How to Assign Colors to Variables in CSS and Save Time on Updates

As a web developer, you've likely worked on CSS files that extend several pages long. While this allows for a high level of customization, it can become tedious to change colors when the client requests a new color scheme. To simplify this task, CSS provides a solution known as CSS Variables.

CSS Variables allow you to define colors as variables that can be easily modified, affecting all elements that use them. This streamlines the process of updating colors throughout your CSS file.

Creating CSS Variables

To create a CSS variable, simply use the following syntax:

:root {
    --main-color:#06c;
}

Here, we've defined a variable named --main-color and assigned it the value #06c.

Applying CSS Variables

Once defined, you can use the var() function to assign the variable to elements:

#foo {
    color: var(--main-color);
}

In this example, the color property of the element with the ID #foo will inherit the value of the --main-color variable.

Manipulating Variables with JavaScript

In addition to using CSS, you can also manipulate CSS variables using JavaScript:

document.body.style.setProperty('--main-color',"#6c0")

This will change the value of --main-color to #6c0, updating all elements that use it.

Browser Support

CSS Variables are supported in all modern browsers, including Firefox, Chrome, Safari, Microsoft Edge, and Opera.

Benefits of Using CSS Variables

Utilizing CSS Variables offers several benefits:

• Centralized Color Management: All colors are defined in one place, making it easy to change them.
• Time-Saving: Modifying one variable updates multiple elements, saving time and effort.
• Consistency: Ensures that colors are consistent throughout your CSS file.
