Introduction

Defining

The Attribute in the Attributes App Inspector tab or Attributes Dialog is CSS Style.
The name for use with setAttribute() and getAttribute() is cssStyle.
Using Lianja.get(), the property is stylesheet or css.
For custom coding using the Lianja UI Framework the property is stylesheet or css.

The attribute/property can be set to the name of a CSS file.

Use the 'app:/' prefix for a CSS file in the App:

app:/myapp.css

and the 'lib:/' prefix for a CSS file in the library.

lib:/myapp.css

Alternatively, it can be set to a character string. Each property definition is terminated with a semi-colon (;):

border: 2px solid green; font: bold italic large "Times New Roman";

Note: as well as the primary CSS Style attribute the following can also be defined:

Page:

Navigation Panel: CSS Style (leftSidebarTreeStylesheet)

Section:

Header: Header CSS Style (headerCssStyle)
Subtitle: CSS Style (subtitleCssStyle)
Footer: Footer button CSS (footerButtonCss)

Checklistview Gadget:

Listview Gadget:

Selectors

Selectors define the individual object or type of object to be styled.

Universal Selector

The asterisk (*) selects all objects.

ID Selectors

The ID selector for a named object is #id.

Note: this corresponds to the Name attribute in the Attributes App Inspector tab or Attributes Dialog.

Each UI element is given a unique object id.

Page is the pageid.

Section is pageid + "_" + sectionid

Formitem is pageid + "_" + sectionid + "_" + formitemid;

e.g.

#page1_section1_field1

Note: a 'formitem' can be a Form Section Field or Gadget or a Canvas Section Advanced Control.

In Custom Sections, the elements use the "name" property that you assign to them.
