Build a semantic, responsive personal portfolio site (HTML/CSS).
Modern HTML is no longer just about structure; it is about meaning, accessibility, and SEO. : Types like email , tel , url
: Statically analyzes code to quickly find syntax errors and enforce code styling rules.
: Accessible Rich Internet Applications (ARIA) roles and attributes (like aria-label or aria-expanded ) bridge the gap where semantic HTML falls short.
While HTML, CSS, and JavaScript are the core languages, modern front-end development is defined by the ecosystem that surrounds them. The industry has shifted toward a Component-Based Architecture, popularized by frameworks like React, Angular, and Vue. In this paradigm, the separation of concerns is redefined. Instead of separating technologies (HTML in one file, JS in another), modern development often separates concerns by : Statically analyzes code to quickly find syntax
While SCSS/SASS is still popular, PostCSS (with plugins like Autoprefixer) has become standard for transforming modern CSS into compatible code, alongside CSS-in-JS solutions for component-based frameworks. 3. Dynamic Interactivity: Modern JavaScript (ES6+)

New attributes like placeholder , required , autofocus , and pattern (for regular expression validation) provide powerful, built-in validation capabilities without JavaScript. For example, you can validate an email input with a specific pattern using the pattern attribute: ) enable dynamic
Modern front-end development isn't about choosing either vanilla code or frameworks. It's about knowing when to use what.
Custom properties ( --main-color: #3498db; ) enable dynamic, run-time changes across design systems, making dark-mode implementation simple.
CSS variables, also known as custom properties, allow you to store values (like colors, font sizes, or spacing units) in a central location and reuse them throughout your stylesheet. This makes it incredibly easy to maintain consistent theming and make global changes by updating the variable value in a single place.
