Global Variables in HTML Mocktest

In HTML, a global variable refers to a variable declared outside of any function or block, making it accessible throughout the entire HTML document.

The <script> element is commonly used in HTML to define global variables, particularly when using JavaScript to add interactivity and functionality to web pages.

Global variables in HTML are used to store data that needs to be shared and accessed across different parts of an HTML document, improving data management and accessibility.

The global attribute is used inside a <script> element in HTML to declare a global variable, allowing the variable to be accessed and modified across different parts of the HTML document.

In HTML, you can access a global variable defined in one <script> element from another <script> element by using the window object to access the global variable declared in the first script element.

The output will be 'Hello' because globalVar is declared as a global variable inside the <script> element and is accessible within the script, printing 'Hello' when using console.log.

Global variables declared in HTML using the <script> element have global scope, meaning they are accessible throughout the entire HTML document, including within other script elements and HTML elements.

The defer attribute in a <script> element in HTML is used to delay the loading and execution of the script until after the HTML content is parsed, ensuring that global variables are defined before the script runs.

Global variables in HTML can be accessed directly within CSS using custom CSS properties, allowing for dynamic styling and easier management of styles across different parts of the HTML document.

Global variables in CSS are used to store values that can be reused throughout a CSS stylesheet, promoting consistency and simplifying the management of styles.
