Hi @bigdreams,
Thank you for reaching out to us. This would require custom CSS as this is not a theme feature by default and is outside of our support scope, but we will do our best to help you getting started with the customization but we will not be able to implement it.
- To apply the CSS on specific pages, you need to get the page ID first, please see https://theme.co/docs/how-to-locate-post-ids then with the page ID you can target the page container
.x-container.max.width for example .page-id-2276 .x-container.max.width to give it more width than the selected one in the theme options. You can find the selector by inspecting the page in Chrome developers tool:
- You can reduce the spacing between sidebar and main content by increasing the width of the main content:
Make sure to target the main container with the page ID so the CSS is not applied globally. Here are some related links for further reading, this could help you in finding and implementing some CSS fixes:
Hope this helps!
