# Centered layout for pages
Before you customize a theme, make a backup. Refer to Shopify help: Duplicating themes (opens new window).
Follow these steps to modify the Cascade page template, to display content in a single column in the center of the page. Make sure to work in a duplicate of the theme so you can easily undo your changes if something goes wrong.
You can make these changes to the main page template or, to create an alternate page with this layout, refer to Shopify partners blog: How to Use Alternate Templates in Shopify Theme Development (opens new window).
In the file Snippets / page__template.liquid, find the two
.grid__itemelements and remove the classes
.lg-up--mt0class on the second
.lg--up--seven-eighthsclass on the top-most
.lg--up--one-half. This prevents the content from becoming too wide.
If you prefer a wider column here, we recommend increasing the font size by referring to Adjust font sizes. This prevents the lines of text from being too long to read comfortably.
Verify that your template’s final code is similar to our page.liquid file on GitHub (opens new window).
