1) How do I set my content width exactly at 600px and sidebar at 300px? (what should be my container width and what should be the percentage of my sidebar?).
This sidebar width in percentages doesn’t really make sense to me…
2) How do I set different spacing between the content and the sidebar? I want to adjust the spacing between my content area and the right sidebar, without adjusting the spacing between my sidebar widgets.
Not sure why you only let the user set a unified spacing.
