I’m entering the JSF world and I’m trying to create a calculator but I’m not getting to leave the buttons out of space, they need to be together, someone knows how I fix this?

    <h:form>
            <h:panelGrid columns="4">
                <h:commandButton value="7" />
                <h:commandButton value="8" />
                <h:commandButton value="9" />
                <h:commandButton value="/" />
            </h:panelGrid>
        </h:form>

Use the attributes cellpadding and cellspacing to remove spaces between cells:

<h:panelGrid columns="4" cellpadding="0" cellspacing="0">
        <h:commandButton value="7" />
        <h:commandButton value="8" />
        <h:commandButton value="9" />
        <h:commandButton value="/" />
</h:panelGrid>

  • Still shows the spaces.

  • Make sure you don’t have any css of your own by interfering with panelGrid css
