jqueryHow can I use jQuery without a class?

You can use jQuery without a class by using the jQuery selector to target elements in the DOM. The jQuery selector works like a CSS selector, allowing you to target elements by their tag name, class name, or id.

For example, you can use the jQuery selector to target all <p> tags on a page like this:

$('p').css('color', 'red');

This code will change the color of all <p> tags on the page to red.

You can also use the jQuery selector to target elements by class or id. For example, if you have a class called .my-class and an id called #my-id, you could target those elements like this:

$('.my-class').css('background-color', 'green');
$('#my-id').css('background-color', 'blue');

This code will change the background color of all elements with the class .my-class to green and all elements with the id #my-id to blue.

You can also use the jQuery selector to target elements based on their attributes. For example, if you have an element with a data-attribute of data-id, you could target it like this:

$('[data-id]').css('font-size', '20px');

This code will change the font size of all elements with the data-id attribute to 20px.
