Lesson 10 – Introduction to CSS
Overview:
CSS is the cornerstone of web design, allowing for the presentation and styling of HTML elements. Let's grasp its essence:
Understanding CSS: Cascading Style Sheets:
- CSS defines styles, layouts, and visual presentation for web documents.
Linking CSS with HTML5:
- Methods to link external CSS files with HTML documents using `<link>` or internal CSS via `<style>` tags.
Basic CSS Properties for Styling HTML Elements:
- Properties like `color`, `font-family`, `background`, `margin`, `padding`, and more for element styling.
Practical Application:
Let's practically apply CSS concepts to enhance the visual appeal of web pages:
Linking External CSS Files to HTML Documents:
Link an external CSS file to an HTML document:
```html
<!DOCTYPE html>
<html>
<head>
<title>My Website</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<!-- Content -->
</body>
</html>
```
- `<link>` tag establishes a connection between HTML and external CSS (`styles.css`).
Applying CSS Rules for Text, Backgrounds, and Layouts:
Apply CSS rules to style elements:
```css
/ styles.css /
body {
font-family: Arial, sans-serif;
background-color: f4f4f4;
color: 333;
margin: 0;
padding: 0;
}
```
- `font-family`, `background-color`, `color`, `margin`, and `padding` are CSS properties applied to the `body` element.
Exploring CSS Impact on Visual Appearance of Web Pages:
Observe the transformative impact of CSS on web page appearance:
```html
<style>
h1 {
color: ff6600;
text-align: center;
}
</style>
<body>
<h1>Welcome to My Site</h1>
<!-- Other content -->
</body>
```
- CSS applied to the `h1` element modifies its color and text alignment.
CSS empowers web designers to unleash creativity, transforming mere HTML structures into visually appealing web pages. By understanding its fundamentals, linking stylesheets, and applying CSS rules effectively, you'll elevate the aesthetic appeal and user experience of your web projects. As you delve deeper into CSS, you'll discover its potential to craft visually captivating and user-friendly web interfaces, making your online presence stand out in the digital realm.
