Question

I’m looking for a solution of adding a value for a style property of an xhtml page component.
It could be control or HTML element both cases suits me fine.

Here’s an example of the idea

<ctrl:ctrlName ..... style="The_Parameter" />

or

<div ..... style="The_Parameter" />

If someone happens the be familiar with this or any technique that could help, I do appreciate your kind help, BR

You can just use an EL expression referencing a bean property in the style attribute of a JSF component and even a plain vanilla HTML element.

E.g.

<h:panelGroup layout="block" style="#{bean.style}">...</h:panelGroup>
<div style="#{bean.style}">...</div>

with

private String style;

@PostConstruct
public void init() {
    style = "background: pink;"; // Or something dynamic.
}

public String getStyle() {
    return style;
}

I’d only prefer styleClass resp. class over style by the way. Separate style from markup (and model).
