Exploring the world of SCSS by manipulating variables and arrays

Working with gulp for sprite creation, I encountered an issue with one of the images.

$s-ico-webdesign: '442px', '0px', '-442px', '0px', '60px', '60px', '538px', '519px', 'sprite.png';

The data in this array represents the sprite image. In order to set the margin-top as half of the height of a sprite element, I have created the following mixin:

@mixin sprite-top-half-margin($sprite) {
  $height: #{nth($sprite, 6)} / 2;
  margin-top : $height;
}

In my code snippet, I am trying to implement this mixin like so:

.add-nav .sub-menu .web-design a:before {
  @include sprite($s-ico-webdesign);
  @include sprite-top-half-margin($s-ico-webdesign);
  left:22px;
}

However, the margin-top property is not compiling as expected. Can anyone point out where I may be going wrong?

Answer №1

Your code is throwing a casting error due to #{nth($sprite, 6)} returning a string value. This prevents Sass from performing any mathematical operations on it.

To resolve this issue, you can utilize the string-to-number parser. I have implemented this solution using sassmeister tool by Hugo Giraudel

I have created a gist containing the solution for you:

The crucial part of the solution is outlined below:

@mixin sprite-top-half-margin($sprite) {
  $height: to-number(nth($sprite, 6)) / 2;
  margin-top : $height;
}

The expected output should be as follows:

.add-nav .sub-menu .web-design a:before {
  margin-top: 30px;
  left: 22px;
}
