Each element serves a specific purpose, contributing to the overall layout and functionality of a webpage.

To create well-structured HTML documents, developers must adhere to semantic HTML principles. This means using tags that accurately describe the content they enclose, such as <header>, <footer>, <article>, and <section>. Semantic HTML improves accessibility and SEO, making it easier for screen readers and search engines to understand the content.

Additionally, mastering HTML involves understanding how to nest elements properly, use attributes effectively, and link external resources like stylesheets and scripts. A solid grasp of HTML sets the foundation for more advanced frontend skills, enabling the creation of robust and accessible web pages.

Cascading Style Sheets (CSS)

Cascading Style Sheets (CSS) are pivotal in frontend development, as they control the presentation and layout of web pages. CSS allows developers to apply styles to HTML elements, including colours, fonts, spacing, and positioning. By separating content from design, CSS makes it easier to maintain and update websites.

Understanding the box model is fundamental to mastering CSS. The box model describes the space an element occupies, including its content, padding, border, and margin. Knowing how to manipulate these properties helps developers create well-structured and visually appealing layouts.

CSS also supports responsive design, ensuring that web pages look good on various devices. Techniques like media queries allow styles to adapt based on the screen size, orientation, or resolution. Additionally, CSS frameworks such as Bootstrap and Tailwind offer pre-defined styles and components, speeding up the development process.
