Making animations in react without using Jquery

I am trying to create a on scroll fade animation in my website i am using reactjs for this although i didnt knew how to bring this effect so i found this jquery code to achive this effect but i want to bring this effect without jquery using plane react is it possible? here is the jquery code:
var html = $('html');
// Detections
if (!("ontouchstart" in window)) {
html.addClass("noTouch");
}
if ("ontouchstart" in window) {
html.addClass("isTouch");
}
if ("ontouchstart" in window) {
html.addClass("isTouch");
}
if (document.documentMode || /Edge/.test(navigator.userAgent)) {
if (navigator.appVersion.indexOf("Trident") === -1) {
html.addClass("isEDGE");
} else {
html.addClass("isIE isIE11");
}
}
if (navigator.appVersion.indexOf("MSIE") !== -1) {
html.addClass("isIE");
}
if (
navigator.userAgent.indexOf("Safari") != -1 &&
navigator.userAgent.indexOf("Chrome") == -1
) {
html.addClass("isSafari");
}
// On Screen
$.fn.isOnScreen = function() {
var elementTop = $(this).offset().top,
elementBottom = elementTop + $(this).outerHeight(),
viewportTop = $(window).scrollTop(),
viewportBottom = viewportTop + $(window).height();
return elementBottom > viewportTop && elementTop < viewportBottom;
};
function detection() {
for (var i = 0; i < items.length; i++) {
var el = $(items[i]);
if (el.isOnScreen()) {
el.addClass("in-view");
} else {
el.removeClass("in-view");
}
}
}
var items = document.querySelectorAll(
"*[data-animate-in], *[data-detect-viewport]"
),
waiting = false,
w = $(window);
w.on("resize scroll", function() {
if (waiting) {
return;
}
waiting = true;
detection();
setTimeout(function() {
waiting = false;
}, 100);
});
$(document).ready(function() {
setTimeout(function() {
detection();
}, 500);
for (var i = 0; i < items.length; i++) {
var d = 0,
el = $(items[i]);
if (items[i].getAttribute("data-animate-in-delay")) {
d = items[i].getAttribute("data-animate-in-delay") / 1000 + "s";
} else {
d = 0;
}
el.css("transition-delay", d);
}
});
});
is there any way that i can bring this effect from react only or do i have to use :
import $ from jquery
thanks in advance

This is the script, located at http://churchofcwa.wikia.com/wiki/MediaWiki:Common.js/bglinks.js, that I am encountering an error with css, this script was copied from https://www.biblegateway.com/public/link-to-us/tooltips/bglinks.js and is not made by me. The issue I am encountering is via the css page (MediaWiki:Common.css) when changing the color of the script by
.bg_popup-content-bible {color:#000000}
The font color of the p tag within that div does not change. Originally I had it set to the p tag specifically of that div, but a css checker said that styling would be overqualified, and it was not functional nevertheless. What the script does is take all Bible verses listed on a page, and automatically links them to Biblegateway and creates a preview popup when hovering. However, the font is very unreadable and so I have tried to change it to black.
The popup currently has a near-white font (that blends with the popup)
and needs to have a black font, with the rest of the page content needs the near white font. When the script runs through it generates a div surrounding each bible verse, and the js applies to it (the div in which the Bible verse text appears is in the bg_popup-content-bible with a <p> tag), making it popup like so.
I have noted that in the script there is a section that calls for a "addedCSS"
var addCSS = function() {
if (!addedCSS) {
var css = document.createElement('link');
css.type = "text/css";
css.rel = "stylesheet";
if (browser.search('MSIE 6.0') != -1) {
browser = 'ie6';
css.href = cdHost + '/theme/bglinks-ie.css';
} else {
css.href = cdHost + '/theme/popover.css';
}
css.media = "screen";
var n1 = document.getElementsByTagName("head")[0].childNodes[0]
n1.parentNode.insertBefore(css, n1);
addedCSS = true;
}
}
I do not believe it is possible to change the url that the addedCss pull from, from the MediaWiki:Common.css, as this script was not made for the specific system being used (when removing or altering the variable the script does not work). I don't know if this is not happening because of a javascript issue (which is beyond me, and it's difficult to alter the script without breaking it) or if it's just a matter of incorrect css, but I have been working on this for several months here and there, and would like to get this final detail to work.

