This page is used to tailor the calendar's user interface colors, font family and font sizes.

Buttons and drop-down menu at the top of the page:

Preview Theme: When pressed, the theme displayed in this window will be temporary activated for the calendar and a Stop Preview button will be displayed. The calendar can now be browsed with these styles, until the Stop Preview button is selected.
Save Theme: The displayed theme will be saved to the database and from now on this theme will be used by the calendar. The previous theme in the database will be overwritten. When the theme is saved for the first time since the Styling page is opened, prior to overwriting the theme in the database, an automatic backup will be stored in a file in the css folder; the file extension will be "abak".
Backup Theme: The theme from the database will be stored in a file in the css folder. The name given to the file will be shown in the information line at the top of the window. The file extension will be "mbak".
Restore Theme: This drop-down menu will show the LuxCal default theme and all backup files (".abak" and ".mbak") in the css folder. When an entry is selected the theme from the selected file will be displayed in the Styling page. This theme can then be previewed, modified and saved.
Close Window: Close the Styling window. If there are unsaved changes, a warning will be displayed.
Theme title: Optional theme title which will be stored along with the styles in the database and in backup files. If left blank, this field will default to the calendar title.

Styles:

font sizes: Some font sizes are specified in px (pixels) and some in em. When specified in px, the font size is fixed and when specified in em, the font size is scalable and equals: base font size x number of ems.
bars, headers and rules: The navigation bar, the footer bar, table headers and lines.
popup windows: The event Add/Edit window and the Help window.
insert boxes: Boxes on various pages, which have no shadow. E.g. the login box on the log in page.
overlay boxes: Boxes which overlay the page and have no shadow. E.g. the Options panel, the Todo sidebar, the upcoming side bar.
content offset: The number of pixels the actual calendar content starts under the navigation bar. In certain cases, for instance when you want to add elements at the top of the calendar, you may want to shift the calendar content down by increasing its offset from navigation bar.
