Why is my website's grid collapsing the first time it's loaded?

I'm sorry for dropping so much code here, but I've been playing with this for over a week and I just can't figure it out.
So I am working on my personal website, and the problem is that the images in the the body's grid system overlap sometimes on the first load of the site. If you refresh it, it seems to work ok (most of the time). You can try yourself: tylerteacher.com . The strange thing is that the site works in the compatibility viewers in chrome and firefox.
I have tried adding margins and using the 'space-between' function in the css. I have double checked the html to make sure everything is properly linked to the css page, and I have also played with Javascript page and the slides per view functions.
I really appreciate the help!
let toggle = document.querySelector("#header .toggle-button");
let collapse = document.querySelectorAll("#header .collapse");
toggle.addEventListener('click' , function(){
collapse.forEach(col => col.classList.toggle("collapse-toggle"));
})
// with masonry
new Masonry("#posts .grid", {
itemSelector : '.grid-item',
gutter : 20
});
// swiper libray initialization
new Swiper('.swiper-container', {
direction : 'horizontal',
loop : true,
slidesPerView : 6,
autoplay : {
delay : 0
},
// responsive breakpoints
breakpoints : {
'#0' : {
slidesPerView : 2
},
// 888px
'#1.00' : {
slidesPerView : 3
},
// 1110px
'#1.25' : {
slidesPerView : 4
},
// 1330px
'#1.50' : {
slidesPerView: 5
}
}
})
// Sticky Navigation
window.onscroll = function(){ myFunction()};
// get the current value
let navbar = document.getElementById("header");
// get the navbar position
let sticky = navbar.offsetTop;
// sticky function
function myFunction(){
if(window.pageYOffset >= sticky){
navbar.classList.add("sticky");
}else{
navbar.classList.remove("sticky");
}
}

It is caused by the Masonry. You have to let the page finish loading before you initialize it. This worked for me
window.addEventListener('load', function(){
new Masonry("#posts .grid", {
itemSelector : '.grid-item',
gutter : 20
});
// remove preload if added
});
Optional: Whiles the page loads, you can add a preloader to hide the page's disorganised stucture.

What you're experiencing is due to the Masonry script calculating the dimensions of the grid based on its content. While loading the page your images don't have a width and height because the browser doesn't know what they look like. Masonry doesn't wait and will render your grid anyway.
A fix for this is to let the browser know in advance what the dimensions of the image will be. You can do this by adding a width and height attribute to your img tag containing the width and height in pixels.
<img src="your-image.jpg" class="img-fluid" width="480" height="720" alt="" />
Alternatively you could wait for all images in your grid to load before initializing the Masonry script.
// Loads a single image.
const loadImage = src => new Promise(resolve => {
const image = new Image();
image.onload = () => resolve();
image.src = src;
});
// Get the container with all images.
// Loop over each image and wait for all of them to load.
async function allImagesLoaded(selector) {
const container = document.querySelector(selector);
if (container === null) {
return;
}
const images = container.querySelectorAll('img');
return Promise.all([...images].map(
src => loadImage(src)
));
}
// Load all images inside #posts .grid.
allImagesLoaded('#posts .grid').then(() => {
new Masonry("#posts .grid", {
itemSelector : '.grid-item',
gutter : 20
});
});

Change Carousel active indicator as it scrolls or is selected

I have build a boostrap Carousel and modified the indicators to be the map markers with icons in the middle. They rollover fine, but what i was hoping to add is when the corresponding slide below is active they show the hover state.
http://women.hemophilia.on.ca/
What is tied so far is adding the class, as it scrolls, Carousel automatically changes the active class to each item
.marker-recently:hover, .marker-recently .active{
background-image:url(/wp-content/uploads/2021/11/marker-recently-over.png);
}

You already did it right in your CSS sheet, but you just wrote it wrong.
You wrote:
.marker-concerns:hover, .marker-concerns .active
so you are sniping an element with class active as a child of element with class marker-concerns (which it does not exist). Remove the space so when you call:
.marker-concerns.active
You are actually calling an element with BOTH classes (which is what you need).
Remove the blank space from all six css lines ans it should work.

How to create a polling system in HTML for a movie review website?

How do I creating a voting system that uses checkboxes for 1 star, 2 stars, 3 stars, 4 stars and 5 stars. According to what the user picks it will generate an average user rating from the given votes and display the number of stars required.
I am not sure where exactly to start in terms of gathering the input from the user etc...This is all the code I have for now

Usually a 5-star polling system will require a database and a backend programming language. i.e. Mysql and PHP.
Here is an example:

How do I get this Anchor tag to fill the space before the next div?

I have been trying to create a bootstrap drop down box with some additional buttons inside. I have the main functionality sorted but the aesthetics are not quite right.
The issue I am having is that the Anchor elements are not filling the space up to the buttons on the right. I have tried experimenting with different combinations of block and inline-block which I have read elsewhere should fill the space but when it does it pushes the buttons down to the next line. When I do manage to get the buttons and anchor elements on the same line the selection area for the anchor does not extend the entire way up to the buttons.
I am currently tearing my hair out trying to get it to work but am having no luck so if anyone can offer any assistance it will be greatly appreciated.
Update:
Thanks to #Matus Jurika for suggesting using calc to adjust the sizing of the anchor element.
Updated working fiddle: fiddle

I sugget using calc for width:
.anchorDiv {
display: inline-block;
width: calc(100% - 74px);
}

This should do the trick.
.comboItemContainer {
width: 100%;
position: relative;
}
.anchorDiv {
display: inline-block;
width: 100%;
padding: 0 80px 0 0;
}
.comboButtons {
width: 74px;
display: block;
position: absolute;
top: 0px;
right: 0px;
}
I made the container relative so that I can freely use absolute positioning on its children with a (0,0) origin relative to the container. Then I made the buttons absolute, made it top 0 and right 0. Added 100% width on the anchor and 80px padding-right.
This may look hacky but I'm not really that good in Flex and absolutely zero in Grid
This is almost certainly cross browser though

Javascript/Jquery - Target closest relevant block to show content in a stream of similar cards

I have a set of cards. Here is the DEMO.
even if i only put 3 cards in the demo i have an infinite number if cards in the real app.
When you hover on the first card, and then click on the "plus" icon that appears, a block of info covers the whole card and show info specific to this card.
What I don't manage to do is: when a user clicks on the "plus "icon of any card, like the second, third ...the user should see the info of this card appear (just like it does for the first card).
Constraint:
I could indeed put a number for each card like id "#card345", "#card567" and so on, and use javascript to put this variable id inside the javascript script to only target this id number.
For performance reasons, I would like not to do it this way, that is to say not use any VARIABLE such as the id of the card inside the javascript code. and only use a jquery/javascript code to target the "closest" block to show. I heard of "closest" or next() but I don't manage to do it. I'm open to any css or javascript/jquery solution.

Why don't use the closest() function?
Here's the docs.
Something like
$("#plusbutton").click(function(e){
$(e.target).closest('.card').find('.info-overlay').show();
}
And beside the code, I would strongly suggest you not to use IDS, use classes instead for elements names, since they're not unique.
Also, for the opposite reason, do not use the card ID as a class: use an ID here (if you really need the card ID). And remember that you shouldn't use only the number. Better something like: id="card-353"
Take a look:

I've just edited your fiddle, if I understand your question, now it works properly.
Still, please clean up your html code :)
