    'defaultWidth XSw1 SMw2 MEw3 LAw4 XLw5' where w1 to w5 are the thumbnails widths for resolutions XS to XL.
     
  • and for thumbnailHeight
    'defaultHeight XSh1 SMh2 MEh3 LAh4 XLh5' where h1 to h5 are the heights for resolutions XS to XL.

Thumbnail touch and hover effects


These effects are triggered on mouse over or on touch-tap. They are defined with the thumbnailHoverEffect2 parameter.

Presets:

You can set one or multiple presets to the thumbnailHoverEffect2 with the syntax thumbnailHoverEffect2: 'preset1|preset2|...'

Possible presets:

  • Image: 'imageBlurOn', 'imageBlurOff', 'imageGrayOn', 'imageGrayOff', imageSepiaOn', 'imageSepiaOff', 'imageScale150', 'imageScaleIn80', 'imageScale150Outside', 'imageSlideUp', 'imageSlideDown', 'imageSlideRight', 'imageSlideLeft'
  • Tools: 'toolsAppear', 'toolsSlideDown', 'toolsSlideUp'
  • Label: 'labelAppear', 'labelAppear75', 'labelOpacity50', 'scaleLabelOverImage', 'descriptionAppear', 'labelSlideUpTop', 'labelSlideUp', 'labelSlideDown', 'descriptionSlideUp'
  • Thumbnail: 'scale120'
  • Border: 'borderLighter', 'borderDarker'
  • Misc: 'overScale', 'overScaleOutside', 'slideUp', 'slideDown', 'slideRight', 'slideLeft'

Usage example: thumbnailHoverEffect2: 'borderDarker|labelAppear75'


Advanced usage

For a full control of the effects, use the syntax thumbnailHoverEffect2: 'effect1|effect2|...' where effectN has the syntax [element]_[property]_[fromValue]_[toValue]
view demo on codepen

  • [element]: element to apply the transformation. Possible values: thumbnail, image, label, description, title, tools, customlayer
  • [property]: any css proprety to transform
    • for CSS transform property, just use the transform-function. Limited to: translateX, translateY, rotateX, rotateY, rotateZ, scale
      Example: image_rotateZ_0deg_15deg
    • for CSS filters, just use the visual effect. Limited to: blur, brightness, grayscale, sepia, contrast, opacity, saturate
      Example: 'image_grayscale_0%_100%
  • [fromValue]: initial value
  • [toValue]: value at the end of the transformation

Some examples:

  • One hover effect:
    • Remove the sepia filter on the image: thumbnailHoverEffect2: 'image_sepia_100%_1%'
    • Apply a blur filter on the image: 'image_blur_0.00px_2.00px'
    • Rotate the image from 0degre to 15degre: 'image_rotateZ_0deg_15deg'
    • Apply a grayscale filter the image: 'image_grayscale_0%_100%'
    • Zoom the image in: image_scale_1.00_1.20
    • Zoom the image out: image_scale_1.20_1.00
    • Change the transparency of label background: 'label_backgroundColor_rgba(255,255,255,0.80)_rgba(255,255,255,0.01)'
    • Apply a red colorization on the image: customlayer_backgroundColor_rgba(160,0,0,0.0)_rgba(160,0,0,0.5)
    • Change the transparency of the icons: tools_opacity_1_0.5
    • Change the image contrast: image_contrast_1_4
    • Change the image brightness: image_brightness_1_2
  • Two hover effects:
    • Apply a grayscale filter and rotate the image: thumbnailHoverEffect2:'image_grayscale_0%_100%|image_rotateZ_0deg_15deg'


    Initialization In some case, it's interesting to set CSS properties but without any animation.
    For this, use the option thumbnailBuildInit2: : 'init1|init2|...' where initN has the syntax: [element]_[property]_[Value].
    Example : thumbnailBuildInit2: 'image_scale_1.20'


    Additional tuning

    Fine tuning settings: duration, delay, easing, back duration, back delay, beack easing, hoverin, hoverout, first keyframe
    syntax: thumbnailHoverEffect2: { name: '[effectName]', delay: 0, duration: 400, easing: 'easeOutQuart', delayBack: 0, durationBack: 300, easingBack: 'easeOutQuart', hoverin: true, hoverout: true, firstKeyframe: true }
    where:

