If you change the width of a screen profile, the media query for that screen profile defined in the style sheet becomes undefined. RoboHelp does not automatically update the media query.
To map the styles of an undefined media query to a media, follow these steps:
1)Right-click the CSS file and select Edit.
2)In the Styles dialog box, select Manage Media Queries from the Media list.
3)Select the undefined media query with the width you specified and click Map.
4)Select the screen profile.
To delete the styles of a media query, select the media query in the Manage Media Queries dialog box, and click Delete.
