Problems with CSS on an XHTML page

When starting my project I created all the favorable structure for the proper functioning of the CSS file.

This is my page;

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:p="http://primefaces.org/ui">

<h:head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

    <h:outputStylesheet library="css" name="sistema.css" />
</h:head>


<h:body>

    <div id="tudo">

        <div id="topo">
            <div id="fone">TELEFONE DE CONTATO 011-3847-9076</div>
        </div>
        <div id="menu">
        Agendadorhbjhbscjbdhcjhbsd

        </div>
        <div id="conteudo"></div>
        <div id="rodape"></div>

    </div>

</h:body>
</html>

Since this bit of code didn’t work;

    <div id="menu">
    Agendadorhbjhbscjbdhcjhbsd

    </div>

At first I thought it was the eclipse that was slow in replicating the change, so I cleared the project, stopped and started on Tomcat and pressed F5 on keyboard to update the web page, but I was unsuccessful and still generated an error message on the eclipse consoles;

Obviously I know the cause is because of "An established connection has been overridden by the software on the host computer"

belaza, no problem, the only problem is knowing how to solve, because I’ve never had a problem like this.

I accept suggestions.

======================================================================

See how the tag is

#menu{
    position:relative;
    height:90px;
    font-size: 32px;

    background: black;
    filter:alpha(opacity=27);
    -moz-opacity:.27;
    opacity:.27;
}

The problem is here;

background: black;
filter:alpha(opacity=27);
-moz-opacity:.27;
opacity:.27;

When I add these lines of code in CSS it causes things written not to appear.

Why does that happen? How do I fix it?

Try it this way. The fact that it doesn’t appear is that the menu text was the same as the background, when I switched to red it appeared. I don’t know how you get with the rest of your style, but running here appeared.

This will not make the server error disappear, but reinforcing the need to put the h:html tag.

#menu{

    position:relative;
    height:90px;
    font-size: 32px;
    color:red;
    background: black;
    filter:alpha(opacity=27);
    -moz-opacity:.27;
    opacity:.27;
}
