How do i edit the margin on the left and right?

Topic summary

Issue: On desktop, all sections share the same left/right margins, creating a rigid straight line. Goal is to adjust margins per section without affecting mobile.

Info shared: Store URL was provided upon request.

Proposed fix (global desktop tweak): Edit the theme CSS (Online Store > Themes > Assets > main.css/base.css/style.css/theme.css) and add a rule targeting the desktop slider component and the multicolumn isolate to set max-width: 100%.

Result: Desktop components expand to full width; a screenshot was shared to confirm the change. The OP reported success.

Follow-up: For section-specific changes, the guidance was to find the exact selector controlling that section’s width and override it accordingly. No detailed steps or mobile-specific safeguards (e.g., media queries) were provided.

Status: Partially resolved. A general CSS solution improved desktop layout; precise per-section margin control remains insufficiently detailed, so the discussion appears open.
