# 1. Introduction to HTML and CSS

Before we dive into CSS, it’s important to have a basic understanding of HTML (HyperText Markup Language). HTML is the standard markup language for creating web pages and web applications. It provides the structure and content of a web page, while CSS is responsible for the presentation and styling. Both HTML and CSS work together to create visually appealing and functional web pages. # 2. Setting Up Your CSS Environment

To start using CSS, you need to have an HTML file. Inside this HTML file, you will link your CSS file using the `` tag. Here’s an example of how to do this:

“`html










“`

In this example, we have a `` tag inside the `` section of our HTML file. The `href` attribute points to the location of our CSS file, which is named `styles.css` in this case.

# 3. Basic CSS Syntax

CSS uses a specific syntax to target HTML elements and apply styles to them. Here’s an example of basic CSS syntax:

“`css
selector {
property: value;
}
“`

In this example, the `selector` is the HTML element you want to style, the `property` is the aspect of the element’s style you want to change, and the `value` is the specific style you want to apply. For example, if you want to change the color of all `

` elements to blue, your CSS code would look like this:

“`css
h1 {
color: blue;
}
“`

# 4. Selectors and How to Use Them

Selectors are used to target specific HTML elements and apply styles to them. Here are some common selectors:

– Element selector: Targets HTML elements based on their tag name.
– Example: `h1` targets all `

` elements.
– Class selector: Targets HTML elements with a specific class attribute.
– Example: `.my-class` targets all elements with a class of `my-class`.
– ID selector: Targets the HTML element with a specific ID attribute.
– Example: `#my-id` targets the element with an ID of `my-id`.

# 5. CSS Properties and Values

CSS properties are used to specify the aspect of an element’s style you want to change, while values define the specific style you want to apply. Here are some common CSS properties and their values:

– `color`: Sets the text color.
– Example: `color: blue;` sets the text color to blue.
– `background-color`: Sets the background color.
– Example: `background-color: yellow;` sets the background color to yellow.
– `font-size`: Sets the font size.
– Example: `font-size: 20px;` sets the font size to 20 pixels.

# 6. Common CSS Data Types

CSS has several data types that are used to define the values for properties. Here are some common data types:

– ``: Represents a color.
– ``: Represents a length value (e.g., `10px`, `2em`).
– ``: Represents a percentage value.
– ``: Represents an integer value.
– ``: Represents a numeric value.
– ``: Represents a string of text.

# 7. CSS Comments

CSS comments are used to add notes or explanations to your CSS code. They are ignored by the browser when rendering the web page. Here’s an example of how to add a CSS comment:

“`css
/* This is a CSS comment. */
“`

# 8. CSS Best Practices

Here are some best practices to keep in mind when writing CSS code:

– Use meaningful class and ID names.
– Keep your CSS selectors as specific as possible.
– Use comments to explain complex code.
– Organize your CSS code by grouping related styles together.
– Use shorthand properties when possible.
