Sharepoint 2010 UI Customizations – Hide Entire Ribbon On a Single Page

I found myself in a scenario that required me to hide the entire ribbon from the New Item form in SharePoint. Below is a simple solution to this issue.

1) Open the list file in SharePoint Designer and open in advanced mode.
2) Under the Manage Styles window, select New Style.

3) Add the style #s4-ribbonrow and apply the attribute (display: none;).

4) Save the .aspx file and view it in your browser.
