- Посібники для розробників
Відкритий веб надає дивовижні можливості для розробників. Щоб скористатися усіма перевагами цих технологій, потрібно розуміти, як їх застосовувати. Нижче наведено посилання на документацію про різні вебтехнології.
Документація для веброзробників
- Посібник веброзробника
Посібник веброзробника пропонує корисні матеріали, які допоможуть вам використовувати вебтехнології для виконання того, що ви хочете або повинні зробити.
- Підручники для веброзробників
Набір підручників, які крок за кроком проведуть вас через вивчення HTML, CSS, JavaScript й API Вебу.
- Доступність
Про те, як зробити використання вебсайтів можливим для якомога більшої кількості людей, навіть якщо можливості цих людей певним чином обмежено.
- Ефективність
Про те, як зробити вміст якомога доступнішим та інтерактивнішим, якомога швидше.
- Безпека
Захист користувачів від витоку даних та крадіжки даних, атак сторонніми каналами, а також міжсайтового програмування, ін'єкцій вмісту та перехоплення клацань.
Довідник з вебтехнологій
- API Вебу
API програмування на JavaScript, які можна використовувати для створення застосунків у Вебі.
- HTML
HTML надає основні (базові) цеглини для структурування вебдокументів та вебзастосунків.
- CSS
Каскадні списки стилів використовуються для опису зовнішнього вигляду вебдокументів та вебзастосунків.
- JavaScript
JavaScript – це рідна мова програмування Вебу.
- WebAssembly
WebAssembly дає змогу програмам, написаним на C, C++, Rust, Swift, C#, Go та інших мовах, працювати у Вебі.
- Події
Події – це те, для реагування на що створюються вебзастосунки; наприклад, коли вебсторінка завершує своє завантаження, або коли користувач щось обирає, натискає клавішу, змінює розмір вікна, подає форму чи призупиняє відео.
- HTTP
HTTP – це фундаментальний протокол Інтернету для отримання документів, списків стилів, сценаріїв, зображень, відео, шрифтів та інших ресурсів крізь Веб – а також для надсилання даних назад на вебсервери.
- Медіа
Формати, кодеки, протоколи, API та техніки для вбудування та потокового відтворення відео, аудіо та зображень у вебдокументах і вебзастосунках.
- SVG
Масштабовна векторна графіка дає змогу описувати зображення, що плавно масштабуються до будь-якого розміру.
- MathML
MathML дає змогу показувати складні математичні формули у Вебі.
- Вебкомпоненти
Вебкомпоненти – це елементи, які можна самотужки визначити та багаторазово використовувати у вебзастосунках.
- WebDriver
WebDriver – це механізм автоматизації браузерів для віддаленого керування браузером шляхом імітування дій справжньої людини, що ним користується. Широко використовується для тестування вебзастосунків у різних браузерах.
- Веброзширення
Веброзширення – спосіб надати користувачам у їхніх браузерах розширені можливості, наприклад, блокування реклами та іншого вмісту, налаштування вигляду сторінок та інше.
- Декларації вебзастосунків
Декларації вебзастосунків дають користувачам змогу встановлювати вебзастосунки на домашні екрани своїх пристроїв, з наперед визначеними аспектами штибу вертикального чи горизонтального орієнтування екрана, режиму відображення (наприклад, повноекранного) тощо.
- Поступові вебзастосунки (PWA)
Поступові вебзастосунки пропонують користувацький досвід, подібний до нативних мобільних застосунків.
