Distinction between style and styleClass on a JSF webpage

I recently began navigating a java code base that utilizes the style and styleClass keywords to customize elements within the jsf page. This particular project is built on jsf 2.2.

The 'style' keyword is used for applying html attributes like:

<h:panelGroup style="margin-top:60px">
</h:panelGroup>

On the other hand, the 'styleClass' keyword is employed to incorporate classes/styles from the .css file such as:

<h:panelGroup layout="block" styleClass="panel panel-default">    
</h:panelGroup>

This leads me to ponder whether there exists a specific guideline for when each keyword should be used, or if it's simply a matter of personal preference in this scenario. Upon referencing this link, I fail to discern any noticeable disparity between the two keywords.

Answer №1

Attributes play a crucial role in defining the style of a component. The styleClass attribute adds CSS classes to the component, while the style attribute defines inline style properties for that specific element.

For example:

<h:panelGroup style="margin-top:60px">
</h:panelGroup>

Would result in the following HTML:

<span style="margin-top: 60px"></span>

It's important to note that it generates a span element as panelGroup defaults to rendering a span.

On the other hand,

<h:panelGroup layout="block" styleClass="panel panel-default">    
</h:panelGroup>

Would generate:

<div class="panel panel-default"></div>

This knowledge is fundamental in HTML and doesn't have much association with JSF, besides the names like style and styleClass.
