how to remove whitespace below div element - javascript

I have some divs and among them there's a small gap or whitespace.
I have tried changing margin top and bottom but it is not working. I think it's something to do with the image but I have not found a solution yet.

There is a ` character in html, which makes extra space.


You have a ` between those divs
Replace those divs with this
<div id = "header-bg">
<div id = "header-wrapper">
</div>
</div>
<div class = "details-wrapper">
</div>


remove height from #header-bg. You set 590px for the height.

Poistioning and display:flex does not well together.
If you want to use position:absolute on the flexed container apply position:absolute on #header-bg,it is because of that you have the white space

Photography is life.
</h2>
<br><br><br>
<p>Wildlife photography is one of the most exciting photographic genres out there. But it can be difficult to get started as a wildlife photographer because of all the gear, technical know-how, and additional knowledge required.In the early days of photography, it was difficult to get a photograph of wildlife due to slow lenses and the low sensitivity of photographic media. Earlier photos of animals were often captive animals. These included photos of lion cubs taken at the Bristol zoo in 1854 and in 1864, photos of the last Quagga by Frank Hayes. Wildlife photography gained more traction when faster photography emulsions and quicker shutters came in the 1880s. Developments like these lead to photos such as the ones taken by German Ottomar Anschutz in 1884, the first shots of wild birds in action. Members of the Delaware Valley Ornithological Club (DVOC) captured early photographs of nesting songbirds in the Philadelphia area in 1897.In July 1906, National Geographic published its first wildlife photos.The photos were taken by George Shiras III, a U.S. Representative from Pennsylvania. Some of his photos were taken with the first wire-tripped camera traps.</p>

<h2>
Photography is life.
</h2>
<br><br><br>
<p class="m-0">Wildlife photography is one of the most exciting photographic genres out there. But it can be difficult to get started as a wildlife photographer because of all the gear, technical know-how, and additional knowledge required.In the early days of photography, it was difficult to get a photograph of wildlife due to slow lenses and the low sensitivity of photographic media. Earlier photos of animals were often captive animals. These included photos of lion cubs taken at the Bristol zoo in 1854 and in 1864, photos of the last Quagga by Frank Hayes. Wildlife photography gained more traction when faster photography emulsions and quicker shutters came in the 1880s. Developments like these lead to photos such as the ones taken by German Ottomar Anschutz in 1884, the first shots of wild birds in action. Members of the Delaware Valley Ornithological Club (DVOC) captured early photographs of nesting songbirds in the Philadelphia area in 1897.In July 1906, National Geographic published its first wildlife photos.The photos were taken by George Shiras III, a U.S. Representative from Pennsylvania. Some of his photos were taken with the first wire-tripped camera traps.</p>

JS for visibility effect not working with addeventlistener

Skimmed through similar questions but didnt quite get the answer im looking for. I have an <a> that I want to be visible when hovering another <a>. I know my code is getting messy but still wanna know if this is doable. I tried with addeventlistener, which I thought would work, but it does absolutely nothing, is something missing from my js?
document.getElementById("defaultlang").addEventListener("mouseover", mouseOver);
document.getElementById("defaultlang").addEventListener("mouseout", mouseOut);
function mouseOver() {
document.getElementById('secondlang').style.visibility = "visible";
}
function mouseOut() {
document.getElementById('secondlang').style.visibilty = "hidden";

You can do this with plains css
#defaultlang:hover ~ #secondlang {
visibility: visible;
}
#secondlang {
visibility: hidden;
}
~ selects all the siblings of #defaultlang. You can use + to select only the adjacent sibling.

Why doesn`t work my popup, although I connect Js?

