At this point you have all the portlets you want on your page and you've created and logged in with your own user. For security, delete the test user that you logged in with in the previous section. To delete the test user, click on the Users tab in Enterprise Admin portlet and search for the test user. Click on the Delete icon.
You can now change the look and feel of your portal. Liferay Portal comes pre-bundled with different themes that you can apply to your page.
Changing the Theme
Click on the Page Settings link at the top of your page.
Select the page you would like to theme on the left hand side. Note that by default all children pages will inherit the theme from the parent.
Now select the Look and Feel tab for that page.
You will see a number of bundled themes that are available with Liferay Portal. Choose your theme and color scheme. You can experiment with it as much as you like until you find a theme that pleases you. Don't spend too much time here now... time to move on...
NOTE: Although Liferay comes with many bundled themes, there are also a vast number of themes contributed to Liferay Portal from the community. You can view these on our website or develop your own custom theme for your company or application. Please read the Building Themes chapter in the Liferay Portal Developers Guide.
