title: Live Editing Zen Theme
|
|
---
|
|
|
|
This [[guides/index|guide]] will help you customize the appearance of Zen Browser by live editing the `userChrome.css` file. Follow the steps below to start customizing your browser's theme.
|
|
|
|
## Step 1: Access the Profile Folder
|
|
|
|
1. Open Zen Browser.
|
|
2. Type `about:support` in the address bar and press Enter.
|
|
3. Look for the **Application Basics** section.
|
|
4. Click on **Open Profile Folder**. This will open the folder where Zen Browser stores your user data.
|
|
|
|
## Step 2: Create the `chrome` Folder
|
|
|
|
1. In the Profile Folder, create a new folder and name it `chrome`.
|
|
2. Inside the `chrome` folder, create a new blank file named `userChrome.css`.
|
|
|
|
## Step 3: Open Style Editor in Zen Browser
|
|
|
|
1. In Zen Browser, press `Ctrl + Shift + Alt + I` to open the Developer Tools.
|
|
2. Navigate to the **Style Editor** tab.
|
|
3. In the filter/search bar, type `userChrome` to locate the `userChrome.css` file you created earlier.
|
|
|
|
## Step 4: Edit the `userChrome.css` File
|
|
|
|
1. The `userChrome.css` file should now be visible in the Style Editor.
|
|
2. You can start editing the file directly within the Style Editor.
|
|
- **Note:** You can use the **Inspect** button ![[inspect.png]] to hover over and select elements on the page. This allows you to learn about the `id`, `class`, or other attributes of elements, which you can then target in your `userChrome.css` file.
|
|
1. To apply your changes, save the file by clicking **Save** or by pressing `Ctrl + S`.
|
|
|
|
> [!tip]
|
|
> If a style does not apply as expected, try adding the `!important` keyword at the end of the CSS rule. This forces the browser to apply the style regardless of any other existing styles.
|
|
|
|
> [!Notes]
|
|
>Any changes you make to the `userChrome.css` file will be applied immediately to Zen Browser.
|
|
>Use this file to customize various UI elements, such as colors, fonts, and layout.
|
|
>You can use this guide to help you [[themes-marketplace| create your Zen theme and publish it.]]
