Working with Themes in the AWS Cloud9 Integrated Development Environment (IDE)

A theme defines your overall IDE colors. This applies across each AWS Cloud9 development environment associated with your IAM user. As you make changes to your theme, AWS Cloud9 pushes those changes to the cloud, and associates them with your IAM user. AWS Cloud9 also continually scans the cloud for changes to the theme associated with your IAM user, and applies those changes to your current environment.

You can share any custom theme overrides you define with other users.

View or Change Your Theme

1. On the menu bar, choose AWS Cloud9, Preferences.

2. To view your theme across each environment of yours, on the Preferences tab, in the side navigation pane, choose Themes.

3. To change your theme across each environment of yours, in the Themes pane, change the settings you want. To change portions of your theme by using code, choose the your stylesheet link.

4. To apply your changes to any environment of yours, simply open that environment. If that environment is already open, refresh the web browser tab for that environment.

Overall Theme Settings You Can Change

You can change the following kinds of overall theme settings on the Preferences tab in the Themes pane.

Flat Theme

Applies the built-in flat theme across the AWS Cloud9 IDE.

Classic Theme

Applies the selected built-in classic theme across the AWS Cloud9 IDE.

Syntax Theme

Applies the selected theme to code files across the AWS Cloud9 IDE.

Theme Overrides You Can Define with Code

You can override portions of the overall theme in the AWS Cloud9 IDE. These overrides will persist even if you change the overall theme itself in the AWS Cloud9 IDE.

For example, let's say you want to change the background color of the titles on open tabs to yellow, regardless of the related setting for the current overall theme that is currently applied to the AWS Cloud9 IDE.

First, use your web browser's developer tools to determine the CSS class for the portion of the theme you want to change. For example, do the following for Google Chrome.

1. Choose Customize and control Google Chrome, More tools, Developer tools.

2. In the Developer tools pane, choose Select an element in the page to inspect it.

3. Pause your mouse over the portion of the IDE you want to change. In this example, pause your mouse over the title of an open tab.

4. Note the CSS class name. In this example, the CSS class name for the title of an open tab is sessiontab_title.

Next, add a corresponding CSS class selector to your styles.css file.

1. On the menu bar, choose AWS Cloud9, Preferences. In the side navigation pane, choose Themes. Then choose the your stylesheet link.

2. In the styles.css file, add the CSS class selector. In this example, you use the .sessiontab_title selector to set background-color to yellow.

   .sessiontab_title {
     background-color: yellow;
   }

Finally, save the styles.css file, and note the change to the theme. In this example, the background color of the titles of open tabs changes to yellow. Even if you change the overall theme in the AWS Cloud9 IDE, the CSS overrides in your styles.css file persist.

Note

To revert this theme override, remove the preceding code from the styles.css file, and then save the file again.

Share Your Theme Overrides with Another User

1. In both the source and target environment, on the menu bar of the AWS Cloud9 IDE, choose AWS Cloud9, Open Your Stylesheet.

2. In the source environment, copy the contents of the styles.css tab that is displayed.

3. In the target environment, overwrite the contents of the styles.css tab with the copied contents from the source environment.

4. In the target environment, save the styles.css tab.
