How to move elements using CSS

I want to move the blue icon with the question mark to the bottom of the box right above the paragraph while also moving the gray icon to the top right of the paragraph without messing up my text.
I tried making multiple flex containers but nothing seems to be working.

<div class="button">
<button class="continue">Continue</button>
<button class="cancel">Cancel</button>
</div>
</div>
<link rel="stylesheet" href="style.css">

put the element in the container that you want it to show up in its corner or edge.
then make the parent container position: relative; and your element position: absolute; then control their position using top, right, left, and bottom. here is the code.

How can I display only one section at a time while scrolling vertically on a page?

I am trying to create an effect on a blog page in which the blog posts are displayed as cards, and whenever one scrolls vertically on the page, a card will fade into view and then fade out when the next card is displayed. Something similar to a carousel/image slider but where only one card is visible at the time. At the same time I want the background image to be fixed. A mix between parallax and carousel.
I have tried to set the cards' container to allow overflow-y so that the cards are scrollable, but I do not want the scrollbar to appear either. Honestly, I have looked everywhere for a similar example, but none are close to what I am trying to achieve.
I have found other examples where I can create a parallax effect, but the thing is I only have one background image. I am not sure if I need to use JavaScript as well to try to implement this design. The closest I have come to is ScrollOut, but I do not know how to make only one card visible at the time.

If I understand what you're going for, you could use position: sticky along with an IntersectionObserver to create fade-in/fade-out effects.
A basic implementation of a position: sticky layout could be something like this:
<div class="section__posts--card">
<!-- **** add inner wrapper **** -->
<div class="inner-el">
<img src="https://source.unsplash.com/random/780x200" class="blog-image" alt="">
<h1 class="blog-title">Lorem ipsum dolor sit amet consectetur.</h1>
<p class="blog-overview">Lorem ipsum dolor sit amet consectetur adipisicing elit. Sunt incidunt fugiat quos porro repellat harum. Adipisci tempora corporis rem cum.</p>

</div>
.section__posts {
width: 100vw;
height: 100vh;
position: relative;
}
.section__posts--card {
height: 200vh; // how far the user should scroll before content changes
}
.inner-el {
top: 200px; // how far from the top of the viewport the content should sit
height: auto;
position: sticky;
width: 75vw;
max-width: 50rem;
margin: auto;
}
This is a pretty good 'tutorial' on how to add IntersectionObserver with position: sticky: https://developers.google.com/web/updates/2017/09/sticky-headers

Thanks to organicon's insight about IntersectionObserver I was able to come up with a solution that created the effect exactly as I wanted.
I made the background fixed and turned off overflow for the body.
I wrapped the cards in a container, and turned on the overflow-y BUT I hid the scrollbar using: scrollbar-width: none; -ms-overflow-style:none;
Wrote a script using IntersectionObserver that will track when a card comes into view. When the card appears a CSS animation is applied that fades the card in.
const callback = (entries) => {
entries.forEach(
(entry) => {
if (entry.isIntersecting) {
console.log("the element is intersecting");
entry.target.style.animation = entry.target.dataset.fade;
entry.target.style.opacity = 1;
} else {
entry.target.style.animation = "none";
entry.target.style.opacity = 0;
}
}
);
}
let observer = new IntersectionObserver(callback);
const fadeItems = document.querySelectorAll('.animate');
fadeItems.forEach(item => {
console.log("adding " + fadeItems.length + " cards to the observer");
observer.observe(item)
});

Just do what they do on the page you linked to
You do need an element with the FAS classes - you can give the button that class
Note the CSS to place the button
Also your HTML is invalid. You have too many body tags
#music { position: absolute; top: 10px; right:50px}
<link rel="stylesheet" href="https://ka-f.fontawesome.com/releases/v5.15.4/css/free.min.css?" />
<button id="music" onclick="document.getElementById('player').play()" class='fas'></button>

You mentioned w3example using font-awsome icons to display the icons
You given Example: https://www.w3schools.com/icons/tryit.asp?icon=fas_fa-guitar&unicon=f7a6
Related Font Awsome Icon: https://fontawesome.com/v5.15/icons/guitar
So icon is not display into frontend without calling fontawsome library
I made changes
1st Add font awsome library in to head
<link rel="stylesheet" href="https://ka-f.fontawesome.com/releases/v5.15.4/css/free.min.css?" />
2nd Add fas class to button
<button id="music" onclick="document.getElementById('player').play()"></button>
Changed to
<button id="music" onclick="document.getElementById('player').play()" class='fas'></button>
Please check the following Working code sinppet

how to fix my page from becoming wider using js and css for a parallax

Like I was saying for some reason my screen ends up becoming wider when I scroll. My goal is to be able to click the about me section and it scrolls to the about me section or div. when I do this, however, I see that it is making the sections wider. What is making the section wider is the actual js but I don't know why.

Why doesn't this slider work when I insert it on the website?

I've picked a slider from codepen.io to put on my website, and it doesn't work when I embed it... The four slides that should be separated are all together and the buttons don't work... The same happens when I paste the code in JSFiddle... Can anyone help me, please?
Here is the Fiddle: https://jsfiddle.net/swpch979/

It's using scss as a preprocessor. Convert to regular CSS and it'll work.
