Mastering CSS Property Manipulation with JavaScript

Chapter 1: Introduction to CSS Property Manipulation
In web development, there are times when we need to modify the CSS properties of HTML elements using JavaScript. This article will explore various techniques to achieve this.
Section 1.1: Using the Style Property
One effective method to change a CSS property of an HTML element is by utilizing the style property. For example:
const element = document.createElement('div');
element.textContent = 'hello world';
element.style.backgroundColor = "lightgreen";
document.body.append(element);
In this snippet, we start by creating a new div element. We then set its textContent to display "hello world" and modify its backgroundColor style to light green. Finally, we append this div to the body of the document.
It's important to note that CSS properties with multiple words are expressed in camelCase when manipulated through JavaScript.
Section 1.2: Using the cssText Property
Another approach to styling an HTML element is by assigning a string of CSS styles to the cssText property of the style. The following example demonstrates this method:
const element = document.createElement('div');
element.textContent = 'hello world';
element.style.cssText = 'background-color: lightgreen';
document.body.append(element);
In this case, we set element.style.cssText to a string that contains standard CSS code. This method yields the same outcome as the previous example.
