Solved: how to change a css variable with javascript

There is no single answer to this question as the two languages approach variable assignment and manipulation in different ways. Generally speaking, however, one issue with trying to change a CSS variable with JavaScript is that the two languages use different syntaxes for declaring and accessing variables. Additionally, CSS variables are typically defined at the style sheet level rather than at the individual element level, which can make them difficult to access from within JavaScript code.

var element = document.getElementById("element");"--variable", "new-value");

This code line is setting a new value for a CSS variable. The first line gets the element with the ID of “element”. The second line sets the value of the CSS variable “–variable” to “new-value”.

CSS variables

CSS variables are a great way to store data in your CSS files without having to use global variables. You can use them to store information like the current page’s width or height, or the current font size.

To use a CSS variable in your JavaScript code, you first need to include the css property in your document’s style sheet. Then, you can define the variable using the var keyword:

var width = document.getElementById(“myElement”).offsetWidth;

You can also use the css property to access individual values from a variable:

var width = document.getElementById(“myElement”).offsetWidth; var height = document.getElementById(“myElement”).offsetHeight;

Control CSS

In JavaScript, there are a few ways to control CSS. One way is to use the css property. This property allows you to set the style for a specific element in your document.

Another way to control CSS is to use the style property. This property allows you to set the style for all elements in your document.
