    jQuery Fading Effects

    jQuery fadeIn() and fadeOut() Methods

    The jQueryfadeIn() and fadeOut() methods let you slowly raise or lower the shading of HTML elements to reveal or unclear them.

    Example

    < !DOCTYPE html>
    < html lang="en">
    < head>
    < meta charset="utf-8">
    < title>Example of jQuery Fade-In and Fade-Out Effects< /title>
    < scriptsrc="https://code.jquery.com/jquery-3.5.1.min.js">< /script>
    < style>
    p{
    padding: 15px;
    background: #DDA0DD;
        }
    < /style>
    < script>
    $(document).ready(function(){
        // Fadeing out displayed paragraphs
        $(".out-btn").click(function(){
            $("p").fadeOut();
        });
    
        // Fading in hidden paragraphs
        $(".in-btn").click(function(){
            $("p").fadeIn();
        });
    });
    < /script>
    < /head>
    < body>
    < button type="button" class="out-btn">Fade Out Paragraphs< /button>
    < button type="button" class="in-btn">Fade In Paragraphs< /button>
    < p>This is a paragraph.< /p>
    < p>This is another paragraph.< /p>
    < /body>
    < /html>		
    

    The duration and speed parameters for the fadeIn() and fadeOut() methods, similar to those for other jQuery effects, are available and allow you to set the length of time or speed of the fading animation. The predetermined strings “slow” and “fast” or a number of milliseconds can be used to specify time duration; increasing scores denote slower animations.

    Example

    < !DOCTYPE html>
    < html lang="en">
    < head>
    < meta charset="utf-8">
    < title>Example of jQuery Fade-In and Fade-Out Effects with Different Speeds< /title>
    < scriptsrc="https://code.jquery.com/jquery-3.5.1.min.js">< /script>
    < style>
    p{
    padding: 15px;
    background: #DDA0DD;
        }
    < /style>
    < script>
    $(document).ready(function(){
        // Fading out displayed paragraphs with different speeds
        $(".out-btn").click(function(){
            $("p.normal").fadeOut();
            $("p.fast").fadeOut("fast");
            $("p.slow").fadeOut("slow");
            $("p.very-fast").fadeOut(50);
            $("p.very-slow").fadeOut(2000);
        });
    
        // Fading in hidden paragraphs with different speeds
        $(".in-btn").click(function(){
            $("p.normal").fadeIn();
            $("p.fast").fadeIn("fast");
            $("p.slow").fadeIn("slow");
            $("p.very-fast").fadeIn(50);
            $("p.very-slow").fadeIn(2000);
        });
    });
    < /script>
    < /head>
    < body>
    < button type="button" class="out-btn">Fade Out Paragraphs< /button>
    < button type="button" class="in-btn">Fade In Paragraphs< /button>
    < p class="very-fast">This paragraph will fade in/out with very fast speed.< /p>
    < p class="normal">This paragraph will fade in/out with default speed.< /p>
    < p class="fast">This paragraph will fade in/out with fast speed.< /p>
    < p class="slow">This paragraph will fade in/out with slow speed.< /p>
    < p class="very-slow">This paragraph will fade in/out with very slow speed.< /p>
    < /body>
    < /html>		
    

    Note:
    The effect of the fadeIn() and fadeOut() methods is comparable to that of the show() and hide() methods, but unlike those methods, the fadeIn() and fadeOut() methods only animate the opacity of the target elements, not their dimensions.

    A callback function that will be run after the fadeIn() or fadeOut() method has finished running is also an option.

    Example

    < !DOCTYPE html>
    < html lang="en">
    < head>
    < meta charset="utf-8">
    < title>Example of jQuery Fade-In and Fade-Out Effects with Callback< /title>
    < scriptsrc="https://code.jquery.com/jquery-3.5.1.min.js">< /script>
    < style>
    p{
    padding: 15px;
    background: #DDA0DD;
        }
    < /style>
    < script>
    $(document).ready(function(){
        // Display alert message after fading out paragraphs
        $(".out-btn").click(function(){
            $("p").fadeOut("slow", function(){
                // Code to be executed
    alert("The fade-out effect is completed.");
            });
        });
    
        // Display alert message after fading in paragraphs
        $(".in-btn").click(function(){
            $("p").fadeIn("slow", function(){
                // Code to be executed
    alert("The fade-in effect is completed.");
            });
        });
    });
    < /script>
    < /head>
    < body>
    < button type="button" class="out-btn">Fade Out Paragraphs< /button>
    < button type="button" class="in-btn">Fade In Paragraphs< /button>
    < p>This is a paragraph.< /p>
    < /body>
    < /html>
    

    jQuery fadeToggle() Method

    The jQueryfadeToggle() method shows or hides the chosen elements by animating there own opacity so that, if they are initially visible, they fade out, and, if they are hidden, they fade in (i.e. toggles the fading effect).

