I would like to know how to make changes on the layout size - how can I reduce the space between the page and the layout edge where background appears; - regading layout, I would like to know how can I increase the width size of layout where my articles are posted and also how to increase the size of the right sidebar.
I am interested that all these changes made to be visible on desktop mode, I suppose on mobile there should not be visible any difference.
I attached a picture for better understanding. It is from desktop mode view, on my laptop.
