How to use CSS?

CSS (Cascading Style Sheets) is a language used to describe the presentation and styling of HTML elements on a web page. It controls the layout, colors, fonts, spacing, and overall look and feel of your website. Using CSS, you can separate content (HTML) from design, making your code cleaner and easier to maintain. To use CSS, you typically follow these steps: 1. **Add CSS to your HTML**: There are three main ways to apply CSS to an HTML page: - **Inline CSS**: Directly inside an HTML element using the `style` attribute. ```html This is a blue paragraph. ``` - **Internal CSS**: Inside a `` tag within the `` section of your HTML file. ```html p { color: blue; font-size: 16px; } ``` - **External CSS**: Linking to an external `.css` file from your HTML. ```html ``` And in `styles.css`: ```css p { color: blue; font-size: 16px; } ``` 2. **Write CSS Rules**: CSS rules consist of selectors and declarations. The selector targets HTML elements, and declarations define the styles. ```css selector { property: value; property2: value2; } ``` For example: ```css h1 { color: darkgreen; text-align: center; } ``` 3. **Use CSS Selectors**: You can select elements by tag name (`p`), class (`.classname`), ID (`#idname`), or more complex selectors to apply styles precisely. 4. **Test and Adjust**: After applying CSS, open your HTML page in a browser to see the styles. Use browser developer tools to inspect elements and tweak CSS in real-time. By mastering CSS, you gain full control over the aesthetics and responsive behavior of your web pages. There are many advanced features like flexbox, grid, animations, and media queries that help create modern, interactive designs. Starting with basic syntax and gradually exploring these concepts will help you become proficient in web styling.
