# --description--
|
|
|
|
There are several default fonts that are available in all browsers. These generic font families include `monospace`, `serif` and `sans-serif`.
|
|
|
|
When one font isn't available, you can tell the browser to "degrade" to another font.
|
|
|
|
For example, if you wanted an element to use the `Helvetica` font, but degrade to the `sans-serif` font when `Helvetica` isn't available, you will specify it as follows:
|
|
|
|
```css
|
|
p {
|
|
font-family: Helvetica, sans-serif;
|
|
}
|
|
```
|
|
|
|
Generic font family names are not case-sensitive. Also, they do not need quotes because they are CSS keywords.
|
|
|
|
# --instructions--
|
|
|
|
To begin, apply the `monospace` font to the `h2` element, so that it now has two fonts - `Lobster` and `monospace`.
|
|
|
|
In the last challenge, you imported the `Lobster` font using the `link` tag. Now comment out that import of the `Lobster` font (using the HTML comments you learned before) from Google Fonts so that it isn't available anymore. Notice how your `h2` element degrades to the `monospace` font.
|
|
|
|
**Note:** If you have the `Lobster` font installed on your computer, you won't see the degradation because your browser is able to find the font.
|
|
|
|
# --hints--
|
|
|
|
Your h2 element should use the font `Lobster`.
|
|
|
|
```js
|
|
assert(
|
|
$('h2')
|
|
.css('font-family')
|
|
.match(/^"?lobster/i)
|
|
);
|
|
```
|
|
|
|
Your h2 element should degrade to the font `monospace` when `Lobster` is not available.
|
|
|
|
```js
|
|
assert(
|
|
/\s*h2\s*\{\s*font-family\s*\:\s*(\'|"|)Lobster\1\s*,\s*monospace\s*;?\s*\}/gi.test(
|
|
code
|
|
)
|
|
);
|
|
```
|
|
|
|
You should comment out your call to Google for the `Lobster` font by putting `<!--` in front of it.
|
|
|
|
```js
|
|
assert(new RegExp('<!--[^fc]', 'gi').test(code));
|
|
```
|
|
|
|
You should close your comment by adding `-->`.
|
|
|
|
```js
|
|
assert(new RegExp('[^fc]-->', 'gi').test(code));
|
|
```
