# --description--
|
|
|
|
I bordi CSS hanno proprietà come `style`, `color` e `width`.
|
|
|
|
Per esempio, se volessimo creare un bordo rosso di 5 pixel attorno ad un elemento HTML, potremmo usare questa classe:
|
|
|
|
```html
|
|
<style>
|
|
.thin-red-border {
|
|
border-color: red;
|
|
border-width: 5px;
|
|
border-style: solid;
|
|
}
|
|
</style>
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Crea una classe chiamata `thick-green-border`. Questa classe dovrebbe aggiungere un bordo di 10px, solido e verde intorno ad un elemento HTML. Applica la classe alla foto del gatto.
|
|
|
|
Ricorda che puoi applicare più classi a un elemento usando il suo attributo `class`, separando ogni nome di classe con uno spazio. Per esempio:
|
|
|
|
```html
|
|
<img class="class1 class2">
|
|
```
|
|
|
|
# --hints--
|
|
|
|
Il tuo elemento `img` dovrebbe avere la classe `smaller-image`.
|
|
|
|
```js
|
|
assert($('img').hasClass('smaller-image'));
|
|
```
|
|
|
|
Il tuo elemento `img` dovrebbe avere la classe `thick-green-border`.
|
|
|
|
```js
|
|
assert($('img').hasClass('thick-green-border'));
|
|
```
|
|
|
|
La tua immagine dovrebbe avere uno spessore del bordo di `10px`.
|
|
|
|
```js
|
|
assert(
|
|
$('img').hasClass('thick-green-border') &&
|
|
parseInt($('img').css('border-top-width'), 10) >= 8 &&
|
|
parseInt($('img').css('border-top-width'), 10) <= 12
|
|
);
|
|
```
|
|
|
|
La tua immagine dovrebbe avere uno stile `solid` per il bordo.
|
|
|
|
```js
|
|
assert($('img').css('border-right-style') === 'solid');
|
|
```
|
|
|
|
Il bordo attorno al tuo elemento `img` dovrebbe essere verde.
|
|
|
|
```js
|
|
assert($('img').css('border-left-color') === 'rgb(0, 128, 0)');
|
|
```
