-WebSockets
-
-_Web Sockets_ هي تقنية تسمح لك بإنشاء اتصال تفاعلي بين العميل والخادم لتبادل البيانات في الوقت الحقيقي. WebSockets تسمح لك بالعمل في اثنين من دفق ، والذي يميز هذه التكنولوجيا من HTTP.
-
-## كيف يعمل WebSockets؟
-
-لا يحتاج WebSockets إلى مكالمات متكررة للرد. يكفي تقديم طلب واحد وانتظر الرد. يمكنك الاستماع إلى الخادم ، والذي سوف يرسل الإجابة على الاستعداد.
-
-## متى يمكنني استخدام WebSockets؟
-
-* تطبيقات في الوقت الحقيقي
-* تطبيق الدردشة
-* تطبيقات إنترنت الأشياء
-* ألعاب متعددة اللاعبين
-
-## متى لا تستخدم WebSockets؟
-
-يتم دعم WebSockets بالفعل في 95٪ من المتصفحات ، ولكن في بعض الأحيان لا تكون هذه التقنية مطلوبة. على سبيل المثال ، إذا كنت تقوم بإنشاء CMS بسيط حيث لا تكون وظيفة الوقت الحقيقي مطلوبة.

-## 引导
-
-迄今为止最着名的CSS框架之一。包括用于绘制按钮，侧边栏，导航栏，表单和其他网站元素的模板。包括自己的JavaScript扩展。
-
-Bootstrap与所有主流现代浏览器兼容，但旧版浏览器可能存在问题。支持适应性。使用Less和Sass语言。
-
-## 骨架
-
-它基于JavaScript和CSS，用于快速准确地创建在大型监视器和小型小工具屏幕上正确显示的响应式网站。一个大加骷髅 - 它可以适应任何设计。标记网格包含12列，基本宽度为960像素。兼容所有主流浏览器。
-
-## KUBE
-
-开发人员完全自由而不强加风格。提供最大的设计灵活性它有几个网格选项，由创建者定位为专业CSS开发人员的框架。使用Less，支持响应式设计。
-
-## 基础
-
-常见的CSS框架。与其他主要元素一起包括几个HTML模板，页面上具有不同的块排列。它在JavaScript中有很多组件。该框架的能力和构成非常严肃。使用Sass。与所有主流浏览器兼容的代码。
-
-## 语义UI
-
-支持Firefox，Chrome，Safari，Internet Explorer，Android 4，Blackberry10。包含大量组件：图标，图像，标签，菜单和其他标准组件。它支持最新版本的HTML和CSS，并且有很多脚本模块和API可供选择。使用更少。适用性与bootstrap竞争。

-Estrutura CSS comum. Juntamente com outros elementos principais inclui vários modelos HTML com diferentes arranjos de blocos na página. Tem um grande conjunto de componentes em JavaScript. A estrutura é muito séria em suas capacidades e composição. Usa Sass. Código compatível com todos os principais navegadores.
-
-## IU semântica
-
-Suporte para Firefox, Chrome, Safari, Internet Explorer, Android 4, Blackberry10. Contém um grande número de componentes: ícones, imagens, etiquetas, menus e outros componentes padrão. Ele suporta as versões mais recentes de HTML e CSS e possui uma boa seleção de módulos de script e APIs. Usa menos. Na aplicabilidade compete com o bootstrap.

-WebSockets
-
-_Web Sockets_ é uma tecnologia que permite criar uma conexão interativa entre um cliente e um servidor para a troca de dados em tempo real. Os WebSockets permitem trabalhar em dois fluxos, o que distingue esta tecnologia do HTTP.
-
-## Como funcionam os WebSockets?
-
-Os WebSockets não precisam de chamadas repetidas para responder. É o suficiente para fazer um pedido e esperar por uma resposta. Você pode ouvir o servidor, que enviará a resposta em prontidão.
-
-## Quando posso usar WebSockets?
-
-* Aplicativos em Tempo Real
-* Aplicação de chat
-* Aplicativos IoT
-* Jogos multiplayer
-
-## Quando não usar WebSockets?
-
-WebSockets já são suportados em 95% dos navegadores, mas às vezes essa tecnologia não é necessária. Por exemplo, se você estiver criando um CMS simples em que a funcionalidade em tempo real não seja necessária.

