Using `inherit` is IMHO more expressive since it means "use the color of
the parent element".
This is particularly useful for CONSUL installations using custom
styles. Consider the following code:
```
h2 {
color: $white;
a {
color: $white;
}
}
```
If we'd like to customize the way headings look, we'd have to override
two colors:
```
h2 {
color: $red;
a {
color: $red;
}
}
```
Consider the scenario where we use `inherit`:
```
h2 {
color: $white;
a {
color: inherit;
}
}
```
Now we only need to override one color to change the styles:
```
h2 {
color: $red;
}
```
Note we're absolutely positioning the link instead of the icon; that way
keyboard users will be able to focus on the icon. Until now, users would
focus on an empty link.
For the same reason, we couldn't use `click_link` with Capybara, since
it would fail to click an empty link. Now we can.
