Optimizing Workflow for Efficient CSS Coding
Variables
CSS variables (custom properties) let you store reusable values, making your styles easier to update and maintain.
Declare variables in the :root selector and prefix them with --:
:root {
--blue-color: #3f42f3;
}
Once we have declared a variable, we can apply it to any CSS property using the var() function. For instance, to assign the color property of an <h1> element the value of our --blue-color variable, we can write:
h1 {
color: var(--blue-color);
}
Let's combine the knowledge of variable declaration and usage in the following example:
index.html
styles.css
In this example, several variables control the card's colors. Updating a single variable updates the styles everywhere it's used.
Overriding Properties
To change specific styles within a component, redefine the same property inside a more specific selector.
Example (traffic light):
index.html
styles.css
The base .signal class holds shared styles, while .stop, .slow-down, and .proceed override individual colors.
CSS variables improve flexibility and maintainability.
Overriding allows fine-tuning styles without repeating shared rules.
