What you need to get started

  • A completed Ceros experience

  • A Transifex account

  • SDK access for your Ceros account (only for custom language pickers)

If you aren’t already a Transifex customer, sign up for a 30-day free trial with the link here and let your Ceros account manager know you’re interested in localization!

Getting Started

Step 1: Create a new Transifex project

  1. Log into your Transifex account and click Create new project.

  2. Set the project type as Live.

  3. Choose the experience’s source languages and the ones you want to translate into.

  4. Click Create Project.

  5. Under What can I do now?, type https://view.ceros.com (or your vanity URL if you’re using one) into the text box and click Create Resource.

  6. In the top right corner, click the three dots and then Settings.

  7. In the Staging domain field, enter the domain of your preview links (https://account-name.preview.ceros.com). If you aren’t sure, open up an experience in Studio and click Preview.

  8. Note the Live API Key for the next step.

  9. Click Save Settings.

Step 2: Add the Transifex plugin to your Ceros experience

1. In Studio, open up the experience you want to translate.

2. Click Settings and then the Custom HTML tab.

3. Paste the following code in:

<script type="text/javascript">
window.liveSettings = {
dynamic: true,
detectlang: true
<script type="text/javascript" src="//cdn.transifex.com/live.js"></script>
<script type="text/javascript" src="//sdk.ceros.com/standalone-player-sdk-v5.min.js"></script>
<script type="text/javascript" src="//creative-services.ceros.com/ceros/transifex-plugin/0.0.1/ceros-transifex-plugin.min.js"></script>

4. In line 3 of the code you just pasted, replace INSERT_TRANSIFEX_LIVE_API_KEY_HERE with the API key from the previous step.

5. In line 5 of the code, you’ll find the detectlang option. This can have multiple settings:

  • true - the page will be displayed in the user’s language if available (based on browser/OS language) otherwise, the source language

  • false - the page will always be displayed in the source language first

  • function() { return 'LANG'} - the page will always be displayed first in the language specified. Replace LANG with the desired language code.

6. Click OK.

Step 3: Mark Strings that should be translated

  1. In Studio, click Preview.

  2. Click on the address bar and add ?Transifex to the end of the URL. It should look something like this:


  3. The Transifex sidebar should open. Click Log in and use your Transifex credentials.

  4. Click through all of the different parts of the experience to let Transifex discover all of the text. Make sure to scroll to the bottom of each page, and if there are pop-ups, make sure to click through those as well.

  5. Once you’re done, click Manage Strings. Scroll through the list and click the checkbox next to any text that should be translated. If you aren’t sure, don’t select it (you can always select it later).

  6. Click Approve.

  7. Close the Manage Strings box and quickly scroll through the experience again. All of the text boxes should now appear green. If you see any that are still in blue, go back to Manage Strings and make sure you got them all.

Step 4: Translate the strings

  1. In the Transifex resource page for https://view.ceros.com, click the blue arrow and then Translate in Editor.

  2. Translate the text using your methodology of choice. If you have any questions about this process, contact your Transifex account executive. For demonstration purposes, you can select all of the words and click Machine Translate to get a rough idea of what the experience can look like.

Step 5: See what the translations look like in the experience

  1. Go back to the Preview window and reload the page. If the Transifex sidebar doesn’t appear, add ?Transifex to the end of the URL.

  2. In the Transifex sidebar, click the languages dropdown and select one of the languages that have been translated. The text should change.

  3. Observe any areas in the design that appear broken in a different language (text overflowing to a new line, extending too far into another part of the experience).

  4. In the Studio, adjust the size of the relevant textboxes, font size, etc. The results should be reflected immediately in the Preview window.

Step 6: Publish translations

  1. Click Publish in the Transifex sidebar.

  2. Select all of the languages, and click Publish.

  3. Click the Production tab and repeat the previous step.

Embedding the experience

To embed a localized experience in your website, you’ll need to slightly modify the embed code to show each language.

For example, here’s the relevant part of the embed code that you get from the Studio publish dialog box:

<iframe allowfullscreen src='//view.ceros.com/internal-ryan-hefner/together-demo-2?heightOverride=3412&mobileHeightOverride=7373' 

To force this embed to display in Spanish, add &lang=es to the end of the URL. All other parts of the code should remain the same. Here’s what it should look like:

<iframe allowfullscreen src='//view.ceros.com/internal-ryan-hefner/together-demo-2?heightOverride=3412&mobileHeightOverride=7373&lang=es'

Create a language picker

If your experience is embedded in a website that’s already localized, it probably doesn’t need a language picker (see above for embed instructions). If you need a picker, you have two options - use the basic language picker provided by Transifex or create one from scratch with native Ceros Studio components.

Enable the basic Transifex language picker

  1. In the Transifex sidebar, click Settings, and under the Language picker position, choose a location.

  2. Click Save.

Create a language picker using Ceros Studio components

  1. In the Transifex sidebar, click Settings and under Language picker position, and either choose a location (for Transifex’s picker) or Do not place a picker (for a custom picker).

  2. Click Save.

  3. Switch to the Production tab and repeat.

  4. Click Log out and then click the X to close the sidebar.

  5. If you’re using the Transifex language picker, stop here.

  6. In Studio, create a language picker in any way you desire (contact your Ceros account executive if you’d like to see some examples). The only requirement is that there will be a separate hotspot per language variant.

  7. Open the SDKPanel.

  8. For each language variant hotspot, add the tag language-select and set the payload to the language code from Transifex. For example, the code for English is en, and for Spanish is es. Also, click the Active cursor on hover checkbox.

Create language-specific images

Ceros experiences often contain language-specific components. For example, you might have an image that contains text that needs to be displayed in the correct language.

  1. Create all language versions of the component and drag them into Studio as layers.

  2. Create the folder structure as shown in this image (parent folder → language-specific subfolders → language-specific content).


  3. Open the Ceros SDK tab. Click the parent folder (image in the example above) and enter the tag language-swap.

  4. Click each language-specific subfolder (en, es, and ja in the example above) and enter the language code as the payload (again en, es, and ja respectively).

  5. Open the Ceros preview and switch between languages to ensure everything looks right.
