Ошибки браузеров
В настоящее время Bootstrap корректно работает с несколькими ошибками в основных браузерах и обеспечивает лучшую кросс-браузерную совменстимость. Но некоторые ошибки, перечисленные ниже, не могут быть нами решены.
Устаревший контент
Эта страница устарела и больше не применима к последним версиям Bootstrap. Сейчас он находится здесь исключительно в исторических целях и будет удален в нашем следующем крупном выпуске.
Bootstrap в настоящее время работает над несколькими выдающимися ошибками в основных браузерах, чтобы обеспечить наилучшее взаимодействие между браузерами. Некоторые ошибки, подобные перечисленным ниже, не могут быть решены нами.
Мы публично публикуем ошибки браузера, которые влияют на нашу работу, в надежде на ускорение процесса их исправления. Информацию о совместимости браузеров с Bootstrap смотрите в документации совместимости с браузером.
