I am working on
I want the white rectangle at center to fill the entire screen's width.
I created a child theme (zeenoble-child) and have been fiddling with #wrapper, #content, .fullwidth and .template-fullwidth in the child theme editor, changing width to larger px or changing width to min-width=100%.
No luck yet.
Could anyone give some tips on this? I am new to WordPress and self-taught, so I have holes in my knowledge.
One confusion is that template-fullwidth is its own .php file not referenced actually within the parent theme. Not sure why this is, but maybe it's a clue to how to manipulate this.
