UPDATE2
scratch the previous update
Although I got it to work to a fashion, it is so much work & fraught with possible errors and a significant loss of loading speed I don't think it's worth doing.

The problem with using the class "outofview" and trying to add the 'animation-iteration-count" thingy
is that the actual "outofview" is controlled by some JS which is built within Site Designer foundation framework, what that does put simply is it looks at any element with the class "outofview" calculates it's position if its out of view, it adds the class "out of view" if it comes into view, it removes the class "out of view"
So the "animation-iteration-count" thingy fires off no problem for the first time, but because the class name gets added if the user scrolls again up or down, then the class name gets removed and added again, resulting in the animation-iteration-count thingy, actually losing count and thinks it's got to start again.

I have been fiddling with this since very early this morning, and have just come up against brick walls.

If someone out there is a guru with JS, then it might be possible to make the adding/removal of a class name (with the same actions as the JS for "outofview" but make it so it only happens once, that way it may be possible to do what Ed wishes to do, (and me for that matter)
until then
ED I'm sorry I cant come up with anything workable from within Site Designer unless it's using custom CSS and custom JS I await with eager anticipation in-case someone comes up with something less intensive

You could use a simple plugin called Scrolla if you want to use animate.css (I would use version 3 which is a option in the settings when initializing the plugin)

I did a small modification to only have the animations happen when scrolling down....not back up.

I added in the option of using the data-once="true" if you prefer the animation to only happen once and not repeat.

I removed the offset setting also.

Thats great Twinstrean except Ed is using "outofview" from site designer itself,,
but what you have is really cool too

Need to refresh been a long time, link removed

As per my opinion, you typically can't create complex animations like those you're describing purely within a responsive design tool like RSD (Responsive Site Designer) without adding custom code.

RSD and similar tools are often designed to simplify the design process and handle the basics, but more advanced features like scroll-triggered transitions might require custom coding, typically with JavaScript and CSS. Libraries such as ScrollMagic or AOS (Animate On Scroll) can be useful in creating these effects.

I hope this will help you.

To create active transitions to elements on a website, you can use CSS (Cascading Style Sheets) animations and transitions. These techniques allow you to add smooth and engaging effects when elements change states or properties. Here are some examples of how to create active transitions using CSS:

Fade-in and Fade-out:
css
Copy code
/* HTML */
<div class="element"></div>

/* CSS */
.element {
opacity: 0; /* Initially hidden */
transition: opacity 0.3s ease;
}

.element.active {
opacity: 1; /* Fades in when 'active' class is added */
}
Slide-in from Left:
css
Copy code
/* HTML */
<div class="element"></div>

/* CSS */
.element {
transform: translateX(-100%); /* Initially off-screen to the left */
transition: transform 0.5s ease;
}

.element.active {
transform: translateX(0); /* Slides in from the left when 'active' class is added */
}
Scale on Hover:
css
Copy code
/* HTML */
<div class="element"></div>

/* CSS */
.element {
transform: scale(1); /* Normal size */
transition: transform 0.3s ease;
}

.element:hover {
transform: scale(1.2); /* Scales up on hover */
}
Color Change on Click:
css
Copy code
/* HTML */
<div class="element"></div>

/* CSS */
.element {
background-color: blue; /* Initial color */
transition: background-color 0.3s ease;
}

.element.active {
background-color: red; /* Changes color to red when 'active' class is added */
}
Rotate on Button Click:
css
Copy code
/* HTML */
<div class="element"></div>
<button onclick="toggleRotation()">Rotate</button>

/* CSS */
.element {
transform: rotate(0deg); /* Initially no rotation */
transition: transform 0.5s ease;
}

.rotate-active {
transform: rotate(45deg); /* Rotates 45 degrees when 'rotate-active' class is added */
}
In the above examples, the 'active' class is added or removed from the HTML element through JavaScript or user interactions. The CSS transitions smoothly animate the change of properties when the 'active' class is toggled. You can customize the transition duration, timing function (ease, linear, ease-in, ease-out, etc.), and other properties to achieve the desired effect.

Remember to add vendor prefixes (-webkit-, -moz-, -ms-, -o-) for cross-browser compatibility when using some CSS properties. Also, JavaScript can be used to toggle the 'active' class on elements in response to user actions like clicks, hovers, or other events.

There's no examples anywhere I can find. Surprising that it is not included since it seems to be standard with other folks.

Perhaps the difficulty for a one-time occurrence on scrolling into view is the attempt to use the 'Out of View' state. The source code produced by SD pages suggests that this is achieved by the file outofview.js with which we probably cannot (or should not) meddle.

If one uses instead IntersectionObserver in JavaScript, one can simply turn it off once it has fired (as shown at line 10 of the script in the attached file).
