I’m trying to make a section full width while keeping the content boxed. So far I have not succeeded. In Gutenberg I drop a Cover block, set it to full width and type some text in the paragraph block that’s inside. In the editor looks good, but when I preview it everything looks full width, both the cover block and its contents. However, if I switch to Twenty Nineteen, the page looks good. I’m working locally with GP 2.3.2 only (no Premium), Gutenberg 6.5.0 (plugin). Also have CoBlocks installed, but made no difference if activated.
