Options

data attributes

You can control parallax effect by data-paroller-* or jQuery values.

data-paroller-factor

Sets speed and distance of element's parallax effect on scroll. Value can be positive (0.3) or negative (-0.3). Less means slower. Different sign (+/-) means different direction (up/down, left/right).

⚠️ Since factor is multiplier it must be set for paroller.js to have parallax effect.

data-paroller-factor-*

Sets paroller factor for selected breakpoint.

data-paroller-transition

Only effects elements with paroller.js type set to foreground!
### JavaScript
javascript // initialize paroller.js and set attributes for selected elements $(".paroller, [data-paroller-factor]").paroller({ factor: 0.2, // multiplier for scrolling speed and offset, +- values for direction control factorLg: 0.4, // multiplier for scrolling speed and offset if window width is less than 1200px, +- values for direction control type: 'foreground', // background, foreground direction: 'horizontal', // vertical, horizontal transition: 'translate 0.1s ease' // CSS transition, added on elements where type:'foreground' });
##### Set factor breakpoints

javascript // initialize paroller.js and set attributes for selected elements $(".paroller, [data-paroller-factor]").paroller({ factor: 0.3, // +/-, if no other breakpoint factor is set this value is selected factorXs: 0.1, // factorXs, factorSm, factorMd, factorLg, factorXl factorSm: 0.2, // factorXs, factorSm, factorMd, factorLg, factorXl factorMd: 0.3, // factorXs, factorSm, factorMd, factorLg, factorXl factorLg: 0.4, // factorXs, factorSm, factorMd, factorLg, factorXl factorXl: 0.5 // factorXs, factorSm, factorMd, factorLg, factorXl type: 'foreground', // background, foreground direction: 'horizontal',// vertical, horizontal transition: 'translate 0.1s ease' // CSS transition, added on elements where type:'foreground' });
