Click on the "Document Types" link in the folder tree. Click the Document Type file that will be changed so the Definition File, Edit Layout File, and Deploy Layout Files can be seen. Click the arrow next to the layout file that is to be changed, and click the "Select new File" option from the context menu.
If you open the user settings screen in the ALM shell and click on the Landing Page button the Layout screen says empty. Even after making changes and then clicking Save your changes aren't saved.
Depending on whether you use master pages or not just make sure to only have one set of <title> tags either in the master page or the deploy layout file. If you have the preceding code in the master page but have a blank set of <title></title> tags in the deploy layout file then when the file is deployed there will actually be two sets of title tags in the code of the deployed page but the browser will use the second set which would appear empty in the title bar.
The <!DOCTYPE html> tag has been added to most end-user browser templates to support HTML5 capabilities. For this release, HTML5 capabilities are used for the Rich Text editor and form styling and layout improvements.
This line should be added to the <head> section of the CCS deploy layout and CCS edit layout files or the masterpage attached to the layout files. In many cases the two layout files will be the same depending on how the CCS document was initially setup.
