Question

How can one exclude a class using the <noscript> tag?

At the moment, I have implemented wow.js to create a fading effect on content as users scroll down. This involves adding the wow class to elements that should fade in, triggering the animation with wow.js. You can find detailed documentation at this link:

However, if a user disables javascript on their browser, it results in failure to apply any CSS styling to elements with the wow class. This is because my stylesheet does not define .wow. I am exploring possible solutions for this issue - one option could be to include the .wow definition in my own stylesheet like .wow {display: block}. Alternatively, is there a way to instruct browsers without javascript to simply ignore the wow class?

Regrettably, including a <noscript> message indicating disabled javascript is not feasible as many individuals accessing the site from work have javascript disabled and need to view it properly.

One unconventional approach to achieve this is by starting from the reverse direction. It's uncertain if the library imposes any restrictions, but you have the option to assign a class to the <html> or <body> tags to indicate that JavaScript functionality is active. To implement this in an inverted manner, consider utilizing a class such as .no-js, which can be removed from the <body> upon successful JS execution.

Here is an implementation example:

<body class="no-js">
    <script type="text/javascript">document.body.classList.remove("no-js");</script>

Subsequently, within your CSS stylesheet, apply the following rule:

.no-js .wow {
    display: block;
}

What do you think about only applying the wow class if the browser supports Javascript?

Here is an example:

<div id="one" class="wowable"></div>
<div id="two" class="wowable"></div>

<script type="text/javascript">
    var wowables = document.getElementsByClassName('wowable');
    for(var i = 0; i < wowables.length; i++) {
        wowables[i].classList.remove( 'wowable' );
        wowables[i].classList.add( 'wow' );
    }
</script>
