Issue with CSS styling not being reflected in JSF application

I am currently diving into the world of JSF and facing an issue with moving my inline styles to a CSS file. Despite my efforts, I can't seem to get it to work as expected. Below is the code snippet for reference.

The location of my XHTML file is as follows:
\WebContent\template\

And the CSS file resides here:
\WebContent\resources\css\

Here is a snippet of the XHTML code:

<ui:composition template="/template/BasicTemplate.xhtml">
<h:outputStylesheet library="css" name="style.css" />
    <ui:define name="content">
        <h:form>
       dfdskdksdk <h:outputText value="#{msg['message.test1']}" />
<table width="80%">
    <tr>
    <h:outputStylesheet library="css" name="css/style.css" />
        <td width="15%" background="red" >
            <b>Location Coverage*</b>
        </td>

I have experimented with different combinations like:

<h:outputStylesheet library="css" name="css/style.css" />
<h:outputStylesheet library="css" name="style.css" />
<h:outputStylesheet library="css" name="/resources/css/style.css" />
<h:outputStylesheet library="css" name="resources/css/style.css" />

I've tried placing this line both inside and outside the <ui:composition> tag but still no luck.

Any insights or solutions would be greatly appreciated!

Answer №1

The error you made is with the positioning of the <h:outputStylesheet>:

<ui:composition template="/template/BasicTemplate.xhtml">
    <h:outputStylesheet library="css" name="style.css" />
    <ui:define name="content">
        ...
    </ui:define>
</ui:composition>

When designing a template client, it's crucial to note that anything outside of <ui:define> is disregarded (similarly to anything outside <ui:composition>).

To correct this issue, move the declaration of <h:outputStylesheet> inside <ui:define>:

<ui:composition template="/template/BasicTemplate.xhtml">
    <ui:define name="content">
        <h:outputStylesheet library="css" name="style.css" />
        ...
    </ui:define>
</ui:composition>

Furthermore, using "css" as your generic content type for the library name seems unusual. If you don't have a specific library, simply omit it:

        <h:outputStylesheet name="css/style.css" />
