'How do I make a text fade in animation for each div on scroll down page?

The problem is the animation keeps flashing or I have to implement $(this).off('scroll'); but that can not work as there are more div's below of which need a fade in animation. What is the workaround? I need a fade in animation for the bootstrap cards and id's "ux", "da", and "hs". (option 1, option 2, option 3)


$(window).scroll(function () {
    console.log($(window).scrollTop()); // 0
    var topDivHeight = $(".image").height();
    console.log(topDivHeight); // 794
    var viewPortSize = $(window).height();
    console.log(viewPortSize); //844

    var triggerAt = 709;
    var triggerHeight = (topDivHeight - viewPortSize) + triggerAt; // 794 - 844 = -50 +709 = 659

    
    if ($(window).scrollTop() >= triggerHeight) {
        $('.noimage').css('visibility', 'visible').hide().fadeIn();
        // $(this).off('scroll');
     }  
});




$(window).scroll(function () {
    console.log($(window).scrollTop());
    var topDivHeight2 = $(".noimage").height() + $(".image").height();
    console.log(topDivHeight2);
    var viewPortSize2 = $(window).height();
    console.log(viewPortSize2);

    var triggerAt2 = 700;
    var triggerHeight2 = (topDivHeight2 - viewPortSize2) + triggerAt2;
    
    
    if ($(window).scrollTop() >= triggerHeight2) {
        $('#ux').css('visibility', 'visible').hide().fadeIn();
        // $(this).off('scroll');
     }
    
});

All you have to do is make a function in javascript for fading text

slider();
function slider(){
document.getElementById("fadingtext").style.color = "rgba(0, 0, 0,"+ document.getElementById("fader").value + ")";
document.getElementById("fadingtext").style.top =  document.getElementById("faderup").value +"px";
document.getElementById("fadingtext").style.position ="absolute";
setTimeout(slider,0);
}

#fadingtext{
 color: rgba(0, 0, 0, 0.5);
}

<div id="fadingtext">Hello World!</div><br/>
Opacity:<input id="fader" value="1" min="0.0" max="1.0" step="0.01"type="range"/>
<br/>
Move:<input id="faderup" value="0" min="0" max="100" step="1"type="range"/>

This is an example of an opacity changer that you could possibly use. probably make it go up through a variable though
