This section is about accessing and modifying the styles of elements in the DOM, a crucial aspect for controlling the appearance of web pages dynamically. One Style. This property allows you to access and modify the inline styles of an element. Using the Style property, you can directly change the CSS of an element from JavaScript. For instance, you can change the color of text, adjust margins, modify font sizes, and more. This is particularly useful for dynamically updating the style in response to user interaction. Class List. The Class List property is a convenient way to access and modify the class attribute of an element. It provides methods like add, remove, and toggle for managing the classes of an element. This is particularly useful for adding or removing styling rules defined in CSS classes. For example, you can add a class to change the visual state of an element, like a button in its active state, or toggle a class to show or hide elements. GetComputedStyle. This method is used to retrieve the values of all CSS properties of an element as computed by the browser. This is useful when you need to know the final appearance of an element, including styles applied through CSS style sheets. It's a read-only method, which means it's used only for retrieving the current styles and not for setting or modifying them. These methods collectively offer a comprehensive toolkit for managing element styles via JavaScript. Whether it's applying inline styles, toggling classes, or retrieving computed styles, understanding these methods is key to effectively controlling the presentation of web elements.
