How can CSS be applied to HTML elements?

CSS can be applied to HTML elements in three main ways: inline CSS, internal CSS, and external CSS.

What is inline CSS?

Inline CSS is applied directly within HTML tags using the 'style' attribute, allowing for specific styling of individual elements.

What is internal CSS?

Internal CSS is placed within a <style> tag in the head section of an HTML document, allowing for styling of multiple elements within that document.

What is external CSS?

External CSS involves creating a separate CSS file that can be linked to one or more HTML files, promoting cleaner code and easier maintenance.

What are CSS selectors?

CSS selectors are patterns used to select the elements you want to style. They define which HTML elements the CSS rules apply to.

Can you explain the structure of a CSS rule?

A CSS rule consists of a selector followed by a set of declarations within curly braces. Each declaration includes a property and a value, separated by a colon.

What are properties and values in CSS?

In CSS, properties are the aspects of an element that can be styled (like color or font-size), and values are the settings assigned to those properties (like 'red' or '16px').

What are the advantages of using external CSS over inline CSS?

External CSS promotes better organization, reusability, and separation of content from presentation, making it easier to manage styles across multiple pages.
