You can change multiple style attributes with a single line of JavaScript code using the style property. For example:

document.getElementById("myElement").style.color = "red";
document.getElementById("myElement").style.fontSize = "20px";

In the example above, two style attributes (color and font-size) are changed with two lines of code. However, you can also change both attributes with a single line of code like this:

document.getElementById("myElement").style.cssText = "color: red; font-size: 20px;";
