How can I change the speed of the fade for alert messages in Twitter Bootstrap?

Question

I\'m using twitter bootstrap and the fade for the close on the alert box happens faster than I would like. Is there somewhere I can change the duration of the fade or perhap

Answer 1

For me on bootstrap 4, just adding these lines in my custom style.css was good enough.

.show {
    transition: opacity 100ms; // You can play with the 1
}
