Specify slidesSpacing in CSS

I can't find any docs/posts on this, so I'm presuming it's not possible to do.
I would like to be able to set the 'slidesSpacing' property via CSS (so that I can take advantage of media queries, and keep all layout values within our scss code rather than our js code).

Could you confirm whether this is possible or not?

    You can't do this. But you can do this via JS:

    var si = $('.royalSlider').data('royalSlider');
    si.ev.on('rsBeforeSizeSet', function() {
        // do some check here, e.g. window width
        si.st.slidesSpacing = 50;

    rsBeforeSizeSet event will fire only when size of slider changed, if you want to trigger it, you need to call updateSliderSize(true);.

    What about slidesSpacing in percents not pixels? Is it possible to set?

    This option is not implemented via CSS as it requires many calculations. You can set this options only in pixels, but you can change it dynamically via CSS.

    Hi Dmitry,

    Could you say more about your last comment on this thread: "you can set this option only in pixels, but you can change it dynamically via CSS"? I'd like to make the space between slides (slidesSpacing) responsive (i.e. increase at certain browser widths and decrease on a mobile device). Thanks for any additional information.

    @tasti.l, Hi, it was a typo, I mean "dynamically via JS". You can do something like:

    var slider = $('.royalSlider').data('royalSlider');
    slider.ev.on('rsBeforeSizeSet', function() {
        slider.st.slidesSpacing = slider.width * 0.02;

    and spacing with equal 2% of slider width.

    Thanks so much for your response, Dmitry. Is it possible to use a similar approach to set a greater slider.width for larger screens, and smaller for small screens, instead of one constant ratio of slider.width to slidesSpacing? Sorry if this is a naive question; I'm new to JS.

    You may use properties like window.innerWidth to retrieve the current width of window.

    Hi again, Dmitry,

    Is there a way to make this work when the slider first loads in addition to when 'rsBeforeSizeSet' fires? For example, I want the slidesSpacing to be 20 percent for mobile and 35 percent for larger screens on initial load. I tried to make the function execute on window load, but I think the slider's default settings override it. Thanks for any advice...

    @tasti.l, calculate the value of slidesSpacing option before slider is intiialized it and set it during the initialization.
