bootstrap ввод, текстовая метка float-label css

0 голосов
/ 13 января 2020

Я использую Bootstrap Float-label функциональность. Ref => https://github.com/tonystar/float-label-css

Примечание. Я внес некоторые изменения в соответствии с моим требованием.

Проблемы:

1) Когда мы нажимаем на любой вход, float-label работает нормально. Но на фоне плавающей метки видна граница ввода bootstrap.

enter image description here

2) Когда происходит проверка, float-label следующего ввода разрушается, как float-label выходит над полем ввода. Я использую <span id="error_*****" class="error"></span> за пределами <span class="has-float-label">

enter image description here

3) Внешний вид в разных браузерах, как показано ниже. В IE & Edge применяется плавающая метка по умолчанию. Это нормально или какие-либо решения для IE, Edge?

Другая информация для моего случая:

Windows 10 64-бит
Firefox (версия 72.0.1)
Chrome (версия 79.0.3945.117)
Opera (версия 65.0.3467.78)
MS -Edge (версия 44.18362.449.0)
MS- IE (версия 11.535.18362.0)
Для фрагмента => Bootstrap 4.4.1 используется.

Решение 1: Установить background-color метки с плавающей запятой

Решение 2: Убрано input-group ошибки места под плавающей меткой (Полезно дать сообщение ниже поля ввода, не выше)

Решение 3: Обратите внимание, эта ссылка может быть полезной Ссылка
