How to Use This Tool
-
The **CSS Variables Editor Tool** is a dynamic and interactive way to create, edit, and preview CSS variables (`--custom-properties`) in real time. Perfect for front-end developers, designers, and UI creators, this tool helps you experiment with color schemes, fonts, spacing, and more — all while instantly visualizing how the changes affect your website components. It’s a must-have resource for anyone working with CSS design systems or theme customization.
To get started, use the **“Add Variable”** button to create your own CSS variables. You can name each variable (for example, `--primary-color`, `--font-family`, etc.) and assign it a value such as a color code, font, or unit size. Every modification you make updates the **live preview area**, which includes common website components like headers, cards, buttons, and grids. This gives you a realistic sense of how your CSS variables will appear in a real layout.
You can also choose from a variety of **preset themes** like *Light*, *Dark*, *Blue*, *Green*, *Purple*, *Minimal*, or *High Contrast* to apply ready-made palettes instantly. For targeted adjustments, the **Component Focus** feature allows you to preview variable changes on specific parts of the layout, such as only the header, buttons, or footer. Once satisfied, click **“Copy CSS”** or **“Export CSS Variables”** to copy your code, or **“Export Full Page Code”** to download a ready-to-use HTML template.
The **CSS Variables Generator and Editor Tool** operates completely in your browser, ensuring privacy and instant results without installation or sign-in. It’s ideal for building responsive UI themes, customizing Bootstrap-based websites, or creating reusable design systems. With its visual preview and export flexibility, this editor simplifies CSS theming for both beginners and professionals.
