How to hide overflow on a carousel slider and set a loop

How to hide overflow on a carousel slider and set a loop - javascript

Here is the fiddle link
Hi !
I have a carousel slider and I want to hide the overflow outside the grey box (see the fiddle) and I would like the first button (the first div inside) to come back when the last one is gone.
I am really note familiar with carousel and if someone have a basic lesson on that topic I would apreciate it. I am familiar with css but it feels like the carousel isn't working the same way. I hope this is not duplicated I didn't find a lot about carousel on stack.
$(document).ready(function(){
$('.slider').slick({
infinite: true,
slidesToShow: 3,
slidesToScroll: 1
});
});

background-color: #a6a6a6;

EDIT : My basic problem was coming from my link to code in the css plug-in.
Like one of the anwser told me, I need absolutely the slick.css file in order to make it work and I can or not add the -theme file. Those css sheet hide the overflow without hidding the arrow.
See those file here :
There is the first one (slick.css)

After this, I still have one probleme : The slider buttons just dont show up.
I tried to hide my CSS code with /* */ and yes, the slider button appear but in a weird way.
This is the picture of what happen

To hide the overflow, add overflow: hidden; to #background_etape2 in CSS.
About the circular permutation you want to achieve, it takes a bit more work to do. I'd suggest to use existing jQuery plugins which offer good solutions. Just Google 'carousel javascript' and you'll find some good and well documented examples free to download and use.
Gaby's proposal seems to be the answer.

You have a couple of issues
The most important is that the link to the slick CSS file is wrong. Use //cdn.jsdelivr.net/jquery.slick/1.6.0/slick.css (and add the -theme file if you want to use the plugin theme)
You use duplicate ids on the slides and the links inside. (on the demo i changed those to classes)
See updated demo
$('.slider').slick({
infinite: true,
slidesToShow: 3,
slidesToScroll: 1
});
#import url('//cdn.jsdelivr.net/jquery.slick/1.6.0/slick.css');
#import url('//cdn.jsdelivr.net/jquery.slick/1.6.0/slick-theme.css');
#background_etape2 {
background-color: #a6a6a6;
width: 100%;
height: 500px;
}
#liste_categorie_sondage {
margin-left: auto;
margin-right: auto;
height: 200px;
width: 600px;
background-color: #555;
border: 1px solid black;
position: relative;
top: 150px;
}
.categorie_sondage {
display: block;

padding: 8px 16px;
list-style-position: inside;
display: table-cell;
font-size: 20px;

}
.menusondage {
text-decoration: none;

text-align: right;
padding: 8px;
display: table-cell;
border: 2px solid black;
}
.menusondage:hover {

color: white;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

</div>
</div>
(and the updated fiddle: https://jsfiddle.net/gaby/eaotmar3/14/)

Hiding the overflow
It is really simple just add overflow: hidden to the gray box (#liste_categorie_sondage)
#liste_categorie_sondage {
overflow: hidden;
margin-left: auto;
margin-right: auto;
...
}
But that is not the problem, you are actually not implementing the CSS provide with the plugin. More below
Slider
Your CSS is all wrong and missing and if you are already using a plugin you have to include all the assets and fallow the docs.
Here is a JSFiddle how it should be implemented
Other Mistakes
You are using ID's to style your content which is a BIG no and mistake.
ID's must be unique it is specified ind W3 Docs
This attribute assigns a name to an element. This name must be unique in a document.
Also they will give you a CSS specificity headache, because they are second highest (right after inline declaration)

I am having a little problem with my code.
I want when the user clicks on any button it changes its color to the hover color and text color to white.
And when the user click the next button the previous one will come back to its previous state. Is it possible?

