Why is it not possible to set the page container to 100% width ?
The suggestion below seems counter intuitive!
You can adjust the width of your overall site container inside Appearance > Customize > Layout > Container.
You can use the slider to adjust the width in pixels, or directly input your number into the field.
You can set it to a percentage using CSS, however I typically recommend choosing a really high pixel value like 2000 if you’re looking for a 100% width website. Since GeneratePress is responsive, it will be 100% wide on most screens at that width.
I don’t see how it would look any more weird on a 60″ tv than on my 27″ monitor, 4k is 4k regardless and a fixed pixel value on a 60″ screen is going to seem a lot larger no matter what you set it to because the pixel pitch is higher.
My intention is to use a pagebuilder (wpbakery/visual composer) and specify containers with percentage borders and margins. I’m not sure how they two will interact to it seemed logical to set the base theme to 100% width and then adjust everything else on top.
