I need to apply Bootstrap slide up transition effect same as to slide down. I tried many ways to do it. 

I tried to adding .fade to linear but end transition quickly gone away. Not like slide in transition. 

```
.fade-custom {
  transition: all 0.80s linear !important ;
}

```

[Jsfiddle](https://jsfiddle.net/f7zqk956/1/)

Any ways to fix this ?