Try changing it to
.bg_popup-content-bible {color:#000000 !important;}

Ignore the CSS specificity checker. I have tested the below css on your site and it works. Make sure to put it in your site.css.
.bg_popup-content-bible p {
color: #000000;
}
It needs to be written as above because it has to override the <p> styling you've already set earlier in site.css:
p {
color: #f5f5f5
}
EDIT
It is not a problem with the script. Based on what you have said in the comments it seems like you are unable to actually edit / output css. So the other option is just to modify the script you've posted above:
Change this:
tooltip.innerHTML = '<div class="bg_popup-header"><div class="bg_popup-header_title"><strong>'+reference_display+' '+tooltip_content.version+'</strong></div></div><div class="bg_popup-content"><div class="bg_popup-content-bible"><p>'+tooltip_content.text+' <a class="bg_popup-copyright" href="'+bgHost+tooltip_content.version_url+'" target="_blank">('+tooltip_content.version+')</a> <a class="bg_popup-more" href="'+bgHost+'/passage/?search='+tooltip_content.reference+'&version='+tooltip_content.version+'&src=tools" target="_blank">More</a></p></div></div><div class="bg_popup-footer"><a class="bg_popup-bglogo" href="'+bgHost+'/" target="_blank"></a></div>';
to this:
tooltip.innerHTML = '<div class="bg_popup-header"><div class="bg_popup-header_title"><strong>'+reference_display+' '+tooltip_content.version+'</strong></div></div><div class="bg_popup-content"><div class="bg_popup-content-bible"><p style="color:#000000">'+tooltip_content.text+' <a class="bg_popup-copyright" href="'+bgHost+tooltip_content.version_url+'" target="_blank">('+tooltip_content.version+')</a> <a class="bg_popup-more" href="'+bgHost+'/passage/?search='+tooltip_content.reference+'&version='+tooltip_content.version+'&src=tools" target="_blank">More</a></p></div></div><div class="bg_popup-footer"><a class="bg_popup-bglogo" href="'+bgHost+'/" target="_blank"></a></div>';
Given the way Stack formats the code above, to make it very clear you are editing the part of the line above that says:
<p>'+tooltip_content.text+'
and making it:
<p style="color:#000000">'+tooltip_content.text+'

How to add a padding top to smooth scroll

I have implemented a javascript smooth scroll in a one page site and works perfectly. However, because I have a fixed nav at the top of the page, when the page scrolls to the anchor, the top of the page disappears behind the nav. How can I offset the scroll of 90px?
Here is the code:
var ss = {
fixAllLinks: function() {
// Get a list of all links in the page
var allLinks = document.getElementsByTagName('a');
// Walk through the list
for (var i=0;i<allLinks.length;i++) {
var lnk = allLinks[i];
if ((lnk.href && lnk.href.indexOf('#') != -1) &&
( (lnk.pathname == location.pathname) ||
('/'+lnk.pathname == location.pathname) ) &&
(lnk.search == location.search)) {
// If the link is internal to the page (begins in #)
// then attach the smoothScroll function as an onclick
// event handler
ss.addEvent(lnk,'click',ss.smoothScroll);
}
}
},
smoothScroll: function(e) {
// This is an event handler; get the clicked on element,
// in a cross-browser fashion
if (window.event) {
target = window.event.srcElement;
} else if (e) {
target = e.target;
} else return;
// Make sure that the target is an element, not a text node
// within an element
if (target.nodeName.toLowerCase() != 'a') {
target = target.parentNode;
}
// Paranoia; check this is an A tag

Thanks in advance for your help!

You can do a calculation when setting the destination coordinates:
// Find the destination's position
var destx = destinationLink.offsetLeft;
var desty = destinationLink.offsetTop;
var thisNode = destinationLink;
while (thisNode.offsetParent &&
(thisNode.offsetParent != document.body)) {
thisNode = thisNode.offsetParent;
destx += thisNode.offsetLeft;
desty += thisNode.offsetTop;
}
//subtract nav from offset position
desty = desty - 90;
if(desty < 0){ desty = 0; }
That being said, using a static number is dangerous business. Might make more sense to calculate minus the header's actual height instead.

Simply make changes in the CSS:
html{
scroll-behavior: smooth;
scroll-padding-top: 50px;
}
This will handle your fixed header issue.

How to make this floating menu work only when specific #divs become visible?

The script requires the menu to have #floatdiv id. I made my div, #floatdiv, and added the following line of javascript to the head to make the action start working:
<script type="text/javascript">
floatingMenu.add('floatdiv',
{
targetLeft: 250,
targetTop: 290,
snap: true
});
</script>
the #floatdiv css is here,
#floatdiv{
height:45px;
width:830px;
z-index:2;
}
The script is working fine. When I scroll down, the menu float as specified. But I dun wanna the menu to float all the way with scrolling. I need the float of the menu to fire only when I enter specific divs not all the way with scrolling.. Any clues?

is this what look like?
html
<div id="header">HEADER</div>
<div id="content">
<div id="left">LEFT</div>
<div id="right">RIGHT</div>
</div>
<div id="footer">FOOTER</div>
js
$(function() {
var $sidebar = $("#right"),
$window = $(window),
rightOffset = $sidebar.offset(),
rightDelta = $("#footer").offset().top - $("#header").offset().top - $("#header").outerHeight() - $("#right").outerHeight(),
topPadding = 15;
$window.scroll(function() {
$sidebar.stop().animate({
marginTop: Math.max(Math.min($window.scrollTop() - rightOffset.top + topPadding, rightDelta), 0)
});
});
});
working demo
hope this help you

I wrote the script listed in the question.
The script is very versatile and can make div float within a specific area (e.g. another container div). Here are the instructions:

Trying to find javascript element's position on screen....Not working properly on webkit browsers

This is the code i'm using right now. On webkit browsers (Chrome and Safari Specifically) if the page is scrolled, it doesn't take into account the amount that page has been scrolled. I need help redesigning the function to work for Webkit browsers. And I don't want to be loading up jQuery as this will be used on a web widget and I need to keep the file size down. Thanks guys!
