JavaScript vs HTML/CSS
HTML, CSS, and JavaScript are the core building blocks of web development. While they often work together, they serve very different purposes. Let’s break down how they differ and complement each other.
🔤 HTML (Structure)
- Defines page content & structure
- Headings, paragraphs, images, links, forms
- Uses tags like
<div>,<p>,<img> - Static by nature
🎨 CSS (Style)
- Controls design and presentation
- Applies colors, fonts, spacing
- Responsive layouts with media queries
- Uses selectors like
.class,#id
⚙️ JavaScript (Behavior)
- Adds interactivity & logic
- Form validation, animations, dynamic content
- Can manipulate HTML & CSS using DOM
- Used for both frontend & backend
