bad87fee1348bd9bedf08813	Aggiungere bordi Intorno agli elementi	0	https://scrimba.com/c/c2MvnHZ	16630	add-borders-around-your-elements

--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:

<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:

<img class="class1 class2">

--hints--

Il tuo elemento img dovrebbe avere la classe smaller-image.

assert($('img').hasClass('smaller-image'));

Il tuo elemento img dovrebbe avere la classe thick-green-border.

assert($('img').hasClass('thick-green-border'));

La tua immagine dovrebbe avere uno spessore del bordo di 10px.

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.

assert($('img').css('border-right-style') === 'solid');

Il bordo attorno al tuo elemento img dovrebbe essere verde.

assert($('img').css('border-left-color') === 'rgb(0, 128, 0)');
