I have a page with up and down arrows that are links that float on the left. I want them to navigate between div's on the page as a scrolling anchor links. Here is what I have so far.....I know the jquery is far from complete but I think im going in the right direction. Any help would be great.

JQUERY:
jQuery(document).ready(function(){
var jumptosectionTopPosition = jQuery('.jumptosection').offset().top;
jQuery('#scroll').click(function(){
jQuery('html, body').animate({scrollTop:jumptosectionTopPosition}, 'slow');
return false;
});
});
Change hrefs of your <a> to scrollUp and scrollDown correspondingly.
Stick to some .selected class, which will be used for identifying current selected section.
Add this class to the first section in html.
Add a function that will perform selection: by adding .selected class and scrolling to newly selected div.
function changeSelection(sectionFrom, sectionTo) {
if(sectionTo.length > 0) {
sectionFrom.removeClass("selected");
sectionTo.addClass("selected");
$("body").animate({scrollTop: sectionTo.offset().top});
}
}
Attach click listeners to your anchors. Inside each of them find current selected div and div you want to be selected and call changeSelection() using these divs.
For scrollDown we want to select the next div:
$(document).on("click", "[href='#scrollDown']", function(){
var currentSection = $(".selected");
var nextSection = currentSection.next(".jumptosection");
changeSelection(currentSection, nextSection);
return false;
});
For scrollUp we want to select the previous div:
$(document).on("click", "[href='#scrollUp']", function(){
var currentSection = $(".selected");
var prevSection = currentSection.prev(".jumptosection");
changeSelection(currentSection, prevSection);
return false;
});
In case you reach the end (the first or the last .jumptosection div), nothing will be changed (it is controlled by the changeSelection function - it checks do we have sectionWeWantScrollTo)
Here is the Demo
Edited (for http://94co.com/client3/about/)
See this answer about WordPress and jQuery. Use jQuery instead of
$ in your script
It is better to use id instead of href on anchor
Make sure you wrap JavaScript of click listeners in
jQuery(document).ready(function(){
/*scrollUp and scrollDown click listeners should be here*/
});
(JSFiddle makes this wrap automatically). changeSelection function doesn't need to be wrapped
Here is the updated Demo
You can set some initial var that let you know the start point like this:
var pre = $('.et-float-menu-item1'),
nex = $('.et-float-menu-item2'),
act = $('#section1');
Where act is the start
And then evaluate prev and next elements:
nex.click(function(){
pre.slideDown();
var gt = act.next('div').offset().top;
$('body').animate({scrollTop : gt},'slow');
act = act.next('div');
})
pre.click(function(){
var gt = act.prev('div').offset().top;
$('body').animate({scrollTop : gt},'slow');
act = act.prev('div');
})
This code can be improved but is the first aproach I can give.

So I have this great little nugget of code that I am trying to rewrite into plain JavaScript and CSS without jQuery.
jQuery.extend(jQuery.easing,{
easeInExpo: function (x, t, b, c, d) {
return (t==0) ? b : c * Math.pow(2, 10 * (t/d - 1)) + b;
}
});
var nset = false;
$('button#hmenu').click(function(){
if(!nset){
$('ul#nav').delay(35).slideDown(300,'easeInExpo');
$('button#hmenu').addClass('active');
nset = true;
} else {
$('ul#nav').slideUp(550);
nset = false;
$('button#hmenu').removeClass('active');
}
})
I'm looking at some CSS transitions that use easing but just wondering what the options are? In my code I have a slideDown and up easing functions. This is used in production for a mobile menu nav.
Update:
This github repo (You don't need jQuery) has a really comprehensive list of common jQuery functions, all rewritten in vanilla Javascript.
It includes animations, query selectors, ajax, events and other advanced jQuery features.
The slightly older youmightnotneedjquery.com is also very good, particularly if you need to support older IE versions.
You can achieve an easeInExpo style animation by using the following CSS, as provided by this website:
transition: all 500ms cubic-bezier(0.950, 0.050, 0.795, 0.035);
The below example illustrates this easing property on the height of a div. I've updated it to match the delay you've added in jQuery when clicked (35ms), the timings (300ms and 550ms respectively), and jQuery's default easing ('swing') – as provided by this answer – when it's closed:
let expandable = document.getElementById('expandable');
let expandButton = document.getElementById('expand-button');
expandButton.addEventListener('click', () => {
expandable.classList.toggle('expanded');
});
#expandable {
background: red;
transition: all 550ms cubic-bezier(.02, .01, .47, 1);
height: 0px;
width: 100px;
transition-delay: 0ms;
}
#expandable.expanded {
height: 100px;
transition-delay: 35ms;
transition: all 300ms cubic-bezier(0.950, 0.050, 0.795, 0.035);
}
<div id="expandable"></div>
<br />
<button id="expand-button">Toggle expand</button>
There's a little bit of magic needed here in order to get your collapsible component to expand to a variable height. If you are just expanding to the same height each time, say 100px, that's a simple as creating a single class such as "expanded" and then adding and removing that class as a boolean switch.
We'll still be using a boolean switch for variable heights, but we'll also need to get the heights of each expandable element using JavaScript, and then refresh those height values if the size of the user's window changes to account for text-wrapping, image resizing, etc.
We can achieve rather simply using custom CSS properties (variables), with a fallback value to unset, meaning that when to variable height is present, the box will expand to show all contents without an animation as a last resort, but in most if not all cases (and for all modern browsers) the custom CSS variable should be the ideal solution for unique values per section.
Here it is in action (below), with both a toggle and accordion example, with a cubic bezier easing function used to closely match the easeInExpo function you supplied in your original question. I pulled this easing function cubic-bezier(0.95, 0.05, 0.795, 0.035) from easings.net/en#easeInExpo where they have a pure CSS easing for easeInExpo and many others.

