Site Appearance

You can customize the design and functionality of a Liferay site in several different ways. The table below shows the Liferay tools you can use:

FeaturesStyle BooksMaster Page TemplatesThemes
Embed common fragments/widgets
Define common layouts for pages
Managed through the UI
Customize styles, spacing, colors, etc.
Add extra functionality

Master Page Templates

With Master Page Templates, you can define common elements for your pages using fragments, especially headers and footers. Use them to conform any number of pages on your site to the look and feel you design.

Master Page Templates are a simple way to define elements common to all of your pages, such as headers and footers.

Style Books

Style Books are visual standards defined for a site, such as standard colors and spacing. With Style Books, you can design every page’s layout independently while maintaining a consistent experience between each of them.

Style Books define the rules for your Site's appearance, such as text colors.

Widget/Fragment Appearance

Fragments and widgets are the building blocks of your site. There are many ways to customize them to suit your site’s appearance.

  • Fragment customizations can be used to tailor the look and feel of your site’s fragment pages.

  • Application Display Templates can customize the appearance and behavior of the widgets on your site.

Themes

Themes are a frontend developer’s tool for customizing the default look and feel of your site. They provide a foundation that your Style Books and Page Templates can extend. You can also embed widgets in a theme to ensure a particular arrangement.

Note

Themes are not supported in Liferay SaaS.

Choosing a theme for your site's pages can significantly alter your site's look and feel.
