cascada (del ingles <em>Cascading Stylesheets</em> <a href="/es/docs/Glossary/CSS">CSS</a>) es la siguiente tecnología que aprenderemos después de <a href="/es/docs/Glossary/HTML">HTML</a>. Mientras que HTML se utiliza para definir la estructura y la semántica del contenido, CSS se usa para darle estilo y posicionarlo visualmente. CSS se puede usar, por ejemplo, para cambiar la fuente, el color, el tamaño y el espaciado del contenido, para formar multiples columnas, añadir animaciones y otros elementos decorativos.</p></div><section aria-labelledby="itinerario_de_aprendizaje"><h2 id="itinerario_de_aprendizaje"><a href="#itinerario_de_aprendizaje">Itinerario de aprendizaje</a></h2><div class="section-content"><p>Antes de empezar con CSS deberemos conocer los fundamentos de HTML.

CSS aporta un valor añadido a HTML y no podrás aprender CSS sin controlar HTML.</p> <p>Antes de comenzar con este tema, deberemos tener conocimientos básicos sobre el uso de ordenadores y sobre el uso pasivo de la Web (navegar y consumir contenido). Es recomendable tener configurado un entorno de desarrollo como el detallado en <a href="/es/docs/Learn_web_development/Getting_started/Environment_setup/Installing_software">Instalación de software básico</a>, y saber crear y gestionar archivos como se detalla en <a href="/es/docs/Learn_web_development/Getting_started/Environment_setup/Dealing_with_files">Manejando archivos</a> — ambos forman parte del módulo <a href="/es/docs/Learn_web_development/Getting_started/Your_first_website">Primeros pasos en la Web</a> para principiantes.</p> <p>Se recomienda trabajar el módulo <a href="/es/docs/Learn_web_development/Getting_started/Your_first_website">Primeros pasos en la Web</a> antes de entrar a este tema, aunque no es completamente necesario; gran parte de lo tratado en el artículo de CSS básico también se trata en el módulo de introducción a CSS, aunque con mucho más detalle.</p></div></section><section aria-labelledby="módulos"><h2 id="módulos"><a href="#módulos">Módulos</a></h2><div class="section-content"><p>Este tema contiene los siguientes módulos en el orden recomendado de aprendizaje.

Hemos cubierto los requisitos necesarios para poder meternos de lleno en el diseño CSS, ver diferentes ajustes de visualización, metodos tradicionales de diseño con pivotes y posicionamiento, y nuevas herramientas de diseño como flexbox.</p> </dd> <dt id="diseño_adaptable_rbd_responsive_web_design"><a href="#diseño_adaptable_rbd_responsive_web_design">Diseño Adaptable (RBD Responsive Web Design)</a></dt> <dd> <p>(RWD) es una habilidad imprescindible para el diseño web.

Hojas de estilo en cascada (del ingles Cascading Stylesheets CSS) es la siguiente tecnología que aprenderemos después de HTML. Mientras que HTML se utiliza para definir la estructura y la semántica del contenido, CSS se usa para darle estilo y posicionarlo visualmente. CSS se puede usar, por ejemplo, para cambiar la fuente, el color, el tamaño y el espaciado del contenido, para formar multiples columnas, añadir animaciones y otros elementos decorativos.","title":"CSS","toc":[{"text":"Itinerario de aprendizaje","id":"itinerario_de_aprendizaje"},{"text":"Módulos","id":"módulos"},{"text":"Resolución de problemas con CSS","id":"resolución_de_problemas_con_css"},{"text":"Ver También","id":"ver_también"}],"pageType":"none"}}</script></body></html>
