Assigning Colors to Variables in CSS to Simplify Color Modification
Problem: Managing Complex Color Schemes in CSS
When working with extensive CSS files, managing color schemes can become a challenge. Changes requested by clients can lead to time-consuming alterations throughout the entire document. To streamline this process, it's valuable to explore techniques for assigning colors to variables to ensure easy modifications.
Solution: Utilizing CSS Variables
CSS natively supports the concept of CSS variables, enabling you to define colors as variables and assign them to elements. By editing a single variable, you can update the color of all elements that utilize it.
Example: Implementing CSS Variables
Consider the following CSS code:
:root {
--main-color:#06c;
}
#foo {
color: var(--main-color);
}
In this example, --main-color is the variable assigned to the color value #06c. The element with the id #foo uses var(--main-color) to inherit its color by referencing the variable.
Manipulation in JavaScript
CSS variables can also be manipulated dynamically using JavaScript. To change the color assigned to --main-color in JavaScript, execute the following code:
document.body.style.setProperty('--main-color',"#6c0")
Cross-Browser Support
CSS variables are natively supported in modern browsers, including Firefox, Chrome, Safari, Edge, and Opera. This ensures that color modifications can be consistently applied across different browsers.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
