Description

The @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 $i from 1 through 12 {
  .col-#{$i} { width: 100%/12 * $i; }
}

The #{$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 {
  width: 8.33333%;
}

.col-2 {
  width: 16.66667%;
}

...

.col-12 {
  width: 100%;
}

This is a powerful way to create a grid layout. Now you have twelve options for column widths available as CSS classes.

Instructions

Write a @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.

Tests

- text: Your code should use the <code>@for</code> directive.
  testString: 'assert(code.match(/@for /g), ''Your code should use the <code>@for</code> directive.'');'
- text: Your <code>.text-1</code> class should have a <code>font-size</code> of 10px.
  testString: 'assert($(''.text-1'').css(''font-size'') == ''10px'', ''Your <code>.text-1</code> class should have a <code>font-size</code> of 10px.'');'
- text: Your <code>.text-2</code> class should have a <code>font-size</code> of 20px.
  testString: 'assert($(''.text-2'').css(''font-size'') == ''20px'', ''Your <code>.text-2</code> class should have a <code>font-size</code> of 20px.'');'
- text: Your <code>.text-3</code> class should have a <code>font-size</code> of 30px.
  testString: 'assert($(''.text-3'').css(''font-size'') == ''30px'', ''Your <code>.text-3</code> class should have a <code>font-size</code> of 30px.'');'
- text: Your <code>.text-4</code> class should have a <code>font-size</code> of 40px.
  testString: 'assert($(''.text-4'').css(''font-size'') == ''40px'', ''Your <code>.text-4</code> class should have a <code>font-size</code> of 40px.'');'
- text: Your <code>.text-5</code> class should have a <code>font-size</code> of 50px.
  testString: 'assert($(''.text-5'').css(''font-size'') == ''50px'', ''Your <code>.text-5</code> class should have a <code>font-size</code> of 50px.'');'