-WebSockets
-
-_Web Sockets_ - это технология, позволяющая создавать интерактивное соединение между клиентом и сервером для обмена данными в режиме реального времени. WebSockets позволяет работать в двух потоках, что отличает эту технологию от HTTP.
-
-## Как работают WebSockets?
-
-WebSockets не требует повторных вызовов для ответа. Достаточно сделать один запрос и ждать ответа. Вы можете прослушивать сервер, который отправит ответ на готовность.
-
-## Когда я могу использовать WebSockets?
-
-* Приложения реального времени
-* Приложение чата
-* Приложения IoT
-* Мультиплеерные игры
-
-## Когда не использовать WebSockets?
-
-WebSockets уже поддерживаются в 95% браузеров, но иногда эта технология не требуется. Например, если вы создаете простую CMS, где функциональность в реальном времени не требуется.

- * Code uniformity
- * Increase development speed

-
-Uno de los frameworks CSS más famosos hasta la fecha. Incluye plantillas para botones de dibujo, barras laterales, barras de navegación, formularios y otros elementos del sitio. Incluye en sí las extensiones de javascript.
-
-Bootstrap es compatible con todos los principales navegadores modernos, pero puede haber problemas en versiones anteriores de los navegadores. Soporta adaptabilidad. Utiliza los lenguajes Less y Sass.

-## Esqueleto
-
-Basado en JavaScript y CSS, se utiliza para crear de forma rápida y precisa sitios web receptivos que se muestran correctamente tanto en monitores grandes como en pantallas de dispositivos pequeños. Un gran esqueleto más: se puede adaptar a cualquier diseño. La cuadrícula de marcado contiene 12 columnas y tiene un ancho base de 960 píxeles. Compatible con todos los principales navegadores.
-
-## Kube
-
-Completa libertad para el desarrollador sin imponer estilos. Proporciona la máxima flexibilidad de diseño. Tiene varias opciones de cuadrícula y los creadores lo posicionan como un marco para desarrolladores de CSS profesionales. Utiliza menos, soporta diseño responsivo.
-
-## Fundación
-
-Marco CSS común. Junto con otros elementos principales, incluye varias plantillas HTML con diferente disposición de bloques en la página. Tiene un gran conjunto de componentes en JavaScript. El marco es muy serio en sus capacidades y composición. Utiliza Sass. Código compatible con todos los principales navegadores.
-
-## IU semántica
-
-Soporte para Firefox, Chrome, Safari, Internet Explorer, Android 4, Blackberry10. Contiene una gran cantidad de componentes: iconos, imágenes, etiquetas, menús y otros componentes estándar. Es compatible con las últimas versiones de HTML y CSS y tiene una buena selección de módulos de script y API. Utiliza menos. En aplicabilidad compite con bootstrap.
-
-Cada tarea tiene su propia herramienta. Un buen paso sería probar el marco y entenderlo "tuyo" o no. Puede usar los esqueletos del código presentado en los marcos como una hoja de trucos y simplemente tomar soluciones y código desde allí.

-_Web Sockets_ es una tecnología que le permite crear una conexión interactiva entre un cliente y un servidor para intercambiar datos en tiempo real. WebSockets le permite trabajar en dos flujos, lo que distingue esta tecnología de HTTP.
-
-## ¿Cómo funcionan los websockets?
-
-WebSockets no necesita llamadas repetidas para responder. Basta con hacer una solicitud y esperar una respuesta. Puede escuchar el servidor, que enviará la respuesta a la preparación.
-
-## ¿Cuándo puedo usar WebSockets?
-
-* Aplicaciones en tiempo real
-* Aplicación de chat
-* Aplicaciones de IoT
-* Juegos multijugador
-
-## ¿Cuándo no usar WebSockets?
-
-Los WebSockets ya son compatibles con el 95% de los navegadores, pero a veces esta tecnología no es necesaria. Por ejemplo, si está creando un CMS simple donde no se requiere la funcionalidad en tiempo real.
