How do I center align?

https://github.com/ProjectCubit/website.git
I have a little problem that I just cannot seem to solve.
How do I center align? I tried various methods, but nothing seem to work.
I tried position: absolute, flex, and other methods from W3. Sorry, if this seems like a silly question.
I'm a bit new to Programming, thanks.

You can use text-align: center;, and <br> if you want. Here's a snippet:
.text {
text-align: center;
position: absolute;
width: 450px;
left: 50%;
margin-left: -225px;
height: 40px;
top: 50%;
margin-top: -20px;
}
p {
display: inline-block;
vertical-align: top;
margin: 0;
}
<div class="text">
<p>Nachos are</p><br/>
<p>
<span>tasty.</span><br/>
<span>wonderful.</span><br/>
<span>fancy.</span><br/>
<span>beautiful.</span><br/>
<span>cheap.</span><br/>
</p>
</div>
Here it's all in one line:
.text {
text-align: center;
position: absolute;
width: 450px;
left: 50%;
margin-left: -225px;
height: 40px;
top: 50%;
margin-top: -20px;
}
p {
display: inline-block;
vertical-align: top;
margin: 0;
}
<div class="text">
<p>Nachos are</p>
<p>
<span>tasty.</span>
<span>wonderful.</span>
<span>fancy.</span>
<span>beautiful.</span>
<span>cheap.</span>
</p>
</div>

If you want to align inline all in one line, and center it in the middle of the page
you can use flex to your parent only;
.text {
display:flex;
justify-content: center;
align-items:center;
}

I checked out your code & it centers after adding text-align: center to .text.
Adding flex to .text does not work for the following reason:
The 2nd <p> containing the span.word has 0 width & height, due to its children being absolutely positioned. In order for flex to work you need to set appropriate width & height to the 2nd <p>.
But text-align: center unlike flex is inherited by all descendants, and not just the children.

How to show text on an image? (code is in question)

I am trying to learn coding in my freetime and have run into an issue. I am trying to have 'contact info' to be a on hover on profile picture so that it shows a way to contact me via phone, email, and shows my name. I'm hoping someone can help with this please.
Cut most of the HTML code in the process to allow post
var infoDivs = document.getElementsByClassName ('infoDivs');
var contactInfoDiv = document.getElementById('contactInfo');
function displayInfo(index) {
for (var i = 0; i < infoDivs.length; i++) {
infoDivs[i].style.display = 'none';
}
infoDivs[index].style.display = 'block';
}
function showcontactInfo() {
contactInfoDiv.style.display = 'block'
}
function hidecontactInfo() {
contactInfoDiv.style.display = 'none'
}
//line 12-18 is what should be my issue? Otherwise line 2? //

The solution I decided on is simple enough, I add a class to know which piece of text I'm currently editing, and then set the color CSS attribute to the colour picker's selection for that selected class.
So your onclick is now:
var onclick = 'onclick="editTextColour(this)"';
I made a new function to handle the basics, (this) as the param for onclick is treated as the element that calls it:
function editTextColour(elem) {
$('.editing').removeClass('editing');
$(elem).addClass('editing');
$('.edit-block').show();
}
And then your change event for the color picker is just this:
$(".color").on("change", function() {
var colorValue = $(".color").val();
$('.preview .editing').css('color', colorValue);
});
JSFiddle

