Diseño responsivo con cajas flexibles CSS3
Course Overview
About This Free Course
En este curso aprenderás a desarrollar páginas responsivas por medio de la poderosa herramienta de las cajas flexibles o flex-box. Nos basaremos en la especificación más reciente de la W3C de 2014 de las "flex-box". Analizaremos desde las bases de este esquema, que nos permitirá hacer formatos o layouts, así como la forma de alinearlos vertical u horizontalmente, centrarlas, cambiar el orden de las cajas internas o ítems flexibles, así como las propiedades para "estirarlas", rotarlas y adaptarse de forma natual, las cajas internas al contenedor flexible.
Haremos ejemplos de páginas responsivas iniciando desde cero, hasta llenarlas de contenido. Realizaremos una galería responsiva con diferentes imágenes, que se adaptarán al tamaño del dispositivo, adaptándose tanto a tabletas como a teléfonos inteligentes. También haremos un ejemplo de cómo animar a las cajas flexibles por medio de las propiedades de transición de los estilos en cascada nivel tres. Por último codificaremos un menú horizontal con cajas flexibles, que cambiará su orientación a vertical cuando se visualice en pantallas pequeñas, como la de los teléfonos, donde es complicado los menús largos.
Para que puedas aprovechar este curso, es necesario que tengas conocimientos mínimos de HTML y CSS. También es deseable que conozcas HTML5 y CSS3, aunque no es indispensable.
Para tomar este curso necesitas un editor de código como SublimeText. Brackets, Aptana o Dreamweaver y un navegador moderno, así como muchas ganas de aprender.
Who Should Take This Course
"Diseño responsivo con cajas flexibles CSS3" is aimed at people who want a practical, structured introduction to development without paying full price for it. It's a solid fit if you're starting out in development and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 4.55/5 rating on Udemy. That combination — real reviews plus a working 100% OFF code — is what we look for before publishing a development course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether development is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
