Total includes a powerful function so you can easily tweak the widths of your site (main/content/sidebar) for all responsive sizes. All you need to do is go to Appearance -> Customize -> Layout to tweak your layouts and view the changes live.
- Container Width: Your site width (all content).
- Content Width: The area with the content when your left or right sidebar is enabled.
- Sidebar Width: Your sidebar width.
This is the width of your site. You can use pixels or percentages for the value. There isn’t any max or minimum.
The “content” area just like the name suggests is the area where you content is.
And the “sidebar” is your main sidebar.
Since version 3.0.0 of Total the theme was changed to a fluid layout so there is a max with of 90% on the main container. This makes it so even if you set your layout to be 3000px wide it will never go past 90% of your window width so as you resize your browser your site content will always be visible. This can be altered at Appearance > Customize > Layout > General.
