To create a dynamic and adaptable layout, consider utilizing JavaScript or jQuery to incorporate a flexible

Imagine needing to dynamically include CSS rules that correspond to a specific media condition. Take, for instance, the scenario below:

@media only screen and (min-device-width : 500px){
    .someClass: {
        color: blue;
    }
}

An obvious solution would involve using JavaScript to validate the media query and inject the rule if the test is successful. Consider this approach:

if(matchMedia(only screen and (min-device-width : 500px))){
    $('.someClass').css('color', 'blue');
}

Unfortunately, the downside of this method is that the rule isn't responsive. Any changes in screen size won't automatically update the blue color. While you could add a listener for screen size adjustments, it may be unnecessary.

Therefore, my inquiry is this: Is there a way to insert a responsive rule via JavaScript or JQuery?

Do you have an interest in learning about enquire.js? Take a look below for some insights:

enquire.register("screen and (max-width:1000px)", {

    match : function() {},      // Must be included
                                // Activated when the media query switches 
                                // *from being unmatched to matched*

    unmatch : function() {},    // Optional
                                // If provided, activated when the media query switches 
                                // *from being matched to unmatched*.

    setup : function() {},      // Optional
                                // If provided, a one-time setup function 
                                // that is activated when the handler is first registered.                           

    deferSetup : true,          // Optional, default is false
                                // When set to true, delays executing the setup function until
                                // the media query is first matched. Setup only gets triggered once.

    destroy : function() {}     // Optional
                                // If provided, activated when a handler is unregisters (explained later). 
                                // This allows you to manage the lifecycle of responsive widgets. 
                                // Place cleanup procedures here.

}).listen(); // Further details explained later

EDIT: Adding a pure CSS rule via JavaScript [without relying on a listener] may not be achievable.

You have the ability to generate dynamic CSS with the help of the responsive.js library. This tool allows you to create your responsive rules dynamically, which will then be rendered as native CSS on the client side. Responsive.js utilizes a fluent interface programming style and is capable of functioning even in cases where media queries are not supported (by dynamically rendering the current valid rules).

As an illustration, you can specify the width property as follows:

r$.breakpoints(320,767,1280);
r$.set('width','px').values(100,300,1500).linearInt().applyTo('.class');
