====== Creating a Notification theme ======
===== Overview =====
//**Note:** If you want to create a notification theme you will - due to backward-compatibility breakage - have to take into account which version of Gtk+3 the users of your theme will most likely use or have installed.//

Generally speaking, if you want to create a theme for Xfce4-notifyd you have to override the styles of the currently in-use Gtk theme as completely as you can to ensure the user-experience will be consistent with all base themes. 

So, for example, if the user uses ''Adwaita'' (the built-in Gtk+3 default theme) you will have to define everything this theme has in the specific widget styles (see the list of items to match below) to ensure your style will take complete precedence.

**Example:** ''Adwaita'' defines the ''osd'' class shall have a black background and a white foreground color and you only set ''background-color: #ecde00'' (which is yellow) the notification messages will likely be unreadable.


===== Examples =====
For examples of some themes, check [[https://git.xfce.org/apps/xfce4-notifyd/tree/themes]]

Here you will find several .css files that you can use as a starting point for creating your own themes.

//**Note:** The gtk-3.0 folder is for Gtk3.18 and before.//
===== Installing your theme =====
In order for Xfce4-notifyd to find your theme and show it in the [[preferences|Preferences Dialog]], you have to save it as ''gtk.css'' in either ''/usr/share/themes/$yourtheme/xfce-notify-4.0'' (for global installation) or ''~/.themes/$yourtheme/xfce-notify-4.0'' (for local, single-user installation).
