An HTML file is designated for mobile output when the Enable mobile property is set to Yes. This designation enables a Mobile Layout option, where you can edit and preview your mobile output.

Note: An HTML file that has Mobile Layout enabled can additionally be viewed on a desktop or tablet. In these cases, page design is derived from the HTML canvas and the page design on the Mobile Layout is ignored. This eliminates the need to maintain different copies of the same pages for different output.

You can enable mobile output for an existing HTML file, or create a new file with mobile output enabled.
