# --description--
|
|
|
|
La propiedad `opacity` en CSS se usa para ajustar la opacidad o, por el contrario, la transparencia de un elemento.
|
|
|
|
<blockquote>Un valor de 1 es opaco, que no es transparente en absoluto.<br>Un valor de 0.5 es la mitad transparente.<br>Un valor de 0 es completamente transparente.</blockquote>
|
|
|
|
El valor dado se aplicará a todo el elemento, ya sea una imagen con cierta transparencia, o los colores de primer plano y fondo para un bloque de texto.
|
|
|
|
# --instructions--
|
|
|
|
Establece la `opacity` de las etiquetas de anclajes en 0.7 usando la clase `links` para seleccionarlas.
|
|
|
|
# --hints--
|
|
|
|
Tu código debe establecer la propiedad `opacity` en 0.7 en las etiquetas de anclajes seleccionando la clase de `links`.
|
|
|
|
```js
|
|
assert(
|
|
/\.links\s*{([\s\S]*?;)*\s*opacity\s*:\s*0*\.70*\s*(;[\s\S]*?|\s*)}/.test(
|
|
$('style').text()
|
|
)
|
|
);
|
|
```
