This document provides instructions on how to fill in the CSS Selector fields during PageAssist setup.

Element selector

The element selector selects elements based on their element name. For example, to select all <p> elements on a page, use the selector:

p

CSS element > element Selector

Use the element > element selector to select elements with a specific parent.

ul > li 

ID selector

The ID selector uses the id attribute of an HTML element to select a specific element.

The ID of an element should be unique within a page, so the ID selector can be used to select one unique element.

To select an element with a specific ID, write a hash # character, followed by the ID of the element.

The style rule below is applied to the HTML element with id="para1"

 #para1

Class selector

The class selector selects elements with a specific class attribute.

To select elements with a specific class, write a period . character, followed by the name of the class.

In the example below, all HTML elements with class="center" are selected using this selector:

 .center

It is also possible to indicate that only specific HTML elements should be affected by a class.

The example below indicates only <p> elements with class="center" use the selector:

 p.center

HTML elements can also refer to more than one class.

In the example below, the <p> element is selected with both center and large as classes class="center large" . Use this selector:

 p.center.large

CSS :nth-child() selector

The :nth-child(n) selector matches every element that is the nth child, regardless of its parent type. n can be a number, a keyword, or a formula. In this example, is will typically be set to match by number.

The selector below will select the 2nd p element in this example:

<p>Paragraph 1</p>
<p>Paragraph 2</p> 
<p>Paragraph 3</p> 

Selector:

 p:nth-child(2)

CSS :mon-parent selector

Takes the parent element of the selected element.

Custom selectors

We have created a series of custom CSS selectors that do NOT exist in normal CSS and only in the PageAssist system.

CSS :mon-next selector

Allows you to select the next element on the same level.
