How do you use javascript in css document?

Answer 1

You cannot use javascript in a css (cascading style sheets) file. You can only write javascript in javascript files (js extension) or in html files inside of <script type="text/javascript"></script> tags.

Answer 2

JavaScript is primarily used for adding interactivity and dynamic behavior to web pages and is not typically embedded directly in CSS documents. However, you can use JavaScript to manipulate CSS properties and styles dynamically. Here's how JavaScript interacts with CSS:

Changing CSS Properties Dynamically:

JavaScript can be used to change the CSS properties of HTML elements dynamically. For example, you can change an element's color, size, position, or visibility based on user interactions or other events. This is often done using the style property of HTML elements.

CSS Classes and Styles:

JavaScript can add or remove CSS classes from HTML elements, which can trigger predefined styles. This is a common approach for creating dynamic effects or animations.

Inline Styles:

JavaScript can set inline styles directly on HTML elements. While not typically recommended for larger-scale applications, this approach is useful for quick, small changes.

CSS Transitions and Animations:

JavaScript can be used to trigger CSS transitions and animations based on events. This allows you to create smooth animations and interactive effects.

HTML:

Responsive Design:

JavaScript can be used to change CSS styles dynamically based on various factors, like screen size or user preferences, enabling responsive web design.

In summary, JavaScript and CSS are closely related and work together to create dynamic and interactive web experiences. While JavaScript is not directly embedded within CSS files, it is used to manipulate and control CSS properties and styles on HTML elements dynamically. and if you are looking for the JavaScript Online Training then, my suggestion is to contact Croma Campus.