<div class="col-1"><div class="button" id="button-3"><div id="circle"></div>Day Sheet</div></div>
</div>

Just add some rules for the "active" state.
Also, I changed all your IDs to classes. You should only provided unique identifiers in the ID attribute.
Furthermore, I changed the button-3:hover .circle rule to button-3:not(.active):hover .circle. This hides the animation of the circle when hovering over "active" buttons.
.button.active {
background-color: #396;
}
.button.active a {
color: #FFF;
}
.button-3:not(.active):hover .circle {
width: 200%;
height: 500%;
opacity: 1;
top: -70px;
left: -70px;
}
Then listen for the click, toggle the "active" class from all buttons:
Array.from(document.querySelectorAll('.button')).forEach(button => {
button.classList.toggle('active', button === e.currentTarget);
}
Example
Array.from(document.querySelectorAll('.button')).forEach(button => {
button.addEventListener('click', handleButtonClick);
});
function handleButtonClick(e) {
Array.from(document.querySelectorAll('.button')).forEach(button => {
button.classList.toggle('active', button === e.currentTarget);
});

Add/Remove class to get a menu to display

I started programming the mobile version of my nav menu earlier. I had to rework my #serviceNav to get it to work in a mobile setting. When doing this I changed my javascript from this:
/*$('#serviceClick').click( function () {
$('#serviceNav').addClass('activeSol');
});*/
$('[data-pop-close]').on('click', function(e) {
//var targeted_pop = $(this).attr('data-pop-close');
$('#serviceNav').removeClass('active');
$('body').css('overflow', 'auto');
e.preventDefault();
});
To this:
$('#serviceClick').click(function() {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('.activeSol').removeClass('activeSol').next('#serviceNav').slideUp(500);
relative.addClass('activeSol').next('#serviceNav').slideDown();
//$('.infoTitles:before').addClass('opened');
} else {
relative.removeClass('activeSol').next('#serviceNav').slideUp(500);
}
return false;
});
The issue that I am having now that I previously didn't with my javascript code is that now my desktop media query version of my #serviceNav is not displaying, however it does display and function in the mobile setting. The trigger for this menu is the menu item called "Solutions". You can see that in a media query over 640px that nothing happens, but 640px or less it applies the fadeDown function.
Does anyone see why this is not working for the larger version media query?
Here is a jsfiddle
Full code:
$('#mobile-button').on('click', function () {
$('#nav-pop').addClass('active');
$('html').addClass('is-navOpen');
});
/*$('#serviceClick').click( function () {
$('#serviceNav').addClass('activeSol');
});*/
$('#serviceClick').click(function() {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('.activeSol').removeClass('activeSol').next('#serviceNav').slideUp(500);
relative.addClass('activeSol').next('#serviceNav').slideDown();
} else {
relative.removeClass('activeSol').next('#serviceNav').slideUp(500);
}
return false;
});

There is a lot going on here and frankly, it's hard to decipher but I think "Nothing happens" is relative. When inspecting the element in dev console you can see the Javascript styling is being added appropriately. So something is happening, it's simply happening off screen because you've told it to. I think the culprit here, is the >640px positioning of your #serviceNav element is maintained at top: -40vh; That's a lot. When removing this value the button displays as follows:
Note: you will have to change some other things around as this displays it on page load. But you get the idea

Click function never reading else statement to remove class

I have been stuck on a sliding down menu, but have made some headway with it. I had to modify a lot to make it work for both desktop and mobile viewports. The only thing I am stuck on now is getting the menu to close in a < 640px viewport.
In my snippet and jsfiddle below there is a lot of code, but the only code that really matters to this question is the javascript below:
$('#serviceClick').click( function () {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else {
$('#serviceNav').removeClass('activeSol').slideUp(500);
}
return false;
});
Basically my else statement is now removing the class 'activeSol` and then sliding up the selection.
In the mobile viewport, after clicking on "Solutions" the menu expands, but when you click on "Solutions" again, nothing happens.
It seems as if the variable relative is never reading as the class appended to it, making the click function run else. I did a simple console.log and the else never runs. I tried changing the click function to a change, but then the menu never triggers.
Does anyone see what is causing my else statement to not removeClass from serviceNav and slideUp?
JSfiddle link to see in mobile viewport.
$('#serviceClick').click( function () {
var relative = $(this);
if (!relative.hasClass('activeSol')) {
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else {
$('#serviceNav').removeClass('activeSol').slideUp(500);
}
return false;
});
$('[data-pop-close]').on('click', function(e) {
//var targeted_pop = $(this).attr('data-pop-close');
$('#serviceNav').removeClass('activeSol');
$('body').css('overflow', 'auto');
e.preventDefault();
});

var relative = $(this);
Is picking the serviceClick list item (li) and then you are checking
if (!relative.hasClass('activeSol')) {
but you never added the class to the li, instead you added it to the div #serviceNav.
I think changing
if (!relative.hasClass('activeSol')) {
to
if (!$('#serviceNav').hasClass('activeSol')) {
should work.

