Basic Syntax

[element identifer] {
attribute:value;
attribute2:value;
}
The element identifier can be anything from a simple element type/class/element id to a complex specification detailing element structures within the DOM to which the xstyle should be applied. See below for details.

Simple Element Identifiers

<element> Element such a p or h1
.<class> All elements with the given class-name
#<id name> Applies only to the element with the given Id. Note: Element Ids should be unique

Complex Element Identifiers

<element> .<class> Only those elements with the given class. This is probably the most common form of identifier
<element >.<class>, <element> .<class> Applies to both sets of identifiers
<element> [Attribute] Applies only <element> with the given attribute. The ‘[‘ are required
div > p All p elements one level deep in div
div + p p elements immeidately after div tag
div * All elements within a div

Selectors

The following selectors can be used in combination with any of the above identifiers to further narrow down the set of target elements

:root All elements at document root level.
:first-child Refers to the first child element of <element>
:last-child Refers to the first child element of <element>
:nth-child(2) Refers to the second (n=2) child element of <element>
