Olá pessoal.
Não estou conseguindo aplicar o @media para fazer o ajuste do tamanho das fontes a partir de 650px de width. Seguem meus códigos:
<!-- aluraconf/index.html -->
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>AluraConf</title>
<link rel="stylesheet" href="css/reset.css">
<link rel="stylesheet" href="css/header.css">
</head>
<body>
<div class="contain">
<header class="header">
<nav class="main-menu">
<ul class="itens-menu">
<li>
<a href="#">About</a>
</li>
<li>
<a href="#">Speakers</a>
</li>
</ul>
</nav>
<div class="jumbotron">
<section>
<h1 class="tittle">WEB SUBMMIT CONF</h1>
<h2 class="subtittle">22 november | Lisboa </h2>
</section>
<section>
<h3><a class="botao-inscrever" href="#">Subscribe</a></h3>
</section>
</div>
</header>
</div>
</body>
</html>.header .main-menu .itens-menu{
text-transform: uppercase;
text-align: center;
}
.itens-menu li{
display: inline-block;
padding: 20px;
background-color: rgba(0, 0, 0, 0.1);
margin: 20px 5px;
border-radius: 5px;
transition: background-color: 0.5s;
}
.itens-menu li:hover{
background-color: #48A3A6;
}
.itens-menu a{

text-decoration: none;
}
.header{
background: url('../img/destaque.jpeg') no-repeat ;
background-size: cover;
}
.jumbotron{
text-align: center;
margin: 20px;
}
.jumbotron h1, h2{
margin: 3px;
font-family: sans-serif;
font-weight: bold;
text-shadow: 4px 4px 10px #000;
}
.jumbotron .tittle{
font-size: 3em;
color: #fff;
}
.jumbotron .subtittle{
font-size: 2.6em;
color: #77f76d;
}
.jumbotron .botao-inscrever{
background-color: rgb(72, 163, 166);
border-radius: 5px;
padding: 25px 50px;
color: rgb(255, 255, 255);
text-decoration: none;
text-transform: uppercase;
display: inline-block;
margin-top: 30px;
margin-bottom: 50px;
font-size: 2em;
}
@media(min-width: 650px) {
.header .jumbotron{
font-size: 28px;
}
}Muito agradecido.