Fit an element according of another element

I am trying to fit two divs around the header-title, but I can't seem to get it to work. I'm not sure that the calc() works well with the javascript. Here is the code so far:
document.getElementByClass('Header').clientWidth;
:root {
--main-accent-color: #3500D3;
--main-bg-color: #282828;
--secondary-bg-color: #0c0032;
--main-content-bg-color: #190061;
--text-color: #ffffff;
--alt-color: #240090;
}
* {
box-sizing: content-box;
margin: 0;
}
body {
background-color: var(--main-bg-color);
}
h1 {
font-family: robot0, sans-serif;
font-size: 70px;
font-weight: 100;
font-variant: petite-caps;
color: var(--text-color);
}
.header {
background-color: var(--main-bg-color);
width: 100%;
height: 100px;
top: 0;
margin: 0;
position: fixed;
text-align: center;
z-index: 10;
border-bottom: 5px solid var(--main-accent-color);
}
.header-title {
box-sizing: content-box;
background-color: var(--main-bg-color);
height: 85px;
width: 500px;
margin: auto;
vertical-align: middle;
padding-top: 50px;
padding-top: 20px;
border-left: 5px solid var(--main-accent-color);
border-right: 5px solid var(--main-accent-color);
z-index: 11
}
.header-info {
width: calc((clientWidth - 500) / 2);
height: 100px;
display: inline-block;
position: absolute;
margin: 0;
padding: 0;
}
#right-info {
right: calc(((clientWidth - 500) / 2) + 500);
}
#left-info {
right: 0;
}

If there is another method that I can use, that would be great. Also, I am learning CSS right now, so I am not confident with JavaScript at all, I only used it because that's how other people did it.

I think you are making it too complicated. I removed a lot of code and added flexbox for the header. Both divs at the side are allowed to grow as much as space allows.
:root {
--main-accent-color: #3500D3;
--main-bg-color: #282828;
--secondary-bg-color: #0c0032;
--main-content-bg-color: #190061;
--text-color: #ffffff;
--alt-color: #240090;

background-color: var(--main-bg-color);

}

height: 100px;
top: 0;
position: fixed;
border-bottom: 5px solid var(--main-accent-color);
display: flex;
align-items: center; /* Vertical alignment */
}
.header-title {
width: 500px;
border-left: 5px solid var(--main-accent-color);
border-right: 5px solid var(--main-accent-color);
text-align: center;

How to reset JavaScript random number generator

I’ve started my first own JS project.
In the end, I would like to have my own slotmachine.
By now, I’ve the problem, that I don’t know how to restart my program or just the function for generating again and again the new random values.
This is my code until now:
var randomX1 = Math.ceil(Math.random() * 10 );
var randomX2 = Math.ceil(Math.random() * 10 );
var randomX3 = Math.ceil(Math.random() * 10 );
function randomClickX() {
document.getElementById("randomX1").innerHTML = randomX1;
document.getElementById("randomX2").innerHTML = randomX2;
document.getElementById("randomX3").innerHTML = randomX3;
var ausgabe = "Play again";
if (randomX1 === randomX2) {
if(randomX2 === randomX3) {
var ausgabe = "Jackpot";
}
}
var chance = ausgabe;
function clickChance() {
document.getElementById("chance").innerHTML = chance;
}
document.getElementById('spanId').innerHTML = chance;
};
.slot-container {
border: 5px solid red;
vertical-align: middle;
font-size: 50px;
font-family: Leelawadee UI Semilight, Calibri, Arial;
width: 90%;
margin: auto;
height: 0;
padding-bottom: 30%;
}
.slot {
border: 3px solid green;
height: 0;
padding-bottom: 30%;
width: 32%;
margin-right: 1%;
margin-top: 1%;

As you see, I've to reload the HTML file to click the SPIN-button again to have new randoms.
I think the point is to create a big comprehensive function and call it when the SPIN function ends. But I don't now how to do that ...
What is the missing step, to have as many values as the user wishs to have?
Thanks, Jonas

Simply move the random numbers being generated into the click method.
function randomClickX() {
var randomX1 = Math.ceil(Math.random() * 10 );
var randomX2 = Math.ceil(Math.random() * 10 );
var randomX3 = Math.ceil(Math.random() * 10 );
document.getElementById("randomX1").innerHTML = randomX1;
document.getElementById("randomX2").innerHTML = randomX2;
document.getElementById("randomX3").innerHTML = randomX3;
var ausgabe = "Play again";
if (randomX1 === randomX2) {
if(randomX2 === randomX3) {
var ausgabe = "Jackpot";
}
}
var chance = ausgabe;
function clickChance() {
document.getElementById("chance").innerHTML = chance;
}
document.getElementById('spanId').innerHTML = chance;
};
