+## Styling
+
+By default the Web OC loads the `weboc-default-style.css` which can be found in the root directory of a Web OC build.
+Three more style sheets with font specification, chart styles and specific css overruling Vuetify component styles are imported by this file.
+In the following section a number of css variables define a number of colors used by the Web OC in normal (light) and dark mode.
+
+```css
+@import './fonts/exo-2/fonts.css';
+@import './default-styles.css';
+@import './vuetify-overrule.css';
+
+:root {
+ --font-family: 'Exo 2', sans-serif;
+ --theme-color: white;
+ --contrast-color: black;
+ --canvas-fill: rgb(223, 223, 223);
+ --weboc-app-bar-bg-color: #080c80;
+}
+
+.dark {
+ --contrast-color: rgb(255, 255, 255);
+ --theme-color: black;
+ --canvas-fill: rgb(54, 54, 54);
+}
+```
+
+Create a copy of the `weboc-default-style.css` and change the line in the `WebOperatorClient.xml` file to point to the new file:
+```xml
+weboc-default-style.css
+```
+See [Web OC Delft-FEWS configuration ](configuration/) for more information on the `WebOperatorClient.xml` file.
+
+### Changing the WebOC colors
+
+Change the following css variable to change the colors used in light or dark mode:
+
+| Variable | Description |
+| --- | ---- |
+| `--weboc-app-bar-bg-color` | Color of app top menu bar |
+| `--theme-color` | Color of texts and chart axes |
+| `--contrast-color` | Contrast color used in charts |
+| `--canvas-fill` | Chart canvas background color |
+
+### Changing the WebOC fonts
+
+It is easy to host your own set of [web fonts](https://developer.mozilla.org/en-US/docs/Learn/CSS/Styling_text/Web_fonts) or use a service like Google fonts https://fonts.google.com/.
+
+To use a font from the Google font service — check license conditions — replace the first import (`@import './fonts/exo-2/fonts.css';`) with the import statement for including the selected font. Take the import statement from the "Web @import" tab at https://fonts.google.com/selection/embed after selecting a font.
+
+As an example, the following import make the Dancing Script fonts available
+
+```css
+@import url('https://fonts.googleapis.com/css2?family=Dancing+Script:wght@400..700&display=swap')
+```
+
+Then change the `--font-family` variable to read
+```css
+:root {
+ --font-family: 'Dancing Script', sans-serif;
+ ...
+}
+```
+The correct name of the font can also be found at https://fonts.google.com/selection/embed.
+
+
+
+> [!TIP]
+> Using a font service might require changes to the `font-src` and `style-src` Content Security Policy in the webserver configuration.
+
+Self hosting of web fonts requires fonts in a `woff` or `woff2` format.

Although Web OC will run without any further adjustments to the Delft-FEWS configuration, its strongly recommended to spend some time on your Topology configuration in relation to Web OC (see below).
-### System time
+> **_NOTE:_** Please note that Web OC will always use the system time of the Web OC users device as Web OC system time. This time setting can not be modified by Web OC configuration.
+

+^ **NOTE**: The FEWS PI webservices (2023.02) can be used to serve [static web resources](https://fewsdocs.deltares.nl/webservices/rest-api/v1/#get-/resources/static/-path-/-id-).
+Relative urls in `WebOperatorClient.xml` are first resolved against the base url of the Web OC instance (e.g. `deltares_logo.png`), and then against the resources endpoint of the FewsWebServices instance.
+
+### Styling
+
+With the customStyleSheet option in the `WebOperatorClient.xml` , it is possible to load a custom stylesheet for Web OC. This stylesheet will be loaded after the default stylesheet and can be used to override default styles. The custom stylesheet should be placed in the same directory as the index.html file.
+
+```css
+@import '../fonts/exo-2/fonts.css';
+@import './default-styles.css';
+@import './vuetifiy-overrule.css';
