Custom Transitions

1. Set transition to "None"

Title Text

Subtitle

2. Define transitions using the CSS editor

// Select all slides and backgrounds that do not have a
// per-slide transition set via `data-transition`
.slides > section:not([data-transition]),
.backgrounds > .slide-background:not([data-transition]){
    transition: all 1s ease !important;
    
    &.past {
        transform: rotate(45deg) translateX(-100%);
        opacity: 0;
    }
    
    &.future {
        transform: rotate(-45deg) translateX(100%);
        opacity: 0;
    }   
}

3. Slide-specific transitions

Press "Shift + Option + A" to open Advanced Slide Options and give your slide a class name. Now you can target the slide like so:

.slides > section:not([data-transition]),
.backgrounds > .slide-background:not([data-transition]){
    transition: all 0.8s ease !important;
    
    &.my-custom-class.past {
        transform: scale(0.2);
        opacity: 0;
    }
    
    &.my-custom-class.future {
        transform: scale(0.2);
        opacity: 0;
    }
}
