Show buttons on a div element onhovering as an overlay

i am having a div element which displays a chart.my aim is to show a blurred overlay on hovering the chart and show a set of butttons.
my div
<div className='col-lg-3 card-container3'>
<div className="card-content2">
<BarCharts chartLabel='daily' handleZoom={handleZoom} data={data} options={data.options?data.options:options_flights}/>
</div>
</div>
the related css
.card-container3 {
border-radius: 10px;
box-shadow: 0px 2px 2px rgba(0, 0, 0, 0.14), 0px 3px 1px rgba(0, 0, 0, 0.12), 0px 1px 5px rgba(0, 0, 0, 0.2);
#include myTheme.theme-aware('border-color', 'cardBorderColor');
#include myTheme.theme-aware('background', 'cardContentColor-bg');
width: calc((100% - 5%) / 3);
min-height: 230px;
margin: 0 .5rem 1.5rem 0;
#extend .white;
padding: 0px 25px 2px 25px;
display: flex;
justify-content: center;
}
.card-content2 {
display: grid;
justify-content: flex-start;
align-content: center;
min-height: 200px;
.card-icon-block {
padding: 0 0 20px 0;
img {
/* height: 47px;width: 47px; */
height: calc(0.9rem + 2vw);
width: calc(0.9rem + 2vw);
}
}
i have tried
.card-content2:hover{
background-color:'#6f42c1';
border: 1px solid #ddd;
}
i was able to get the hover effects by applying this any suggestions in adding buttons on hover in the element?
my UI should be looking like this in a before after perspective

In the browser inspector, try to find a selector for these buttons, and use this selector to show the buttons on hover.
For example, if the buttons have a class called button-class.
.card-content2:hover {
background-color:'#6f42c1';
border: 1px solid #ddd;
.button-class {
display: inline; // if `display: none`
visibility: visible; // if `visibility: hidden`
opacity: 1; // if `opacity: 0`
}
}

is it possible for a function to connect to another function and gather information from an array JS

is it possible to make a function that is connected to another function that has an array this is a JS game Red Light Green Light the array is holding the text "Green Light, Red Light" I want to know if its possible to make another function that is taking information from my characters movement and when the green light or red light text appears for exapmple when green light appears nothing happens because its safe to move but when red light it appears you fail and a game over screen appears
var colors = ['Green light', 'Red light'];
(function () {
var words = ["Red light"]
i = 0;
setInterval(function(){ $('#words').fadeOut(function(){
$(this).html(colors[(i = (i + 1) % colors.length)]).fadeIn();
}); }, 4000)
})();
$(document).ready(function(){
var Block = function()
{
this.goalDistance = 1370;
this.distanceTraveled = 0;
go = false;
}
var block = new Block();
$('#green-button').click(function(){
console.log('GO!');
block.go = true;
animateBlock();
// this allows the block bob to move forward
});
$('#red-button').click(function(){
console.log('STOP!');
block.go = false;
// this allows the block bob to stop moving
});
function animateBlock()
{
if(block.go === true && block.distanceTraveled < block.goalDistance)
{
$('#block').animate({left:'+=10'},50);
block.distanceTraveled += 10;
setTimeout(function(){
animateBlock();
},50);
}
}

How do I get my etch-a-sketch program to "listen" to this dropdown menu instead of the buttons?

I'm new to Stack Overflow. I hope that I'm doing this correctly. ❤
I'm working on an old Etch-a-Sketch JavaScript project from months ago and decided to rework the 'mobile' form of the project because I hadn't bothered to do so at the time. At first, I tried just moving the buttons to the top horizontally, but I didn't like any of the variations I tried. So I decided I'd be better off with a dropdown menu instead that would appear when the screen is 500px or smaller, replacing the buttons.
The dropdown menu is supposed to do exactly what the buttons do - when a certain mode is selected, that's the mode that the program is supposed to switch to. For example, when the "Party mode" button is clicked, the program switches to "party mode". I want the dropdown menu to behave similarly - when the "party mode" option is selected, the program should switch to "party mode".
My logic was that I needed a function that grabbed the value of the dropdown menu, and then an "if" condition would run that pretty much says "If the value is x, x mode should run; else if the value is y, y mode should run", and so on. I added the function to the existing window.onload function so it would run upon the window loading. This didn't work.
Note that the dropdown menu will, in the future, only appear when the screen size is 500px or less. In addition, I still have the buttons on the screen for all sizes, just for testing/debugging purposes. When I'm done and have this figured out, the buttons will have "display = 'none'" and be hidden for the "mobile size".
Anyway, so yeah, the program is still just listening to the buttons, and not the dropdown menu. That leads me to believe that I need to somehow turn "off" the button mode? If that's the case, how do I do that? If that's not the case, what am I supposed to do here? Any help or insight would be greatly appreciated. Thanks!

Luckily, there's an easy way to do that. Add this piece of code into your javascript file and see the magic.
const dropdown = document.getElementById('dropdown-mode');
dropdown.addEventListener('change', (e) => {
setCurrentMode(e.target.value);
});

Transition from right to left

I need to change some background color with a smooth transition from right to left instead of just changing the color in a uniform way. I will now provide you my code, so that maybe it will be more clear.

I am sorry if my explanation appears poor: I'll be happy to answer your doubts.

You could do it very simply with css transition. This method work on :hover. Working CodePen.

Javascript Stop Propagation

I have been trying to figure out how to get an index of a dynamically created element so that I can write a function to delete it (splice).
I have figured out how to get the index really manually, but the problem is that I am getting Propagation from my event delegation and I am not sure how to stop it.
I have tried putting stopPropagation(), preventDefault(), stopImmediatePropagation() at various points within the function and have spent the last hour reading around online trying to figure out how to stop it. I even tried setting the e.bubble to false with no avail.
Could someone point me in the right direction here? Im sure its my inexperience but I am just out of ideas as of now.

// I need to create a function that upon submit of a guess, checks its value against the answer textContent.
// I will likely need to make the text lowercase for the check to just make sure that they match exactly and that a capital letter wont create a false when its true.

I am wanting to figure out how to delete an item from the list
How about we change the last line of the function createDisplayItem to ..
function createDisplayItem(){
...
return newUl.appendChild(trashCan) // Added return
}
Now, you have an instance of the newly created trash can element being returned to the calling code, so now all we have to do is add a click event to this specific trash can element and let it delete its parent ul ..
submit.addEventListener("click", function() {
...
let trashCan = createDisplayItem();
trashCan.addEventListener('click', function(){
confirm('Are you sure you want to delete this?')
&& this.parentNode.remove()
})
...
});
So, since now in this code, each trash can takes care of its own parent element, you do not have to worry about finding the index from the parent display element anymore.
