HTML is the standard language for creating and structuring web pages. It provides the basic building blocks of the internet by defining the content of a webpage — text, images, links, tables, forms, and multimedia elements.
Think of HTML as the skeleton of a website: it organizes information and gives it structure. Each piece of content is wrapped in tags (such as for paragraphs, for headings, for images, and for links) which tell the browser how to display that content.
With HTML, developers can:
Create webpage layouts and organize text, images, and media.
Link pages together for easy navigation.
Build forms to collect user data.
Embed videos, audio, and interactive elements.
Although HTML alone creates static content, when combined with CSS and JavaScript, it becomes the foundation for modern, dynamic websites.
CSS is the language that controls the design and presentation of a website. While HTML structures the content, CSS is used to style it — defining colors, fonts, layouts, spacing, backgrounds, and animations.
Think of CSS as the clothing and design that brings a website to life, making it attractive and user-friendly. CSS allows developers to:
Change text styles (fonts, sizes, colors).
Control layouts (grid systems, flexbox, responsive design).
Add backgrounds, borders, and effects.
Make websites responsive across devices (desktop, tablet, mobile).
Create animations and transitions for interactive experiences.
CSS can be applied inline, internally within an HTML file, or externally through style sheets. External CSS files make it easy to apply consistent styles across multiple webpages.
