- actual calculates responsive breakpoints that accurately match CSS media queries
- actual is based on this gist
actual(feature, unit="", guess=1, step=*)
- feature: CSS range feature name
- unit: applicable CSS unit (default: unitless)
- guess: initial iteration (default:
1)
- step: step size (default: varies by unit)
- @return number (breakpoint or
0)
- Alias:
actual.actual
actual('width', 'em') // => 87.40625
actual('device-width', 'px') // => 1440
actual('resolution', 'dpi') // => 96
actual('color') // => 10
- Test if a media query is active
- @return boolean
- Alias:
actual.mq
actual.is('tv')
actual.is('(width:30em)')
- Create a partial function that gets a given feature in unit
- @return function
['width', 'height', 'device-width', 'device-height'].map(actual.as('px'))
- Chrome 9+, FF6+, IE9+, Opera 12.1, Safari 5.1 or elsewhere via
matchMedia or msMatchMedia
- Results depend on browser
