How to use CSS?

CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a web page written in HTML or XML. It controls the layout, colors, fonts, spacing, and overall visual appearance of your website, making it an essential tool for web design. To start using CSS, you need to link a CSS file to your HTML document or include CSS directly within your HTML. There are three main ways to apply CSS: 1. **Inline CSS**: Adding styles directly to an HTML element using the `style` attribute. For example: ```html This is a styled paragraph. ``` This method is simple but not recommended for large projects because it mixes content with presentation. 2. **Internal CSS**: Including CSS inside a `` tag within the `` section of your HTML file: ```html p { color: blue; font-size: 16px; } ``` This keeps styles centralized in the HTML file but is best suited for single-page documents. 3. **External CSS**: Linking an external `.css` file to your HTML using the `` tag in the ``: ```html ``` Here, `styles.css` contains your CSS rules. This is the most scalable and maintainable approach, especially for larger websites. CSS syntax consists of selectors and declarations. For example: ```css selector { property: value; property2: value2; } ``` The selector targets HTML elements, and declarations define the styles to apply. For instance: ```css h1 { color: red; font-family: Arial, sans-serif; } ``` This changes all `` headings to red with the Arial font. To learn CSS effectively, start with basic selectors and properties like color, font-size, margin, and padding. Then explore layout techniques using Flexbox and Grid, responsive design with media queries, and advanced styling features. There are many great resources available online, such as MDN Web Docs and freeCodeCamp, to practice and deepen your CSS knowledge. Experimenting with small projects will help you understand how CSS shapes the look and feel of web pages.
