Responsive HTML5 outputs have proved very popular as with little input from the author, the layout adapts to the user's screen, be that a computer, a tablet or a smartphone. All the author has to do is customise the layout if required.
Click Output > Output Settings the first time you generate so that you can configure your preset as required. After the preset is configured, you can either come back here next time or you can click the Quick Generate icon top right in Adobe RoboHelp 2019.
The options are similar to previous versions and are described in detail in the online help.
The icons above the list of presets allow you to generate an output,
view it or create further outputs.
