# --description--
|
|
|
|
The `opacity` property in CSS is used to adjust the opacity, or conversely, the transparency for an item.
|
|
|
|
<blockquote>A value of 1 is opaque, which isn't transparent at all.<br>A value of 0.5 is half see-through.<br>A value of 0 is completely transparent.</blockquote>
|
|
|
|
The value given will apply to the entire element, whether that's an image with some transparency, or the foreground and background colors for a block of text.
|
|
|
|
# --instructions--
|
|
|
|
Set the `opacity` of the anchor tags to 0.7 using `links` class to select them.
|
|
|
|
# --hints--
|
|
|
|
Your code should set the `opacity` property to 0.7 on the anchor tags by selecting the class of `links`.
|
|
|
|
```js
|
|
assert(
|
|
/\.links\s*{([\s\S]*?;)*\s*opacity\s*:\s*0*\.70*\s*(;[\s\S]*?|\s*)}/.test(
|
|
$('style').text()
|
|
)
|
|
);
|
|
```
