<h3 id="Resumo" name="Resumo">Resumo</h3>
<p>A largura da borda esquerda de um elemento em pixels inclui a largura da barra de rolagem vertical se a direção do texto do elemento estiver da direita para a esquerda e se houver um excesso causando uma barra de rolagem vertical na esquerda para ser renderizada. <code>clientLeft</code> não inclui a margem ou o enchimento esquerdo. <code>clientLeft</code> é somente leitura.</p>
<p>Aplicações baseadas em <a href="pt/Gecko">Gecko</a> suportam <code>clientLeft</code> començando com o Gecko 1.9 (<a href="pt/Firefox_3_para_desenvolvedores">Firefox 3</a>, implementado em {{ Bug(111207) }}). Esta propriedade não é suportada pelo Firefox 2 e mais antigos.</p>

  <p>Gentle, individualistic and very loyal, Birman cats fall between Siamese and Persian in character. If you admire cats that are non aggressive, that enjoy being with humans and tend to be on the quiet side, you may well find that Birman cats are just the felines for you.</p>
  <p><span style="float: right;"><img alt="Image:BirmanCat.jpg"></span>All Birmans have colorpointed features, dark coloration of the face, ears, legs and tail.</p>
