About Course
CSS (Cascading Style Sheets) is a powerful language used in web development to control how HTML elements are presented on screen, paper, or other media. Let’s dive into the details:
- What CSS Does:
- Styling: CSS defines the styling of web pages, including layout, colors, fonts, and animations.
- Separation of Concerns: It separates content (HTML) from appearance (CSS), making code more modular and maintainable.
- Flexibility: CSS allows you to create diverse designs and adapt to different devices.
- How CSS Works:
- CSS is rule-based. You define rules specifying styles for specific elements or groups of elements.
- For example, you can make your main heading appear as large red text using the following simple CSS rule:
h1 {
color: red;
f
font-size: 5em;
}
-
- Here,
h1
refers to the main heading element, and we set its color to red and font size to 5 times the default size.
- Browser Default Styles:
- When you view an HTML page in a browser, you see basic styles applied by default.
- These styles ensure basic readability even if no explicit styling is specified.
- However, CSS lets you take control and create visually appealing designs.
- Use Cases for CSS:
- Text Styling: Change font properties, colors, and alignment.
- Layout: Create multi-column layouts, responsive designs, and grids.
- Effects: Add animations, transitions, and interactive elements.
- External Stylesheets:
- CSS rules can be stored in separate files (external stylesheets).
- These files are linked to HTML documents, allowing consistent styling across multiple pages.
Remember, CSS empowers you to transform plain HTML into beautifully styled web pages. Explore its features, experiment, and enjoy the creative possibilities!
