Hi there,
if you’re wanting to have Full width content, or mixed width content then our recommendation is:
1. Enable the Full Width option using the Page Builder Container:
https://docs.generatepress.com/article/page-builder-container/
This will set the Page to full width and remove the padding.
2. Use the GenerateBlocks plugin:
https://wordpress.org/plugins/generateblocks/
You can now add Container Blocks – that you can control the container width, padding and many other styles.
