¿Cuáles son las etiquetas obligatorias en XHTML?
Un documento XHTML debe tener una declaración DOCTYPE de XHTML. Una lista completa de todos los Doctypes de XHTML se encuentra en nuestra Referencia de Etiquetas HTML. Los elementos , , y
también deben estar presentes, y el atributo xmlns en <html> debe especificar el espacio de nombres xml para el documento.</div>
</div>
<div class="accordion__panel">
<h3 class="accordion__panel-title" role="tab" tabindex="3" data-qa-tag="faq-tab-4">
<div class="accordion__panel-status"></div>
¿De qué consta la estructura estándar de XHTML?
</h3>
<div class="accordion__panel-body" role="tabpanel" data-qa-tag="faq-tab-4-content">Cada documento XHTML tiene tres componentes principales: la declaración XHTML, el encabezado y el cuerpo. Los elementos de la estructura del documento son aquellos que definen cada componente.</div>
</div>
<div class="accordion__panel">
<h3 class="accordion__panel-title" role="tab" tabindex="4" data-qa-tag="faq-tab-5">
<div class="accordion__panel-status"></div>
¿Cuáles son los estándares XHTML 1.0?
</h3>
<div class="accordion__panel-body" role="tabpanel" data-qa-tag="faq-tab-5-content">El estándar XHTML 1.0 se define formalmente como tres Definiciones de Tipo de Documento (DTD) de Lenguaje de Marcado Extensible (XML): el DTD Estricto, el DTD Transicional y el DTD de Conjunto de Marcos.</div>
</div>
<div class="accordion__panel">
<h3 class="accordion__panel-title" role="tab" tabindex="5" data-qa-tag="faq-tab-6">
<div class="accordion__panel-status"></div>
¿Cuál es el anidamiento adecuado de elementos en XHTML?
</h3>
<div class="accordion__panel-body" role="tabpanel" data-qa-tag="faq-tab-6-content">Los elementos HTML pueden contener otros elementos. Esto se llama anidamiento, y para hacerlo correctamente, el elemento completo (incluido su marcado) debe estar dentro de las etiquetas de inicio y fin del elemento contenedor (el padre). El anidamiento adecuado es uno de los criterios de un documento bien formado (un requisito para XHTML).</div>
</div>
<div class="accordion__panel">
<h3 class="accordion__panel-title" role="tab" tabindex="6" data-qa-tag="faq-tab-7">
<div class="accordion__panel-status"></div>
¿Cómo agregar JavaScript en una página XHTML?
</h3>
<div class="accordion__panel-body" role="tabpanel" data-qa-tag="faq-tab-7-content">Una forma de colocar código JavaScript en su documento es a través de la etiqueta estándar HTML y XHTML. Todo lo que esté entre <script> y </script> es procesado por el navegador como declaraciones y datos ejecutables de JavaScript. No puede colocar HTML o XHTML dentro de esta etiqueta; será marcado como un error por el navegador.</div>
</div>
<div class="accordion__panel">
<h3 class="accordion__panel-title" role="tab" tabindex="7" data-qa-tag="faq-tab-8">
<div class="accordion__panel-status"></div>
¿Cuáles son los estándares XHTML?
</h3>
<div class="accordion__panel-body" role="tabpanel" data-qa-tag="faq-tab-8-content">Los documentos XHTML son conformes a XML. Como tales, se pueden ver, editar y validar fácilmente con herramientas XML estándar. Los documentos XHTML se pueden escribir para operar tan bien o mejor de lo que lo hacían antes en agentes de usuario conformes a HTML 4, así como en nuevos agentes de usuario conformes a XHTML 1.0.</div>