Your shouldn't check for $("#serviceClick") for class activeSol, should check on $("#serviceNav") instead.
if (!$('#serviceNav').hasClass('activeSol')) {
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else {
$('#serviceNav').removeClass('activeSol').slideUp(500);
}

relative doesn't have the class 'activeSol' and will never have it, in order to have it toggle the visibility of your menu, you should add and remove classes to it, like this:
$('#serviceClick').click( function () {
var relative = $(this);
if (!relative.hasClass('opened')) { // if it's not opened
relative.addClass('opened'); // open it
$('#serviceNav').removeClass('activeSol');
$('#serviceNav').addClass('activeSol').slideDown();
} else { // if it's opened
relative.removeClass('opened'); // close it
$('#serviceNav').removeClass('activeSol').slideUp(500);
}
return false;
});

Change text colour based on background

I have a CTA that slides out when you hover over it. The problem I have is that the text is sometimes hard to read depending on the background colour. I've created a demo of what I'm trying to achieve, you can check it out here:
Demo on CodePen
The essence of this demo is:
HTML:
<div class="at-about-fab">
<div class="at-about-fab__thumbnail">
<img alt="Fiat Professional" src="https://fiatprofessionaleastlondon.co.za/wp-content/uploads/2018/02/CallUs.png" />
</div>
<div class="at-about-fab__meta">
<h2>Call Us Now</h2>
<p>555 555 5555</p>
</div>
</div>
The CSS looks like this:
.at-about-fab {
z-index: 999999;
position: fixed;
right: 20px;
bottom: 20px;
display: flex;
align-items: center;
flex-direction: row;
transform: translateX(100%);
transition: 0.2s ease;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
&:before {
content: "";
position: absolute;
display: block;
top: 50%;
left: -58px;
width: 58px;
height: 48px;
transform: translateY(-50%);
}
&:hover {
transform: translateX(0%);
.at-about-fab__meta {
opacity: 1;
}
}
&__thumbnail {
position: absolute;
top: 50%;
left: -58px;
background: #FFFFFF;
width: 48px;
height: 48px;
border: 1px solid #EEEEEE;
border-radius: 100%;
padding: 4px;
box-sizing: border-box;
transform: translateY(-50%);
overflow: hidden;
cursor: pointer;
img {
display: block;
width: 100%;
border-radius: 100%;
}
}
&__meta {
font-family: 'Open Sans', sans-serif;
opacity: 0;
transition: 0.2s ease;
h2,
p {
margin: 0;
padding: 0;
}
h2 {
color: #444444;
font-size: 14px;
font-weight: 600;
}
p {
color: #CCCCCC;
font-size: 12px;
font-weight: 400;
}
a {
color: inherit;
font-weight: 400;
text-decoration: none;
}
}
}
Any suggestions on how to get this right? I've looked at a few JavaScript-based examples but my JavaScript skills aren't there yet...
Many thanks

You can try something like this:
Idea
Add mouseover event on main container.
In this handler, have a variable that will hold classname that is to be added.
On hover:
Get all sections.
Check the bounds of current section with icon's bound.
If top of icon is greater than top of section, update the className variable
If not, break the loop.
Now remove all classes add className to container. You will also have to write corresponding classes in CSS as well.

var iconContainer = document.querySelector('.at-about-fab');
iconContainer.addEventListener('mouseover', function () {
var bounds = this.getBoundingClientRect();
var sections = document.querySelectorAll('.section');
var className = '';
Array.from(sections).some(function(el) {
var currentBounds = el.getBoundingClientRect();
if(bounds.top > currentBounds.top) {
className = el.getAttribute('id');
}
else {
return true;
}
});
this.classList.remove('section1', 'section2', 'section3', 'section4');
this.classList.add(className);
})

Centering an image within a slick slider

I have set my images so that they overflow the div that contains them which is exactly what I want, but I want the images to be centered vertically on all browsers at the moment them just overflow at the bottom. I have tried to use transform to do this with no luck. Any ideas? Sorry but I can't attach the full code as it is too long, so I will just post a small part so that I can add my codepen link. Please go to my codepen demo. https://codepen.io/Reece_Dev/pen/OgZGvJ
