Artboard

Artboard is a simple way to add a checkered grid to any HTML element with CSS or SCSS. The intended use case is to provide a grid for creating art assets in HTML, CSS and JavaScript.

Inspiration

The approach of using a gradient as a background is borrowed from this ingenious hack from user3061127 on Stack Overflow.

Installation

npm install artboard

Usage

Basic

To add a simple 10x10 grid with divider lines after every ten grid lines, just import the CSS:

`` html

`

And give a tag the artboard-grid class:

` html

`

$3

To add a transparent overlay to the whole HTML document, just add a div with the artboard-overlay class:

` html



`

Custom

The grid can be compiled with custom values by importing artboard into an SCSS file:

` css
@import '[path to artboard]/artboard';
`

A custom grid can be constructed by setting these variables:

` css
/ Space between grid lines /
$artboard-grid-px: 10px;
/ Color of grid lines /
$artboard-grid-color: rgba(0, 0, 0, .25);
/ Number of grid lines between divider lines /
$artboard-divider-interval: 10;
/ Color of divider lines /
$artboard-divider-color: rgba(0, 0, 0, .5);

/ Note that the above variables must be set before importing artboard /
@import '[path to artboard]/artboard';
`

The grid can be then be included using a CSS style:

` html

`

A SCSS mixin:

` css
body {
@include artboard-grid();
}
`

Or an SCSS @mixin with custom values:

` css
body {
/ @mixin artboard-grid($grid-px: $artboard-grid-px, $grid-color: $artboard-grid-color, $divider-interval: $artboard-divider-interval, $divider-color: $artboard-divider-color) { /
@include artboard-grid(10px, rgba(0, 0, 0, .25), 10, rgba(0, 0, 0, .5));
}
`

$3

The artboard overlay's opacity can also be changed with a variable:

` css
$artboard-overlay-opacity: .5;

/ Note that the above variable must be set before importing artboard /
@import '[path to artboard]/artboard';
`

Or included with a @mixin:

` css
.grid {
/ @mixin artboard-overlay($opacity: $artboard-overlay-opacity, $grid-px: $artboard-grid-px, $grid-color: $artboard-grid-color, $divider-interval: $artboard-divider-interval, $divider-color: $artboard-divider-color) { /
@include artboard-overlay(.2);
}
``

Example

One advantage to creating assets in HTML, CSS and JavaScript is that scalable graphics can be created alongside animation logic that also scales. In the included example, animated HTML elements are positioned on the grid; changing the grid size also changes the positions of all these elements, as well as the animation, while everything continues to remain in scale.
