/*
    Smooth transitions
    - When a new slide appears that has the class name 'carousel-item-visible' we want to trigger an animation...
    
    1) Create a new '@keyframes' at the bottom of this file called 'fadeVisibility' - kind of like a JS function! '@keyframes fadeVisibility {}'
    2) Keyframes work in steps, so 0-100 on a range. Each step you supply changes the animation sequence, e.g. 0% could be hidden and have an opacity of 0, and 100% could be showing the item by having an opacity of 1
    3) Our first keyframe step would be '0%' which sets the opacity to 0, remember that '0%' on our sequence step is not like a regular property/values, you have to use curly braces and then set your values inside there!
    4) Our second keyframe step within 'fadeVisibility' would be '100%', which sets the opacity to 1
    5) Add this keyframe animation to 'carousel-item-visible' by using the property 'animation' and pass our keyframes, those keyframes being 'fadeVisibility'
    7) Lastly after we have added our property and value to 'carousel-item-visible', we need to pass a time value (i'm going to be using seconds), so after 'animation: fadeVisibility' pass a time value. I'm going to use 0.5s - which should look like this: 'animation: fadeVisibility 0.5s'
    
    Info: So from 0% - 100% in our keyframes we wait 0.5 seconds and go from an opacity of 0, to an opacity of 1!
