#Sass Baseline Mixin

A very simple Baseline SCSS mixin for providing a visual baseline in your project, in CSS.

##The Mixin

In the mixin it has two arguments, $baseline-height and $baseline-color. These are set to defaults in the mixin, but feel free to change it to any colour and line-height you like.

##Usage in projects

When using the mixin, you may want to set a condition for showing the grid, such as this:

// style.scss
$show-baseline: true!default; //Set to false when not in use.

body {
	//...add your body styles here

	@if $show-baseline == true {
		// Include the baseline mixin
		@include baseline;
	}
}

And then you should have a suitable baseline for your project! Have fun!

_baseline.scss

// Set up line-height and colour defaults for this mixin.
$line-height: 20px!default;
$line-color: #94d4ff!default;
