How can I add fade in, fade out effects

Question

I have a simple script which works as a simple html gallery. However, I need to add some transition effects to my gallery, something like fade in, fade out, or the effect of something similar to the subtitles at the end of every movie (you know what I mean).

How can I solve this? I would like to make it using only JS, HTML, CSS, without external plugins. Is it possible? For now on, I have only something like this below:

<head>
<title>Test</title>
    <script>
var images = [      "https://upload.wikimedia.org/wikipedia/commons/7/70/Example.png",
            "https://upload.wikimedia.org/wikipedia/commons/a/a9/Example.jpg",

                "https://upload.wikimedia.org/wikipedia/commons/d/d6/Beispiel.png"
         ];

var links = [       "http://www.example1.com",
            "http://www.example2.com",
            "http://www.example3.com",
            "http://www.example4.com", 
                "http://www.example5.com", 
            "http://www.example6.com",
         ];
var i = 0;
var renew = setInterval(function(){
        if(i==images.length) i=0;
        document.getElementById("img1").src = images[i]; 
    document.getElementById("link1").href = links[i]; 

        if(i+1==images.length) i=-1;
        document.getElementById("img2").src = images[i+1];
    document.getElementById("link2").href = links[i+1];

        if(i+2==images.length) i=-2;
        document.getElementById("img3").src = images[i+2];
    document.getElementById("link3").href = links[i+2];

        i+=3;


},5000);
</script>

</head>

I just created a JQuery function and added it to your script. Now when you click on that button it will do as it says. It is just as an example how to do that

<html>
<head>
<title>Test</title>
    <script>

var images = [      "https://upload.wikimedia.org/wikipedia/commons/7/70/Example.png",
            "https://upload.wikimedia.org/wikipedia/commons/a/a9/Example.jpg",

            "https://upload.wikimedia.org/wikipedia/commons/e/e2/P%C5%99%C3%ADklad.jpg",
                "https://upload.wikimedia.org/wikipedia/commons/d/d6/Beispiel.png"
         ];

var links = [       "http://www.example1.com",
            "http://www.example2.com",
            "http://www.example3.com",
            "http://www.example4.com", 
                "http://www.example5.com", 
            "http://www.example6.com",
         ];
var i = 0;
var renew = setInterval(function(){
        if(i==images.length) i=0;
        document.getElementById("img1").src = images[i]; 
    document.getElementById("link1").href = links[i]; 

        if(i+1==images.length) i=-1;
        document.getElementById("img2").src = images[i+1];
    document.getElementById("link2").href = links[i+1];

        if(i+2==images.length) i=-2;
        document.getElementById("img3").src = images[i+2];
    document.getElementById("link3").href = links[i+2];

        i+=3;


},5000);
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<script type='text/javascript'>

$(document).ready(function(){
    $(".btn1").click(function(){
        $("#link1").fadeOut()
    });
    $(".btn2").click(function(){
        $("#link1").fadeIn();
    });
});
</script>
</head>
<body>

</script>
</head>

<body>

<div align="center">
<button class="btn1">Fade out</button>
<button class="btn2">Fade in</button>
<a href="http://www.example1.com" id="link1"><img src="https://upload.wikimedia.org/wikipedia/commons/7/70/Example.png" id='img1' > </a> </br></br>

@yak it can be done but you have to specify any event when it should be done — shv22, May 09 '16 at 10:56

You can definitely achieve some effects with CSS. But not all (like jQuery-ui's blind)

most effects consist of changing:
- opacity: [0-1]
- display: relative; left: [X]px; top: [Y]px or transform: translate([X]px,[Y]px)
- overflow: hidden
- and an animation:

either CSS:

#img {
  animation: fade-in 2s infinite;
} 

@keyframe fade-in { 
  from {
    left: -200px
  }
  to {
    left: 0 
  }
}`

or JavaScript:

var img = document.getElementById('img');
for(i = 1; i <= 100; i++){
  (function(step) {
    setTimeout(function() {
      img.style.transform = "translate(-"+(200-step*2)+"px, 0)";
    }, step * 20);
  })(i);
}

to achieve something like blind, you must move an image-container <div> left, while moving the image right at the same speed.
- Here's a simplified blind effect example https://jsfiddle.net/warkentien2/Lh10phuv/5/

Here I've implemented 8 pure JavaScript effects (including blind, with instructions)

- fade out http://codepen.io/warkentien2/pen/EyxpVq

You can try this one. I have not changed your code at all.

HTML

<div align="center"> 
 <a href="http://www.example1.com" id="link1">
  <img src="https://upload.wikimedia.org/wikipedia/commons/7/70/Example.png" id='img1' > 
 </a> 
</br>
</br>
<a href="http://www.example2.com" id="link2">
   <img src="https://upload.wikimedia.org/wikipedia/commons/a/a9/Example.jpg" id='img2' > 
</a>
<br>
<br>
  <a href="http://www.example3.com" id="link3">
 <img src="https://upload.wikimedia.org/wikipedia/commons/c/ce/Example_image.png" id='img3'>

 </a>
  <br>
  </div>

Css

  <style>
     .animate{transition:all 1s ease; opacity:0;}
  </style>

Js

  <script>
      var images = [          "https://upload.wikimedia.org/wikipedia/commons/7/70/Example.png",

     var i = 0;
    var renew = setInterval(function(){
      if(i==images.length) i=0;
    document.getElementById("img1").src = images[i]; 
        document.getElementById("link1").href = links[i];
            document.getElementById('link1').style.opacity = 0; 
            setTimeout(function(){
                document.getElementById('link1').setAttribute("class", "animate");
                document.getElementsByClassName('animate')[0].style.opacity = 1;
                setTimeout(function(){document.getElementById('link1').removeAttribute("class", "animate")},500)
            },500)


    if(i+1==images.length) i=-1;
    document.getElementById("img2").src = images[i+1];
        document.getElementById("link2").href = links[i+1];
            document.getElementById('link2').style.opacity = 0; 
            setTimeout(function(){
                document.getElementById('link2').setAttribute("class", "animate");
                document.getElementsByClassName('animate')[1].style.opacity = 1;
                setTimeout(function(){document.getElementById('link2').removeAttribute("class", "animate")},500)
            },500)

    if(i+2==images.length) i=-2;
    document.getElementById("img3").src = images[i+2];
        document.getElementById("link3").href = links[i+2];
            document.getElementById('link3').style.opacity = 0;
            setTimeout(function(){
                document.getElementById('link3').setAttribute("class", "animate");
                document.getElementsByClassName('animate')[2].style.opacity = 1;
                setTimeout(function(){document.getElementById('link3').removeAttribute("class", "animate")},500)
            },500)

    i+=3;



     },5000);
