meteor slides Remove white background

Hi Décio, you have some code tags wrapped around your shortcode, switch to the HTML view instead of the visual editor and you’ll see these code tags, if you remove these it should layout better.

You can change the size of the slideshow in the slideshow settings, It works best if you update the slideshow dimensions, then upload slide images that match those dimensions exactly. But the width of the slideshow will scale to fit the width of the theme you add it to, if you want it wider, you have to edit the theme’s width.
