how do I get the gallery pictures on the iPhone as wide as the sidebar menu above?
Can you tell me how did you create this gallery, please?
It does not look like from our builder.
no it is a Nextgen Gallery plugin. I think I have to adjust the paddings right left, right?
You can try it, but I do not see any padding that could cause it.
We did not test this plugin, and we do not know how it works and how it builds the gallery.
If you use our gallery instead, it will be extended to the container width.
Or you can control its width in the Advanced tab.
if I want to have the header photo in full width for the iPhone display, i.e. without a border on the right and left on the page http://pixelway.de/projekt-dres-harth/unsere-praxis/, what do I have to do here?
Thanks very much
Please, set the Full Width option for the section that contains this image.
