Trilium now has basic support for right-to-left text, at note level.

+
+ + + + + + + +
+
+ +
+ 		+
+ +
+
+
+

Note that only the Text note type supports this.

+

The list of languages is configurable via the a new dedicated settings + page:

+
+ +
+

To select the corresponding language of the text, go to “Basic Properties” + and select your desired language.

+

+ +

+

Feel free to report any issues regarding right to left support.

Creating a custom theme

- -
-

Step 1. Find a place to place the themes

-

Organization is an important aspect of managing a knowledge base. When - developing a new theme or importing an existing one it's a good idea to - keep them into one place.

-

As such, the first step is to create a new note to gather all the themes.

-

- -

-

Step 2. Create the theme

-
- - - - - - - - - - - - - - - - - - - -
-
- -
- 		Themes are code notes with a special attribute. Start by creating a new - code note.
-
- -
- 		Then change the note type to a CSS code.
-
- -
- 		In the Owned Attributes section define the #appTheme attribute - to point to any desired name. This is the name that will show up in the - appearance section in settings.
-
-

Step 3. Define the theme's CSS

-

As a very simple example we will change the background color of the launcher - pane to a shade of blue.

-

To alter the different variables of the theme:

:root {
-	--launcher-pane-background-color: #0d6efd;
-}
-

Step 4. Activating the theme

-

Refresh the application (Ctrl+Shift+R is a good way to do so) and go to - settings. You should see the newly created theme:

-

- -

-

Afterwards the application will refresh itself with the new theme:

-

- -

-

Do note that the theme will be based off of the legacy theme. To override - that and base the theme on the new TriliumNext theme, see: Theme base (legacy vs. next) -

-

Step 5. Making changes

-

Simply go back to the note and change according to needs. To apply the - changes to the current window, press Ctrl+Shift+R to refresh.

-

It's a good idea to keep two windows, one for editing and the other one - for previewing the changes.

Customize the Next theme

- -
-

By default, any custom theme will be based on the legacy light theme. - To use the TriliumNext theme instead, add the #appThemeBase=next attribute - onto the existing theme. The appTheme attribute must also be - present.

-

- -

-

When appThemeBase is set to next it will use the - “TriliumNext (auto)” theme. Any other value is ignored and will use the - legacy white theme instead.

-

Overrides

-

Do note that the TriliumNext theme has a few more overrides than the legacy - theme, so you might need to suffix !important if the style changes - are not applied.

Detecting mobile vs. desktop

-

The mobile layout is different than the one on the desktop. Use body.mobile and body.desktop to - differentiate between them.

body.mobile #root-widget {
-	/* Do something on mobile */
-}
-
-body.desktop #root-widget {
-	/* Do something on desktop */
-}
-

Do note that there is also a “tablet mode” in the mobile layout. For that - particular case media queries are required:

@media (max-width: 991px) {
-
-    #launcher-pane {
-
-        /* Do something on mobile layout */
-
-    }
-
-}
-
-
-
-@media (min-width: 992px) {
-
-    #launcher-pane {
-
-        /* Do something on mobile tablet + desktop layout */
-
-    }
-
-}
-

Detecting horizontal vs. vertical layout

-

The user can select between vertical layout (the classical one, where - the launcher bar is on the left) and a horizontal layout (where the launcher - bar is on the top and tabs are full-width).

-

Different styles can be applied by using classes at body level:

body.layout-vertical #left-pane {
-	/* Do something */
-}
-
-body.layout-horizontal #center-pane {
-	/* Do something else */	
-}
-

The two different layouts use different containers (but they are present - in the DOM regardless of the user's choice), for example #horizontal-main-container and #vertical-main-container can - be used to customize the background of the content section.

-

Detecting platform (Windows, macOS) or Electron

-

It is possible to add particular styles that only apply to a given platform - by using the classes in body:

-
- - - - - - - - - - - - - -
WindowsmacOS
body.platform-win32 {
-	background: red;
-}
- 
body.platform-darwin {
-	background: red;
-}
-
-
-

It is also possible to only apply a style if running under Electron (desktop - application):

body.electron {
-	background: blue;
-}
-

Native title bar

-

It's possible to detect if the user has selected the native title bar - or the custom title bar by querying against body:

body.electron.native-titlebar {
-	/* Do something */
-}
-
-body.electron:not(.native-titlebar) {
-	/* Do something else */
-}
-

Native window buttons

-

When running under Electron with native title bar off, a feature was introduced - to use the platform-specific window buttons such as the semaphore on macOS.

-

See Native title bar buttons by eliandoran · Pull Request #702 · TriliumNext/Notes for - the original implementation of this feature, including screenshots.

-

On Windows

-

The colors of the native window button area can be adjusted using a RGB - hex color:

body {
-	--native-titlebar-foreground: #ffffff;
-	--native-titlebar-background: #ff0000;
-}
-

It is also possible to use transparency at the cost of reduced hover colors - using a RGBA hex color:

body {
-	--native-titlebar-background: #ff0000aa;
-}
-

Note that the value is read when the window is initialized and then it - is refreshed only when the user changes their light/dark mode preference.

-

On macOS

-

On macOS the semaphore window buttons are enabled by default when the - native title bar is disabled. The offset of the buttons can be adjusted - using:

body {
-    --native-titlebar-darwin-x-offset: 12;
-    --native-titlebar-darwin-y-offset: 14 !important;
-}
-

Background/transparency effects on Windows (Mica)

-

Windows 11 offers a special background/transparency effect called Mica, - which can be enabled by themes by setting the --background-material variable - at body level:

body.electron.platform-win32 {
-	--background-material: tabbed; 
-}
-

The value can be either tabbed (especially useful for the horizontal - layout) or mica (ideal for the vertical layout).

-

Do note that the Mica effect is applied at body level and the - theme needs to make the entire hierarchy (semi-)transparent in order for - it to be visible. Use the TrilumNext theme as an inspiration.

-

Note icons, tab workspace accent color

-

Theme capabilities are small adjustments done through CSS variables that - can affect the layout or the visual aspect of the application.

-

In the tab bar, to display the icons of notes instead of the icon of the - workspace:

:root {
-	--tab-note-icons: true;
-}
-

When a workspace is hoisted for a given tab, it is possible to get the - background color of that workspace, for example to apply a small strip - on the tab instead of the whole background color:

.note-tab .note-tab-wrapper {
-    --tab-background-color: initial !important;
-}
-
-.note-tab .note-tab-wrapper::after {
-    content: "";
-    position: absolute;
-    top: 0;
-    left: 0;
-    right: 0;
-    height: 3px;
-    background-color: var(--workspace-tab-background-color);
-}
-

Custom fonts

-

Currently the only way to include a custom font is to use Custom resource providers. - Basically import a font into Trilium and assign it #customResourceProvider=fonts/myfont.ttf and - then import the font in CSS via /custom/fonts/myfont.ttf.

-

Dark and light themes

-

A light theme needs to have the following CSS:

:root {
-	--theme-style: light;
-}
-

if the theme is dark, then --theme-style needs to be dark.

-

If the theme is auto (e.g. supports both light or dark based on prefers-color-scheme) - it must also declare (in addition to setting --theme-style to - either light or dark):

:root {
-
-    --theme-style-auto: true;
-
-}
-

This will affect the behavior of the Electron application by informing - the operating system of the color preference (e.g. background effects will - appear correct on Windows).
