CSS (Cascading Style Sheets) is a stylesheet language used to describe the presentation of a document written in HTML or XML. It controls the layout, colors, fonts, and overall visual appearance of web pages.
CSS rules are made up of selectors and declarations:
- Selectors: Define which HTML elements the style applies to.
- Declarations: Consist of property-value pairs that specify the styling for the selected elements.
WHY SHOULD WE USE CSS?
Using CSS offers numerous benefits for web development, enhancing the appearance, usability, and maintainability of websites. Here are some key reasons to use CSS:
1. Separation of Content and Presentation:
CSS separates the content of a webpage (HTML) from its presentation (styling). This makes the content more accessible and the code easier to maintain.
2. Consistent Styling:
CSS allows you to apply consistent styling across multiple pages of a website. By defining styles in an external stylesheet, you can ensure a uniform look and feel throughout your site.
3. Improved Readability and Maintenance:
With CSS, you can keep your HTML cleaner and more readable by removing inline styles. This also makes it easier to update styles globally from a single stylesheet rather than modifying each HTML file individually.
4. Responsive Design:
CSS enables responsive web design through media queries, allowing webpages to adapt to different screen sizes and devices. This ensures a better user experience across desktops, tablets, and smartphones.
