What is CSS? 📝

CSS, or Cascading Style Sheets, is a powerful styling language used to design and layout web pages. It separates the visual design from the content, making websites more maintainable, flexible, and attractive.

Understanding CSS Properties 💡

CSS properties are the building blocks of styling elements on a web page. Each property controls a specific aspect of the element's appearance, such as color, size, position, and more.

Examples of CSS Properties:

color: Changes the color of text within an element.
font-size: Sets the font size of an element.
margin: Adds space around an element.
padding: Adds space within an element.
width and height: Defines the size of an element.

CSS Properties and Values 💡

Each CSS property consists of a name and a value that defines how the property should be applied to an element. The value can be a keyword, a number, a string, or even another CSS rule.

CSS Selectors 💡

CSS selectors are used to target specific HTML elements for styling. They can target elements by their ID, class, type, or other attributes.

Examples of CSS Selectors:

#example: Targets an element with the ID example.
.example: Targets elements with the class example.
h1: Targets all <h1> elements.

CSS Box Model 💡

The CSS Box Model defines the structure of every HTML element as a rectangular box with padding, border, and margin. Understanding the Box Model is essential for layout and positioning.

CSS Box Model Properties 💡

width and height: Defines the content area of an element.
padding: Adds space inside the content area.
border: Defines the border of an element.
margin: Adds space around an element.
