Changing Your Site’s Appearance

Liferay has many ways to customize your site’s appearance. Your site’s favicon and theme are two of the first elements you may want to change. Themes set a default look and feel for your site, while the favicon is an icon that identifies your site in the user’s browser tab.

Changing Your Site’s Favicon

Start a new Liferay instance by running

docker run -it -m 8g -p 8080:8080

Sign in to Liferay at http://localhost:8080. Use the email address test@liferay.com and the password test. When prompted, change the password to learn.

Then, follow these steps:

  1. Open the Site Menu (Site Menu) and navigate to Site Builder → Pages.

  2. Click Actions (Action button) in the Application Bar and select Configuration.

    Open the Pages application, click Actions in the Application Bar, and select Configuration.

  3. Under Favicon, click Select Favicon (Select Favicon button).

    Click the Select Favicon button.

  4. Select or upload an image.

  5. Click Save.

Your site uses the chosen image for its favicon.

Changing Your Site’s Theme

By default, Liferay instances use the Classic theme, but you can deploy and use custom themes.

Deploy a New Theme

  1. Download and unzip the Acme Sample Blue Theme WAR file:

    curl https://resources.learn.liferay.com/dxp/latest/en/getting-started/changing-your-sites-appearance/resources/liferay-5b2v.zip -O

    unzip liferay-5b2v.zip

  2. Go to the folder where the .war file is placed and deploy it:

    docker cp liferay-5b2v-theme.war [docker-container-id]:[path-to-deploy-folder]
Note

To replace [docker-container-id], use docker ps to find the liferay/portal container’s ID. The [path-to-deploy-folder] is opt/liferay/deploy.

This loads the sample theme into your DXP instance. You can check your console for the following message to confirm the theme successfully deployed:

2023-12-21 16:01:20.836 INFO  [fileinstall-directory-watcher][BundleStartStopLogger:68] STARTED liferay-5b2v-theme_1.0.0 [1617]

Change Your Site’s Theme

  1. Open the Site Menu (Site Menu) and navigate to Site Builder → Pages.

  2. Click Actions (Action button) in the Application Bar and select Configuration.

    Open the Pages screen, click Actions in the Application Bar, and select Configuration.

  3. Under Theme, click Change Current Theme:

    Click Change Current Theme to select a new theme.

  4. Select the sample theme: Acme Sample Blue Theme.

  5. Click Save.

Navigate to the Home page and confirm the background color is now blue.

Confirm the background color is now blue.

What’s Next

Additionally, you can use style books to further customize design elements and master page templates to design the header and footer for content pages. See Site Appearance for a complete overview of customizing the look and feel of your site.

There are many themes available on the Liferay Marketplace that can be used to quickly achieve a professional look and feel.

You can also learn how to create your own theme.
