За Бърза справка за HTML

Тази бърза справка за HTML поставя целия речник от тагове в една страница за търсене: скелета на документа и метаданни, текстово съдържание, семантично оформление, връзки и навигация, изображения и медия, списъци и таблици, типове входни полета на формуляри, структура и валидация на формуляри, интерактивни елементи, вградено съдържание, глобални атрибути, и обекти и специални символи.

It is as useful for the details as for the tags: which input type to use for a date or a colour, the required and pattern validation attributes, the semantic difference between article, section and aside, or the entity code for a non-breaking space and a curly quote.

Справката е безплатна и от страна на клиента: филтрирайте редовете на живо с полето за търсене, скачайте между разделите с фиксираното съдържание, копирайте всеки откъс с едно щракване и отпечатайте страницата като справочник за бюрото си.

Как да използвате Бърза справка за HTML

Прегледайте разделите, от Скелет на документа и метаданни и Семантично оформление, през Формуляри до Обекти.
Търсете таг или атрибут като picture, aria-label или required, за да филтрирате всеки ред на живо.
Отидете на Формуляри: типове входни полета, когато ви трябва правилният контрол за поле.
Щракнете върху откъс или неговата иконка за копиране, за да копирате HTML кода в клипборда си.
Отпечатайте справката за офлайн HTML справочник.

Често задавани въпроси

Дванадесет раздела: скелет на документа и метаданни, текстово съдържание, семантично оформление, връзки и навигация, изображения и медия, списъци и таблици, типове входни полета на формуляри, структура и валидация на формуляри, интерактивни елементи, вградено съдържание, глобални атрибути, и обекти и специални символи.

Да. Изградена е около съвременния HTML5: семантични елементи за разделяне, пълният набор от типове входни полета, атрибути за нативна валидация, picture и video, details и dialog.

Два раздела го правят: единият изброява всеки тип входно поле с предназначението му, другият покрива labels, fieldsets, required, pattern, min и max и останалата нативна валидация.

Да. Щракнете върху който и да е откъс или иконката за копиране при посочване и той попада в клипборда ви с кратко потвърждение.

Да, напълно безплатен: с търсене, готов за печат и визуализиран в браузъра ви без регистрация.
