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)');