Yesterday I made a popup in Html, Css and JS but it didn`t work.
Javascript is connected with the Html file, the button can you see on the header everytime, but I`ll that when I click on the button "Codes" that a popup open...
In a other project from me the popup works with the same code...
What shall I do that it works? Or what is the mistake in the code?

document.getElementById("popup").classList.toggle("active");

First and foremost your id attribute is "popup" and in your CSS rules is "pop-up".
Then in your CSS rules, you use the class "open" to show the popup, but in the JS you use "active".
So to work properly you should change the following:
function togglePopup() {
document.getElementById("popup").classList.toggle("open");
}
Then change:
<div class="popup" id="pop-up">
<div class="overlay"></div>
<div class="content">
<div class="close-btn" onclick="togglePopup()">×</div>
<h1>title</h1>
</div>
</div>

Why is my modal opening on the bottom of page?

I have built a modal and inserted it into my code, however whenever I press the button that is supposed to open it up it goes to the bottom of the page. It is supposed to be on top of the rest of the page with a blurry bg, per say, but it just goes to the bottom of the page and it isn't even properly formatted. Here is an image.
Here is the code for that, the navbar and their css, and the modal js file.

height: 100%; /* ...and height to 100%, so that the element fills the entire page */
z-index: 99999; /* set the z-index to a high enough number so that this element is positioned on top of all other elements */
background: rgb(0, 0, 0, 0.7); /* set the background to black with some transparency, so you can see through it */
/* The following simply centers the modal within this container */
display: flex;
justify-content: center;
align-items: center;
}
Now this is the modal.js, what controls the modals functions.
//Get the modal
var modal = document.getElementById("myModal");
var modal_container = document.getElementById("modalContainer")
modal_container.style.display = "none";
window.onclick = function (event) {
console.log(event.target)
if(event.target.id == "myBtn") {
modal_container.style.display = "flex"
}
else if (modal !== event.target && !modal.contains(event.target)) {
modal_container.style.display = "none";
}
}

You set an event handler for all links with href starting with '#' to scroll smoothly into view, but the href of the button that activates your modal windows is "#ex1". There is no "ex1" section in the document, which causes the script error.
A quick solution is to remove "#ex1" from the href attribute.
<a class="cta" rel="modal:open" href="" key="login" id="myBtn">Acessar</a>

How do I center my buttons on my website?

I'm having a problem with my code and can't figure it out. I'm writing my own website and can't get my buttons to go to the center of the page. I tried almost everything I think but it always goes to about 30% or 70% for some reason... The website is not fully responsive for now I will work on that later. What's wrong with my code? What can I do to fix it next time? Thanks for any ideas!

var navList = document.getElementById("nav-lists");

}
const body = document.querySelector('body')
const twitter = document.querySelector('.twitter')
twitter.addEventListener("mouseover", function () {
body.classList.add('linked')
},false)
twitter.addEventListener("mouseout", function () {
body.classList.remove('linked')
}, false)

Seems like you've got it half using flex, here's an answer sticking to it.
Firstly, you spelt buttonbkg wrong. Add flex-direction: column to it. Then like others said you will want to get rid of the left: 50%. On your .steam add your flex, and center align/justify.
.buttonbkg{
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
width: 100%;
height: 90vh;
}
.button {
width: 320px;
max-width: 100%;
overflow: hidden;
position: relative;
transform: translatez(0);
text-decoration: none;
box-sizing: border-box;
font-size: 130%;
font-weight: normal;
font-family: 'familiar_probold';
color: #B9CDBE;
box-shadow: 0 9px 18px rgba(0,0,0,0.2);
display: inline-block;
margin: 3%;
align-content: center;
}
.steam{
text-align: center;
border-radius: 50px;
padding: 26px;
color: white;
background: #BD3381;
transition: all 0.2s ease-out 0s;
display: flex;
justify-content: center;
align-items: center;
}

You need to add this to your button selector:
.button {
transform: translateX(-50%);
}

On your .button class you have left: 50%;, remove it. Also add margin: 3% auto
On you .steam class change display: inline-block; to display: block;
margin: 3% auto
3% -> top/bottom margin
auto -> left/right margin, auto will make left an right margin the same
Other solution would be to change your transform: translatez(0); to transform: translateX(-50%);, but I think transform is like shooting with a shotgun at a fly.
