<p>Sınıf <code>(<em>class</em>)</code> seçicisi, bir HTML belgesindeki elementin <font face="Consolas, Liberation Mono, Courier, monospace">{{htmlattrxref("class")}} </font>özniteliğinin içeriği ile eşleşir. <font face="Consolas, Liberation Mono, Courier, monospace">{{htmlattrxref("class")}} özniteliği boşlukla ayrılmış değerler listesi olarak tanımlanabilir, bu durumda stil ataması yapılabilmesi için seçicinin özniteliğe verilen değerlerden biri ile birebir eşleşmesi gerekir.</font></p>
