+<p><span class="seoSummary">A interface <strong><code>Document</code></strong> representa qualquer página da <em>Web </em>carregada no navegador e serve como um ponto de entrada para um conteúdo da página da <em>Web</em>, que é <a href="/pt-PT/docs/Using_the_W3C_DOM_Level_1_Core" title="Using_the_W3C_DOM_Level_1_Core">árvore DOM</a>.</span> A árvore DOM inclui elementos, tais como {{HTMLElement("body")}} e {{HTMLElement("table")}}, entre <a href="/pt-PT/docs/Web/HTML/Elemento">muitos outros</a>. Este fornece funcionalidade globalmente para o documento, tal como obter o URL da página e criar novos elementos no documento.</p>

+
+<p>The <code>Document</code> interface describes the common properties and methods for any kind of document. Depending on the document's type (e.g. <a href="/en-US/docs/HTML" title="HTML">HTML</a>, <a href="/en-US/docs/XML" title="XML">XML</a>, SVG, …), a larger API is available: HTML documents, served with the <code>text/html</code> content type, also implement the {{domxref("HTMLDocument")}} interface, whereas XML and SVG documents implement the {{domxref("XMLDocument")}} interface.</p>

Se não há elementos que correspondem, <code>null</code> é devolvido como resultado.</p>
+

+<p><strong>Nota</strong>: A correspondência é feita através de uma travessia <em>pre-order</em> em profundidade dos nódulos do documento, a começar com o primeiro elemento da marcação do documento e iterando através de nódulos sequenciais por ordem do número de nódulos filhos.</p>

+ <dd>Um {{domxref("DOMString")}} a conter um ou mais seletores para com que corresponder. Esta string tem de ser um seletor de CSS valido; se não é, uma <em>exception</em> <code>SYNTAX_ERR</code> é lançada.

+<p><strong>Nota:</strong> Os carateres que não fazem parte da sintaxe padrão do CSS devem ser evitados ao usar um caráter de barra invertida.

+
+<p>Para corresponder a um ID ou seletor que não segue a sintaxe de CSS padrão (ao usar o caráter de dois pontos ou espaço incorretamente), deve escapar o caráter com uma barra invertida ("<code>\</code>"). Como a barra invertida também é um caráter de escapar no JavaScript, se a escrever numa <em>string literal</em>, tem de a escapar duas vezes (primeiro para a <em>string</em> do JavaScript, e depois para o <code>querySelector()</code>):</p>
+
+<pre class="brush: html notranslate">&lt;div id="foo\bar"&gt;&lt;/div&gt;
+&lt;div id="foo:bar"&gt;&lt;/div&gt;
+
+&lt;script&gt;
+  console.log('#foo\bar');               // "#fooar" (\b é o caráter de controlo para a barra invertida)

+
+  console.log('#foo\\bar');              // "#foo\bar"
+  console.log('#foo\\\\bar');            // "#foo\\bar"

+</pre>
+
+<h3 id="Um_seletor_mais_complexo">Um seletor mais complexo</h3>
+
+<p>Seletores são muito poderosos, como demonstrado no seguinte exemplo. O primeiro elemento {{HTMLElement("input")}} com o nome "login" (<code>&lt;input name="login"/&gt;</code>) encontrado dentro dum {{HTMLElement("div")}} cuja classe é "user-panel main" (<code>&lt;div class="user-panel main"&gt;</code>) no documento é devolvido:</p>
+
+<pre class="brush: js notranslate">var el = document.querySelector("div.user-panel.main input[name='login']");
+</pre>
+
+<h3 id="Negação">Negação</h3>
+
+<p>Todos os strings de seletores de CSS são válidos, assim também é possivel ter seletores de negação:</p>
+
+<pre class="brush: js notranslate">var el = document.querySelector("div.user-panel:not(.main) input[name='login']");</pre>
+
+<p>Isto seléciona um <code>input</code> que tem um <code>div</code> com classe <code>user-panel</code> como parente, mas sem a classe <code>main</code>.</p>
