HTML: Structure and Content
HTML, or HyperText Markup Language, serves as the backbone of every web page. It defines the structure and content of a website by utilizing tags. These tags enclose elements, indicating their purpose and relationship within the document. For instance, the <h1> tag signifies a heading, <p> creates paragraphs, and <img> displays images. HTML5, the latest version of HTML, introduced new semantic elements such as <header>, <nav>, <article>, and <footer>, which enhance the organization and accessibility of web content.
Apart from structural elements, HTML allows for hypertext linking through the <a> tag. By specifying the URL within the href attribute, you can create hyperlinks that connect different web pages. Additionally, HTML supports creating lists (<ul>, <ol>), tables (<table>), forms (<form>), and multimedia elements like audio (<audio>) and video (<video>).
CSS: Styling and Design
Cascading Style Sheets (CSS) play a pivotal role in beautifying web pages and refining their visual presentation. CSS allows you to exert control over HTML elements, manipulating their appearance, layout, and behavior. By separating the style from the structure, CSS enhances the maintainability and reusability of your code.
CSS operates through selectors, which target specific HTML elements to apply styles. Selectors can be simple (e.g., element selectors like “h1” or “p”) or complex (e.g., class selectors like “.header” or ID selectors like “#navbar”). In addition to selectors, CSS provides a vast array of properties and values that determine how elements should look. You can adjust colors, fonts, spacing, borders, backgrounds, and much more using CSS.
To apply CSS to an HTML document, you can embed the styles within a <style> block in the HTML file, include an external CSS file using the <link> tag, or use inline styles directly within the HTML elements. CSS also offers the concept of cascading, where styles can be inherited from parent elements and overridden by more specific rules.
Advanced CSS techniques involve creating responsive designs through media queries, which adapt the layout based on the user’s device or screen size. CSS preprocessors like Sass or Less offer additional features such as variables, nesting, and mixins, making your CSS code more modular and maintainable.
