Question

Instructions for incorporating animation into the CSS properties of an element as the class is updated using jQuery

The issue:

I am facing a challenge with an HTML element that has a class called hidden which hides the element with the css attribute display: none;. When I use JavaScript to remove the class, the element immediately becomes visible again (the original display property is restored). What I would like to achieve is to have a smooth animation when the element becomes visible again, similar to how it can be done with jQuery using $('.hidden').show(1000) or $('.hidden').fadeIn(1500). I attempted to use .animate() in conjunction with removing the class, but it did not produce the desired effect.

The conditions

It is important not to interfere with the inline CSS properties of the element (especially avoiding setting display: block)
The behavior should resemble that of jQueryUI's removeClass method: http://jqueryui.com/removeClass/

The inquiry:

Is there a way to animate the changes (with a duration > 0) when I remove or alter the class of the HTML element?

The code:

CSS:

.hidden{
display: none;
}

HTML

<div class="hidden"> Lorem ipsum </div>

JS

$('.hidden').removeClass('hidden')

javascript jquery css

To enhance your website's interactivity, consider implementing the following JavaScript code along with your HTML and CSS:

$('.hidden').css({ // Adjust the CSS properties directly
    display: 'inline', // Set the desired display property
    opacity: 0 // Make it completely transparent
})
.stop() // Recommended to prevent conflicts from multiple animations
.animate({ // Gradually update the CSS properties
    opacity: 1 // Fade in the element
}, 2000, // Duration of 2 seconds
function(){
    var $this = $(this)
    $this.removeClass('hidden'); // Remove the "hidden" class if needed
    alert($this.css('display')); // Display the current display property value after animation
});

Make sure to remove the specific class that is causing the fade issue.

If you're having trouble, give this example a try.

Here is the HTML:

<h1 class="hide" style="display:none;">Display</h1>

And here is the JavaScript code:

$(function () {
    $(".hide").fadeIn('slow');
});

$('.hidden').fadeIn(1000, function(){$(this).removeClass('hidden').css('display', '');});

By utilizing the fadeIn method, the element will be displayed with a smooth animation before removing the hidden class.

$('.hidden').fadeIn(1000, function(){$(this).removeClass('hidden').css('display', '');});

By utilizing the fadeIn method, the element will be displayed with a smooth animation before removing the hidden class.

To ensure smooth animation on modern browsers, consider using CSS transitions!

.hidden{
    display: none;
}
.hidden.fadeIn{
    display: block;
    opacity:0;
    visibility:hidden;
    -webkit-transition: all 1s;
    -moz-transition: all 1s;
    -ms-transition: all 1s;
    -o-transition: all 1s;
    transition: all 1s;
}
.hidden.fadeIn.do{
    opacity:1;
    visibility:visible;
}

In JavaScript, you can apply the classes like so:

$('.hidden').addClass('fadeIn');
setTimeout(function(){$('.hidden.fadeIn').addClass('do');},10);

If not using setTimeout, both class changes may happen simultaneously without triggering the animation.

EDIT

You could simplify by updating the rule for the hidden class:

.hidden{
    display: none;
    opacity:0;
    visibility:hidden;
    -webkit-transition: all 1s;
    -moz-transition: all 1s;
    -ms-transition: all 1s;
    -o-transition: all 1s;
    transition: all 1s;
}
.hidden.fadeIn{
    display: block;
    opacity:1;
    visibility:visible;
}

Now only one class needs to be added with JS:

function fade(){
    $('.hidden').addClass('fadeIn');
}
setTimeout(fade,10);
