GridHelper
The GridHelper
class is a utility that creates an overlay grid for web development, allowing designers and developers to visualize the grid structure based on design guidelines. It provides easy toggling and responsiveness based on screen breakpoints.
Features
- Toggle the grid visibility with
Control + g
(customizable key). - Define grid structure: number of columns, gutter width, margin, color, and opacity.
- Supports custom breakpoints, allowing different grid configurations at various screen widths.
- Automatically updates the grid when the window is resized.
Installation
npm install @locomotivemtl/grid-helper
Usage
Basic Example
To initialize the grid with default settings:
const gridHelper = new GridHelper();
Custom Configuration
You can provide a custom configuration to adjust the grid properties:
const gridHelper = new GridHelper({
columns: 4,
gutterWidth: '10px',
marginWidth: '10px',
color: 'blue',
opacity: 0.2,
key: 'g',
breakpoints: {
'768': { columns: 8, gutterWidth: '15px' },
'1024': { columns: 12, gutterWidth: '20px' }
}
});
You can also use CSS variables to bind them with your CSS logic, especially for columns
, gutterWidth
, and marginWidth
. This can be useful in cases where you dynamically update CSS variables within media queries.
const gridHelper = new GridHelper({
columns: 'var(--grid-columns)',
gutterWidth: `var(--grid-gutter)`,
marginWidth: `var(--grid-margin)`,
});
