|
0 |
Description
extend
that makes it easy to borrow the CSS rules from one element and build upon them in another.
For example, the below block of CSS rules style a .panel
class. It has a background-color
, height
and border
.
.panel{Now you want another panel called
background-color: red;
height: 70px;
border: 2px solid green;
}
.big-panel
. It has the same base properties as .panel
, but also needs a width
and font-size
.
It's possible to copy and paste the initial CSS rules from .panel
, but the code becomes repetitive as you add more types of panels.
The extend
directive is a simple way to reuse the rules written for one element, then add more for another:
.big-panel{The
@extend .panel;
width: 150px;
font-size: 2em;
}
.big-panel
will have the same properties as .panel
in addition to the new styles.
Instructions
.info-important
that extends .info
and also has a background-color
set to magenta.
Tests
tests:
- text: Your <code>info-important</code> class should have a <code>background-color</code> set to <code>magenta</code>.
testString: assert(code.match(/\.info-important\s*?{[\s\S]*background-color\s*?:\s*?magenta\s*?;[\s\S]*}/gi), 'Your <code>info-important</code> class should have a <code>background-color</code> set to <code>magenta</code>.');
- text: Your <code>info-important</code> class should use <code>@extend</code> to inherit the styling from the <code>info</code> class.
testString: assert(code.match(/\.info-important\s*?{[\s\S]*@extend\s*?.info\s*?;[\s\S]*/gi), 'Your <code>info-important</code> class should use <code>@extend</code> to inherit the styling from the <code>info</code> class.');
