Carousel to display full width of screen for small screens only - html

Question

I have a carousel that is centered and only takes half the screen by adding this to the class "w-50". When the browser resizes to a smaller screen, like a mobile device, I want that carousel to take up the whole width of the screen. To do this I'm sure I'll need to find a way to change that to "w-100", but I'm not sure how to go about doing that.
I have tried to play around with #media in CSS, but haven't had any luck.
<div id="catalogueSelection">
<div id="catalogueCarousel" class="carousel slide w-50" data-ride="carousel" data-interval="5000">
<ol class="carousel-indicators">
<li data-target="#catalogueCarousel" data-slide-to="0" class="active"></li>
<li data-target="#catalogueCarousel" data-slide-to="1"></li>
<li data-target="#catalogueCarousel" data-slide-to="2"></li>
<li data-target="#catalogueCarousel" data-slide-to="3"></li>
<li data-target="#catalogueCarousel" data-slide-to="4"></li>
<li data-target="#catalogueCarousel" data-slide-to="5"></li>
<li data-target="#catalogueCarousel" data-slide-to="6"></li>
</ol>
<div class="carousel-inner">
<div class="carousel-item active">
<img id="franceImage" class="d-block w-100" src="../images/france.jpg">
<div class="carousel-caption countryCaption">
<h2>France</h2>

<div class="carousel-item">

<div class="carousel-item">

<a class="carousel-control-prev" href="#catalogueCarousel" role="button" data-slide="prev">
<span class="carousel-control-prev-icon" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="carousel-control-next" href="#catalogueCarousel" role="button" data-slide="next">
<span class="carousel-control-next-icon" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
</div>
#catalogueCarousel {
margin: auto;
border: 3px solid;
border-color: black;
}
.carousel-inner {
}
.carousel-item img {
height: 500px; !important
overflow: hidden;
opacity: 0.9;
opacity: 0.8;
}
.countryCaption h2 {
color: red;
font-family: 'Prosto One', cursive;
opacity: 1; !important
}
.countryCaption p{
color: darkred;
font-weight: bold;
font-family: 'Prosto One', cursive;
font-size: 20px;
opacity: 1; !important
}
Above is a snippet of the carousel html code, as well as it's stylesheet.
Any tips or ideas to help me resolve this is appreciated.
Thank you.

Answer 1

You can try using a combination of media queries and the !important rule.
Assuming 768px is your mobile breakpoint:
#media(max-width:768px){
#catalogueCarousel {
width: 100% !important;
}
}
Alternatavely you could use jQuery:
function resizeCarousel() {
if($window.width() < 768) {
$('#catalogueCarousel')
.removeClass('w-50')
.addClass('w-100');
} else {
$('#catalogueCarousel')
.removeClass('w-100')
.addClass('w-50');
}
}
resizeCarousel();
$window.resize(resizeCarousel);

Answer 2

You just need add media query for small device. Add below CSS in style sheet i hope it'll resolve your issue. Thanks
#media only screen and (max-width: 768px) {
#catalogueCarousel {
width: 100% !important;
}
}
