Can jQuery Directly Modify CSS Class Rules?

Modifying CSS Class Rules with jQuery

Your question centers around modifying CSS class rules on the fly, a task seemingly suited for jQuery's versatility. However, it's important to note that jQuery's core functionality doesn't explicitly provide a means to manipulate CSS class rules directly.

Changing Font Size Only within a Class

Despite the limitations, you can achieve your first goal using JavaScript's native styleSheets property. Here's a proof of concept:

<code class="javascript">// Iterate over style sheets
for (let i = 0; i <p><strong>Saving Modified Styles</strong></p>
<p>For your second question, while jQuery doesn't provide a straightforward method for saving CSS modifications, you can explore the following approach:</p>
<ul>
<li>Parse the CSS stylesheet and extract the modified rules using JavaScript.</li>
<li>Create a string representation of the modified CSS declarations.</li>
<li>Send the string to the server using AJAX for storage or further processing.</li>
</ul>
<p>This approach requires additional server-side implementation, but it provides a possible solution to your requirement. Refer to the provided references for further insights:</p>
