Hey there Guys , how are you doing hope you are doing well , yea thanks for asking i am alos doing fine thanks 😃 , i will like to share a tutorial of mine with you today it is a slideshow using HTML , CSS , AND JS....

this slideshow will be able to loop over other images within it container but first...
A Carousle is somewhat of a roller of a particular item keeping them in loop repeating the over and over again till................................................................ well.... till ...... till...

so you gert the picture .
nopw lets start with the code to sreate a slideshow
here is my HTML CODE :

<div class="slideshow-container">

<div class="mySlides fade">
  <img src="https://wallpaperaccess.com/full/4334829.jpg" style="width:100%">
</div>

<div class="mySlides fade">
  <img src="https://wallpaperaccess.com/full/4970607.jpg" style="width:100%">
</div>

<div class="mySlides fade">
  <img src="https://wallpaperaccess.com/full/4970613.jpg" style="width:100%">
</div>

<a class="prev" onclick="slideBtn(-1)">❮</a>
<a class="next" onclick="slideBtn(1)">❯</a>


<h2> Hive Landing Page Automatic Javascript SlideShow </h2>
</div>
<br>

Now as you can see the slideshwo-container is the one that holds all of the contents of itself..

while the images a placed within a div element to place the as an inline-element to a block element which is the DIV tag .

the output without CSS

Here is my CSS :

* {box-sizing: border-box ;}
body {font-family: Verdana, sans-serif; margin:0 ; color : #fff ;
background : linear-gradient(-180deg , #322f2f , black) ;}
.mySlides {display: none}
img {vertical-align: middle;}

/* Slideshow container */
.slideshow-container {
  max-width: 1000px;
  max-height : 400px;
  position: relative;
  margin: auto;
}

/* Next & previous buttons */
.prev, .next {
  cursor: pointer;
  position: absolute;
  top: 50%;
  width: auto;
  padding: 16px;
  margin-top: -22px;
  color: white;
  font-weight: bold;
  font-size: 18px;
  transition: 0.6s ease;
  border-radius: 0 3px 3px 0;
  user-select: none;
}

/* Position the "next button" to the right */
.next {
  right: 0;
  border-radius: 3px 0 0 3px;
}

/* On hover, add a black background color with a little bit see-through */
.prev:hover, .next:hover {
  background-color: rgba(0,0,0,0.8);
}

/* Caption text */
.text {
  color: #f2f2f2;
  font-size: 15px;
  padding: 8px 12px;
  position: absolute;
  bottom: 8px;
  width: 100%;
  text-align: center;
}

/* Number text (1/3 etc) */
.numbertext {
  color: #f2f2f2;
  font-size: 12px;
  padding: 8px 12px;
  position: absolute;
  top: 0;
}

/* The dots/bullets/indicators */
.dot {
  cursor: pointer;
  height: 15px;
  width: 15px;
  margin: 0 2px;
  background-color: #bbb;
  border-radius: 50%;
  display: inline-block;
  transition: background-color 0.6s ease;
}

.active, .dot:hover {
  background-color: #717171;
}
h2{
    text-align :center ;
    margin-top : 30px;
    display : block ;
}
/* Fading animation */
.fade {
  animation-name: fade;
  animation-duration: 1.5s;
}

@keyframes fade {
  from {opacity: .4} 
  to {opacity: 1}
}

/* On smaller screens, decrease text size */
@media only screen and (max-width: 300px) {
  .prev, .next,.text {font-size: 11px}
}

Well You Guessed it we create a css animation using the keyframes to make the fadin effect on the image as they disappear...

output with CSS :

Now Here is MY JAVASCRIPT :

<script>
    //declearing a global variable 
let slideIndex = 1;
//calling the Fumction
showSlides(slideIndex);

//declearing the prev and next btns
function slideBtn(n) {
  showSlides(slideIndex += n);
}
// declearing the slides function
function showSlides(n) {
  let i;
  //declearing the slides variable 
  let slides = document.getElementsByClassName("mySlides");

  //other words a cinditional statement which is that if since n==1 thus if 1 >1 the let n = 1
  //this is placed so thate enev though the images are just siz then the will still be able to repeat themselves 
  //thereby causing a carousel of a looping effect ...   :) 
  if (n > slides.length) {slideIndex = 1}    // for the backward
  if (n < 1) {slideIndex = slides.length}   //for the forward
  for (i = 0; i < slides.length; i++) {
    slides[i].style.display = "none";  
  }
  slideIndex++;
  if (slideIndex > slides.length) {slideIndex = 1}
  slides[slideIndex-1].style.display = "block";  
  //using the setTimeout method in javascript we can set it to continue ton repeat 
  setTimeout(showSlides, 5000); // Change image every 2 seconds
}
</script>

I enclosed the javascript into the script tag which makes it to work in a SFC (single-file-cpmponent VueJs terminology(front-end-framework)).
