# --description--

|

Man kann die Breite eines Elements in CSS mit der `width`-Eigenschaft festlegen. Werte können in relativen Längeneinheiten (z. B. `em`), absoluten Längeneinheiten (z. B. `px`) oder als Prozentsatz seines übergeordneten Elements angegeben werden. Hier ein Beispiel, in dem die Breite eines Bildes auf 220px geändert wird:
|
||
|
|
|
||
|
|
```css
|
||
|
|
img {
|
||
|
|
width: 220px;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
# --instructions--
|
||
|
|
|
||
|
|
Füge der Karte eine `width`-Eigenschaft hinzu und setzte den Wert der Gesamtbreite auf 245px. Verwende die `fullCard` (dt. ganze Karte) Klasse, um das Element auszuwählen.
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
Dein Code sollte die `width`-Eigenschaft der Karte auf 245px ändern, indem du den `fullCard`-Klassenselektor verwendest.
|
||
|
|
|
||
|
|
```js
|
||
|
|
const fullCard = code.match(/\.fullCard\s*{[\s\S]+?[^}]}/g);
|
||
|
|
assert(
|
||
|
|
fullCard &&
|
||
|
|
/width\s*:\s*245px\s*(;|})/gi.test(fullCard[0]) &&
|
||
|
|
$('.fullCard').css('maxWidth') === 'none'
|
||
|
|
);
|
||
|
|
```