    • duration: the duration of the effect in ms
    • delay: the delay in ms before the transformation is started
    • easing: specify the rate of change of the transformation over time (see easings.net)
      • Possible values:
        easeInQuad, easeOutQuad, easeInOutQuad, easeInCubic, easeOutCubic, easeInOutCubic, easeInQuart, easeOutQuart, easeInOutQuart, easeInQuint, easeOutQuint, easeInOutQuint, easeInSine, easeOutSine, easeInOutSine, easeInExpo, easeOutExpo, easeInOutExpo, easeInCirc, easeOutCirc, easeInOutCirc, easeOutBounce, easeInBack, easeOutBack, easeInOutBack, elastic, bounce
    • durationBack: duration of the effect to initial state, in ms
    • delayBack: start delay back transformation in ms
    • easingBack: easing used for the back transformation
    • hoverin: used on hover in
    • hoverout: used on hover out
    • firstKeyframe: used for chained animations
    Note: name is the only mandatory proprety.
    Some examples:
    • thumbnailHoverEffect2: { name: 'imageBlurOn', duration: 800, easing: 'easeInCubic', delayBack: 0, durationBack: 300, easingBack: 'easeOutQuart' }
    • thumbnailHoverEffect2: { name: 'image_rotateZ_0deg_15deg', duration: 800, durationBack: 500}
    • combination of 2 effects: thumbnailHoverEffect2: [{ name: 'image_scale_1.00_1.20', duration: 500}, { name: 'image_rotateZ_0deg_15deg', delay: 500}]



    Stacks

    Stacks can be added behind thumbnails to create nice hover effects. Their color is defined in the colorScheme.
    Use thumbnailStacks and thumbnailL1Stacks to define then number of stacks.

    The thumbnail animation is applied to the stack, but with a percent value.
    For example, if thumbnailStacksRotateX is set to 0.4, then the 1st stack will have a percent of 0.6 applied to the rotationX value of the thumbnail.
    For the second stack, the percent will be 0.2, for the third one it will be -0,2, and so on.

    Possible parameters to set these percents: 'thumbnailStacksTranslateX', 'thumbnailStacksTranslateY', 'thumbnailStacksTranslateZ', 'thumbnailStacksRotateX', 'thumbnailStacksRotateY', 'thumbnailStacksRotateZ', 'thumbnailStacksScale'

    Color schemes


    Color schemes allow you to customize some elements without changing the CSS file.
    Two separated color schemes can be set: one for the gallery (colorScheme), and one for the lightbox (colorSchemeViewer).
    For each one, 2 templates can be used: dark (default valude) and light. You can create your own color scheme.

    Example:
    To change the backrgound and the boder color of the thumbnails
    1. define one color scheme: var myCS= { thumbnail : { background: '#F00', borderColor: '#F00' } };
    2. assign it to the gallery: colorScheme: myCS

    Gallery color scheme format (with default values):

    {
      navigationBar : { background: 'none', borderTop: '', borderBottom: '', borderRight: '', borderLeft: '' },
      navigationBreadcrumb : { background: '#111', color: '#fff', colorHover: '#ccc', borderRadius: '6px' },
      navigationFilter : { color: '#ddd', background: '#111', colorSelected: '#fff', backgroundSelected: '#111', borderRadius: '6px' },
      thumbnail : { background: '#000', borderColor: '#000', labelOpacity : 1, labelBackground: 'rgba(34, 34, 34, 0)', titleColor: '#eee', titleBgColor: 'transparent', titleShadow: '', descriptionColor: '#ccc', descriptionBgColor: 'transparent', descriptionShadow: '', stackBackground: '#aaa' },
      thumbnailIcon : { padding: '5px', color: '#fff' },
      pagination : { background: '#111', backgroundSelected: '#666', color: '#fff', borderRadius: '4px', shapeBorder: '3px solid #666', shapeColor: '#444', shapeSelectedColor: '#aaa'}
    }
        

    Lightbox color scheme format (with default values):

    {
      background: '#000', imageBorder: 'none', imageBoxShadow: 'none',
      barBackground: 'rgba(4, 4, 4, 0.7)', barBorder: '0px solid #111', barColor: '#eee', barDescriptionColor: '#aaa'
    }

    Tips and tricks


    Recommandations / Performances / FAQ

    Thumbnails hover effects:

    • do not combine too much effects (smooth animation on a computer may be slow on a mobile device).
    Self hosted images:
    • define each thumbnail's size.
    • define each image's size.
    Social sharing
    • Assign an ID to the DIV containing the gallery.
    • Each album and image must have an ID defined.
    • IDs should never been changed.








    Security


    By default, HTML tags cannot be used in titles and descriptions of images.
    To enable HTML tags, set the option allowHTMLinData: true.
    Be aware that this could lead to XSS (cross site scripting) vulnerability.