    Example

    < !DOCTYPE html>
    < html lang="en">
    < head>
    < meta charset="utf-8">
    < title>Example of jQuery Fade-Toggle Effect< /title>
    < scriptsrc="https://code.jquery.com/jquery-3.5.1.min.js">< /script>
    < style>
    p{
    padding: 15px;
    background: #DDA0DD;
        }
    < /style>
    < script>
    $(document).ready(function(){
        // Toggles paragraphs display with fading
        $(".toggle-btn").click(function(){
            $("p").fadeToggle();
        });
    });
    < /script>
    < /head>
    < body>
    < button type="button" class="toggle-btn">Fade Toggle Paragraphs< /button>
    < p>This is a paragraph.< /p>
    < p>This is another paragraph.< /p>
    < /body>
    < /html>				
    

    Like the fadeIn() and fadeOut() methods, users can control the period or quickness of the fade toggle animation by setting the period variable for the fadeToggle() method.

    Example

    < !DOCTYPE html>
    < html lang="en">
    < head>
    < meta charset="utf-8">
    < title>Example of jQuery Fade-Toggle Effect with Different Speeds< /title>
    < scriptsrc="https://code.jquery.com/jquery-3.5.1.min.js">< /script>
    < style>
    p{
    padding: 15px;
    background: #DDA0DD;
        }
    < /style>
    < script>
    $(document).ready(function(){
        // Fade Toggles paragraphs with different speeds
        $(".toggle-btn").click(function(){
            $("p.normal").fadeToggle();
            $("p.fast").fadeToggle("fast");
            $("p.slow").fadeToggle("slow");
            $("p.very-fast").fadeToggle(50);
            $("p.very-slow").fadeToggle(2000);
        });
    });
    < /script>
    < /head>
    < body>
    < button type="button" class="toggle-btn">Fade Toggle Paragraphs< /button>
    < p class="very-fast">This paragraph will fade in/out with very fast speed.< /p>
    < p class="normal">This paragraph will fade in/out with default speed.< /p>
    < p class="fast">This paragraph will fade in/out with fast speed.< /p>
    < p class="slow">This paragraph will fade in/out with slow speed.< /p>
    < p class="very-slow">This paragraph will fade in/out with very slow speed.< /p>
    < /body>
    < /html>		
    

    For such fadeToggle() technique, users could also clarify a callback function.

    Example

    < !DOCTYPE html>
    < html lang="en">
    < head>
    < meta charset="utf-8">
    < title>Example of jQuery Fade-Toggle Effect with Callback< /title>
    < scriptsrc="https://code.jquery.com/jquery-3.5.1.min.js">< /script>
    < style>
    p{
    padding: 15px;
    background: #DDA0DD;
        }
    < /style>
    < script>
    $(document).ready(function(){
        // Display alert message after fade toggling paragraphs
        $(".toggle-btn").click(function(){
            $("p").fadeToggle(1000, function(){
                // Code to be executed
    alert("The fade-toggle effect is completed.");
            });
        });
    });
    < /script> 
    < /head>
    < body>
    < button type="button" class="toggle-btn">Fade Toggle Paragraphs< /button>
    < p>This is a paragraph.< /p>
    < /body>
    < /html>
    

    jQuery fadeTo() Method

    The.fadeIn() method and the jQueryfadeTo() method are similar, but the latter allows users to fade in the elements to a specific contrast level.

    $(selector).fadeTo(speed, opacity, callback);

    The goal elements’ finished opacity is specified by the necessary opacity parameter, which can be a value between 0 and 1. For such a method, the length of time or speed parameter, which specifies the length of the fade-to-animation, is also necessary.

    Example

    < !DOCTYPE html>
    < html lang="en">
    < head>
    < meta charset="utf-8">
    < title>Example of jQuery Fade-To Effect< /title>
    < scriptsrc="https://code.jquery.com/jquery-3.5.1.min.js">< /script>
    < style>
    p{
    display: none;
    padding: 15px;
    background: #DDA0DD;
        }
    < /style>
    < script>
    $(document).ready(function(){
        // Fade to paragraphs with different opacity
        $(".to-btn").click(function(){
            $("p.none").fadeTo("fast", 0);
            $("p.partial").fadeTo("slow", 0.5);
            $("p.complete").fadeTo(2000, 1);
        });
    });
    < /script>
    < /head>
    < body>
    < button type="button" class="to-btn">Fade To Hidden Paragraphs< /button>
    < p class="none">This is a paragraph.< /p>
    < p class="partial">This is another paragraph.< /p>
    < p class="complete">This is one more paragraph.< /p>
    < /body>
    < /html>		
    

    FAQS

    Q1. What is the fade option?

    For adding and removing animated elements, use the Fade In/Fade Out behaviour. For instance, you can use the Fade In/Fade Out behaviour to make moving text on the screen gradually appear before disappearing at the end of its duration.

    Q2. How do you make a fade effect in Javascript?

    The onload=fadeIn parameter is used to automatically invoke the fadeIn() function. The function fadeIn() calls an internal method called setInterval(), which requires two parameters: a function reference (in this case, show()) and a time interval (to take reference of function after selected interval).

    Q3. How do you use fade effect?

    Simply drag and drop your video on to any of the timeline, choose a transition from the left sidebar’s transition tab, and then drop it onto the timeline. A video, audio, or image clip can also have a fade-in or fade-out added to it by identifying it in the timeframe and using the fade tab.

    Q4. What is Fade In USED FOR?

    Instead of cutting unexpectedly through one scene to the next, film editors will often use an introductory shot or transformation technique called a “fade in” to introduce viewers to new imagery.
