HTML and CSS Certification Practice Test

The property that changes the text color in CSS is the color property. This property allows you to define the specific color of the text within an HTML element. By using this property, you can enhance the readability and aesthetics of your webpage.

For example, applying the following CSS rule sets the text color of all paragraph elements to blue:

```css

p {

color: blue;

}

```

When you specify a color using the color property, you can use a variety of formats including color names, hex codes, RGB, RGBA, HSL, or HSLA values. This flexibility allows for a wide range of creative possibilities in web design.

The other options, while they may seem related to styling, do not affect the text color directly. The background-color property, for example, changes the background behind the text but has no effect on the text color itself. The text-color and font-color properties do not exist in CSS; they are not valid properties, which is why they are not applicable for this question. Understanding the correct properties is crucial for effectively styling web pages with CSS.
