What is the best way to create CSS styles when Javascript is disabled?

Question about Styling:
Embedding extra styles with noscript
Define css if javascript is not enabled

I'm looking to define specific CSS styles only when Javascript is disabled. Currently, I'm using the following code:

<noscript>
    <style type="text/css">
    .needjs {display:none !important;}
    .mwnojs { margin-top: 40px !important; }
    </style>
</noscript>

However, I encountered an error while trying to validate the page source: "Element style not allowed as child of element noscript in this context".

What would be the correct approach to achieve this without invalidating my markup?

Answer №1

<noscript> elements represent "body" content, while <style> elements are associated with the "head" section of a page. This mismatch can lead to errors.

To avoid issues, it is recommended to set non-JavaScript styles as default and then use JavaScript to dynamically update styles when needed. For more information on this approach, refer to the following resource:

Answer №2

Looks quite similar to the topic discussed in this article

"Clarifying the validation issue: noscript can only be used within the body element, while style is restricted to the head element. Thus, combining the two is not permissible."

The placement of your <noscript> tag could make a difference.

Answer №3

Consider trying out the following approach:

<html class="nojs">
<head>
<script type="text/javascript">
document.getElementsById("html")[0].className="";
</script>
<style>
html#nojs {
   /* make changes */
}
</style>

This code snippet removes a specific class during page load, and will only take effect if javascript is enabled on the browser.

Answer №4

To address this issue, consider adding these classes to your default stylesheet and using JavaScript to remove them upon page initialization. This approach will function effectively when JavaScript is operational, ensuring the desired styles are applied accordingly.

Answer №5

One approach could be to disable a specific CSS file using JavaScript, ensuring it remains inactive unless specifically activated.
