@for directive adds styles in a loop, very similar to a for loop in JavaScript.
@for is used in two ways: "start through end" or "start to end". The main difference is that "start to end" excludes the end number, and "start through end" includes the end number.
Here's a start through end example:
@for $i from 1 through 12 {The
.col-#{$i} { width: 100%/12 * $i; }
}
#{$i} part is the syntax to combine a variable (i) with text to make a string. When the Sass file is converted to CSS, it looks like this:
.col-1 {This is a powerful way to create a grid layout. Now you have twelve options for column widths available as CSS classes.
width: 8.33333%;
}
.col-2 {
width: 16.66667%;
}
...
.col-12 {
width: 100%;
}
@for directive that takes a variable $j that goes from 1 to 6.
It should create 5 classes called .text-1 to .text-5 where each has a font-size set to 10px multiplied by the index.
@for directive.
testString: 'assert(code.match(/@for /g), ''Your code should use the @for directive.'');'
- text: Your .text-1 class should have a font-size of 10px.
testString: 'assert($(''.text-1'').css(''font-size'') == ''10px'', ''Your .text-1 class should have a font-size of 10px.'');'
- text: Your .text-2 class should have a font-size of 20px.
testString: 'assert($(''.text-2'').css(''font-size'') == ''20px'', ''Your .text-2 class should have a font-size of 20px.'');'
- text: Your .text-3 class should have a font-size of 30px.
testString: 'assert($(''.text-3'').css(''font-size'') == ''30px'', ''Your .text-3 class should have a font-size of 30px.'');'
- text: Your .text-4 class should have a font-size of 40px.
testString: 'assert($(''.text-4'').css(''font-size'') == ''40px'', ''Your .text-4 class should have a font-size of 40px.'');'
- text: Your .text-5 class should have a font-size of 50px.
testString: 'assert($(''.text-5'').css(''font-size'') == ''50px'', ''Your .text-5 class should have a font-size of 50px.'');'
