Direct Inline Styling

The simplest way to change text color is by directly manipulating the style attribute of an HTML element. This approach is best suited for quick changes and small projects.

document.getElementById("myHeading").style.color = "blue";

This code snippet targets an element with the ID “myHeading” and sets its color to blue. It’s straightforward and easy to implement, making it a great starting point for beginners.

Using CSS Classes

For more complex projects and maintainable code, using CSS classes is recommended. Define your styles in a separate CSS file and then use JavaScript to toggle these classes on or off.

document.getElementById("myParagraph").classList.add("highlight");

This code adds the “highlight” class to the element with the ID “myParagraph”. The “highlight” class, defined in your CSS file, would contain the desired color change. This approach promotes better code organization and reusability. For information on styling descendant elements, check out how to change descendant color.

Dynamic Color Changes with Variables

JavaScript allows you to store color values in variables, making it easy to dynamically update text color based on user interactions or other events.

let myColor = "green";
document.getElementById("mySpan").style.color = myColor;

This code sets the color of the element with the ID “mySpan” to the value stored in the myColor variable. This dynamic approach opens up possibilities for interactive color changes and more complex styling logic. You might also be interested in learning how to change the color of font.
