In the previous section, we discussed that theme engineers can add configurable custom settings in the
liferay-look-and-feel.xml file of a theme. Liferay portal can also include some predefined out-of-the-box settings such as
bullet-style-options in a theme to control certain default behavior of the theme.

portlet-setup-show-borders-default as an example to explain how Liferay portal controls the display of the portlet border at different levels.
If this predefined setting is set to
false in your theme, Liferay portal will turn off the borders for all portlets on all pages where this theme is applied to.