if (e.target?.matches('.expand-trigger')) {
const expandable = e.target.nextElementSibling;

Other CSS easing functions are available at easings.net.
You can also customize your easing function visually using Chrome's DevTools by adding either the transition or transition-timing-function properties to any element with the value of ease, then clicking the square curve icon next to the word ease and dragging either of the circular handles.
I'm trying to design a small menu and I really like this code. As you normally know, menus are closed when the page is first loaded. How can I make this animation closed when the page is first loaded? How can I start this animation in reverse?
$(document).ready(function(){

});
.box{

}
/* Add padding and border to inner content
for better animation effect */
.box-inner{

When the menu is closed, it adds display: none property to the .box element. You have to add this style property to the .box element in HTML to make it look trapped on boot.
I've tried a few suggestions like removing overflow from the body, adding a z-index to header and padding-top but nothing seems to work.
It worked fine at first but then I implemented a lot of Lorem Ipsum text. All the content just slides up and below the navbar. I've attached a JS fiddle to explain.
I tried the whole body overflow and tried the fixed/relative header positions. Nothing works.
Any input would seriously be appreciated A LOT.
I would love some help in how can I make the nav stick but not really stay fixed when I scroll down.
And of course, how to make the contents not overflow horizontally.
Please help!

Thank you so much.
You want for header to always stay on top, but to not cover your content, correct?
If i got you right then what you need to do is to to change your main content wrapper which is #about element, you need to have only this element scrollable, not whole page.
For this i propose this css:
#about {
max-width: 100%;
position:relative;
top:100px;
border: 5px solid purple;
padding: 20px;
text-align: center;
justify-content: center;
height:100px;
overflow:scroll;
}
So here we are chaging the position to be relative, so we can move the content down by the height of navigation (top:100px)
Then we limit the height of this component (height:100px) and making it scrollable (overflow:scrool) - so that you can scroll, and when you do - you scrolling on the content, not the whole page, so navbar with fixed position is staying on top
Here is the fiddle - https://jsfiddle.net/t2a4938f/12/
I've set approximate values, you can play around for better view
UPDATE
And if you want for the content to take full height of the screen (not limiting to some strict height like above - 100px), you could use height:100vh
Because you are using bootstrap, I link you my jsfiddle that should work for you.
No css or js needed, bootstrap will do the work for you
JSFIDDLE: https://jsfiddle.net/9yeb023u/1/
I created a basic navbar but you can customize it, if you have any problem go to the documentations of bootstrap at this link:
https://getbootstrap.com/docs/4.5/getting-started/introduction/
The header is sticky and the body content would always below the header.
h.header {
width: 100%;
top: 0;
position: sticky;
background-color: black;
}
#about {
max-width: 100%;
border: 5px solid purple;
padding: 20px;
text-align: center;
justify-content: center;
}
I currently have a paragraph tag in html that has long text inside of it. I also have a button that when clicked should expand and retract the section of text. This is used because the text is too long so I am adding a "Read More" button to expand and show the full text. Right now I am unable to get the paragraph to expand. Instead when the button is clicked it fades into the background and never show.

You can use .animate() to animate changes with CSS. For this script, it would be best then set the height to meet that of the entire text. The scrollHeight property of the element gives us this the number of pixels that is equal to the full height of the box even though we have no overflow and the height is already set.
I use the callback option in .fadeOut() to ensure that the fade animation completes before we start a new animation to reveal the text.
I also found this article if you want to fiddle with ellipse like styling: http://hackingui.com/front-end/a-pure-css-solution-for-multiline-text-truncation/

My goal is given 2 divs, one with tagged content, generate new content in the other div that is vertically aligned with the first. A minimal example of what I've got so far is below in the snippet.
I've tried doing adjustments like subtracting $('sidebar').offset().top and/or the height of the header from the new element's top-side offset (thinking that maybe the new element was offsetting from the top of the sidebar instead of the document for some reason), but that still doesn't put it in the right place.
I think the hurdle here is figuring out why tag_offset.top and test_tip.offset().top aren't equal at the end, even though that's explicitly being assigned when test_tip is instantiated.
var tag_offset = $('.jt-tooltip-tag').offset();
tag_offset['left'] = 0;
var tag_text = $('.jt-tooltip-text').text();
var test_tip = $('<div class="jt-sidebar-tip">').text(tag_text).offset(tag_offset).appendTo('#jt-tooltip-sidebar');
.middlebar {
width: 49%;
float: left;
}
.sidebar {
height: 500px;
width: 49%;
float: right;
border: 1px solid purple;
}
.jt-tooltip-tag {
font-weight: bold;
background-color: #14c9c9;
}
.jt-tooltip-text {
display: none;
}
.jt-sidebar-tip {
position: relative;
}

In order to position an element relative to the document, you need to set its CSS to position: absolute;. But then you also need to set its left offset to a position that puts it into its container. I've done this by copying $("#jt-tooltip-sidebar").offset().left.
var tag_offset = $('.jt-tooltip-tag').offset();
tag_offset.left = $("#jt-tooltip-sidebar").offset().left;
var tag_text = $('.jt-tooltip-text').text();
var test_tip = $('<div class="jt-sidebar-tip">').text(tag_text).offset(tag_offset).appendTo('#jt-tooltip-sidebar');
.middlebar {
width: 49%;
float: left;
}
.sidebar {
height: 500px;
width: 49%;
float: right;
border: 1px solid purple;
}
.jt-tooltip-tag {
font-weight: bold;
background-color: #14c9c9;
}
.jt-tooltip-text {
display: none;
}
.jt-sidebar-tip {
position: absolute;
}
