:
|
|
|
|
```scss
|
|
@for $i from 1 through 12 {
|
|
.col-#{$i} { width: 100%/12 * $i; }
|
|
}
|
|
```
|
|
|
|
La parte `#{$i}` è la sintassi che combina una variabile (`i`) con il testo per formare una stringa. Quando il file Sass viene convertito in CSS, appare così:
|
|
|
|
```scss
|
|
.col-1 {
|
|
width: 8.33333%;
|
|
}
|
|
|
|
.col-2 {
|
|
width: 16.66667%;
|
|
}
|
|
|
|
...
|
|
|
|
.col-12 {
|
|
width: 100%;
|
|
}
|
|
```
|
|
|
|
Questo è un modo potente per creare un layout griglia. Ora hai dodici opzioni per le larghezze delle colonne disponibili come classi CSS.
|
|
|
|
# --instructions--
|
|
|
|
Scrivi una direttiva `@for` che usa una variabile `$j` che va da 1 **a** 6.
|
|
|
|
Dovrebbe creare 5 classi chiamate da `.text-1` a `.text-5` dove ognuna ha una `font-size` impostata a 15px moltiplicata per l'indice.
|
|
|
|
# --hints--
|
|
|
|
Il tuo codice dovrebbe utilizzare la direttiva `@for`.
|
|
|
|
```js
|
|
assert(code.match(/@for /g));
|
|
```
|
|
|
|
La tua classe `.text-1` dovrebbe avere un `font-size` di 15px.
|
|
|
|
```js
|
|
assert($('.text-1').css('font-size') == '15px');
|
|
```
|
|
|
|
La tua classe `.text-2` dovrebbe avere un `font-size` di 30px.
|
|
|
|
```js
|
|
assert($('.text-2').css('font-size') == '30px');
|
|
```
|
|
|
|
La tua classe `.text-3` dovrebbe avere un `font-size` di 45px.
|
|
|
|
```js
|
|
assert($('.text-3').css('font-size') == '45px');
|
|
```
|
|
|
|
La tua classe `.text-4` dovrebbe avere un `font-size` di 60px.
|
|
|
|
```js
|
|
assert($('.text-4').css('font-size') == '60px');
|
|
```
|
|
|
|
La tua classe `.text-5` dovrebbe avere un `font-size` di 75px.
|
|
|
|
```js
|
|
assert($('.text-5').css('font-size') == '75px');
|
|
```
