(ii) CSS can be added to HTML elements in 3 ways, Explain?

CSS can be added to HTML elements in 3 ways: Inline - by using the style attribute in HTML elements Internal - by using a <style> element in the section External - by using an external CSS file The most common way to add CSS, is to keep the styles in separate CSS files. However, here we will use inline and internal styling, because this is easier to demonstrate, and easier for you to try it yourself.
