Here is a copy/paste from a comment I’ve previously made here – https://appfinite.com/topic/genesis-responsive-slider-off-center/#post-6574
“the Genesis Responsive Slider images don’t center, they float left or right, but they don’t center. This isn’t caused by the theme or anything, that’s just the way the plugin itself is designed. You can change the width to 1140px to fill in the entire space which will make it appear as centered.
You should also download and run a plugin called Regenerate Thumbnails anytime you change or add your image sizes. This will adjust everything instantly for you so you don’t have to wait for the images to resize.”
I’d recommend moving the slider inside of the “Slider” widget instead of the “Slider Wide” widget area if your slider is going to be the same width as the rest of the content (which is 1140px). If you add it in the “Slider” widget area then it will appear centered since that widget area is designed to be in the middle. Anything you add inside of the widget area will center by default, unless you have something like this particular slider that doesn’t allow centering. Hope this helps.
