keywords. In Sass, variables start with a $
followed by the variable name.
Here are a couple examples:
$main-fonts: Arial, sans-serif;One example where variables are useful is when a number of elements need to be the same color. If that color is changed, the only place to edit the code is the variable value.
$headings-color: green;
//To use variables:
h1 {
font-family: $main-fonts;
color: $headings-color;
}
$text-color
and set it to red. Then change the value of the color
property for the .blog-post
and h2
to the $text-color
variable.
$text-color
with a value of red.
testString: 'assert(code.match(/\$text-color:\s*?red;/g), ''Your code should have a Sass variable declared for $text-color
with a value of red.'');'
- text: Your code should use the $text-color
variable to change the color
for the .blog-post
and h2
items.
testString: 'assert(code.match(/color:\s*?\$text-color;/g), ''Your code should use the $text-color
variable to change the color
for the .blog-post
and h2
items.'');'
- text: Your .blog-post
element should have a color of red.
testString: 'assert($(''.blog-post'').css(''color'') == ''rgb(255, 0, 0)'', ''Your .blog-post
element should have a color of red.'');'
- text: Your h2
elements should have a color of red.
testString: 'assert($(''h2'').css(''color'') == ''rgb(255, 0, 0)'', ''Your h2
elements should have a color of red.'');'
