Access Css Variable From Javascript Duplicate

Have you ever wondered how to access CSS variables from JavaScript? You're in luck! In this article, we'll walk you through the process step by step, so you can easily duplicate CSS variables in your JavaScript code.

CSS variables, also known as custom properties, are a powerful feature that allows you to store reusable values in your stylesheets. This makes it easier to maintain and update your code. However, accessing these variables from JavaScript can be a bit tricky. But fear not, we've got you covered.

To access a CSS variable from JavaScript, you first need to get the computed style of an element that has the variable defined. You can use the `getComputedStyle()` method to achieve this. This method returns an object that contains all the CSS properties applied to the element, including the custom properties.

Here's a simple example to demonstrate how to access a CSS variable named `--primary-color` from JavaScript:

:root {
      --primary-color: #3498db;
    }
  


  <div id="myElement">Hello, World!</div>
  
    const element = document.getElementById('myElement');
    const styles = window.getComputedStyle(element);
    const primaryColor = styles.getPropertyValue('--primary-color');
    console.log(primaryColor);

In this example, we define a CSS variable `--primary-color` in the `:root` element. Then, we access this variable in JavaScript by getting the computed style of the `myElement` div and extracting the value of the `--primary-color` property.

Remember that CSS variables are case-sensitive, so make sure to match the variable name exactly as it is defined in your stylesheet. Additionally, keep in mind that CSS variables are global and cascade through the DOM tree, so you can access them from any element in your document.

Once you have accessed the CSS variable in JavaScript, you can then use it to dynamically update your styles, manipulate DOM elements, or perform any other custom logic based on the variable value.

By following these simple steps, you can easily access CSS variables from JavaScript and duplicate their values for use in your code. So go ahead and experiment with this feature to enhance the interactivity and flexibility of your web projects. Happy coding!
