Semantic HTML vs Web Components: Building Blocks of a Better Web

Front-end development is all about crafting user experiences, and the foundation of that experience lies in the code itself. Two powerful tools in our arsenal are semantic HTML and web components. But how do they differ, and when should you use each?

Semantic HTML: The Cornerstone of Structure

Imagine a house built entirely of bricks, with no distinction between walls, doors, and windows. That's essentially what non-semantic HTML is like. Semantic HTML, on the other hand, uses descriptive tags like <header>, <nav> and <article> to define the meaning and purpose of content.

Here's why semantic HTML rocks:

Accessibility: Screen readers and assistive technologies can interpret the structure of a page, making it easier for everyone to navigate and understand your content.

Maintainability: Code with clear meaning is easier for you and other developers to understand and modify later.

SEO: Search engines can glean more context from semantic markup, potentially improving your search ranking.

Web Components: Reusable UI Lego Blocks

Web components are like Lego bricks for your web applications. They encapsulate UI elements with their own HTML structure, styles, and behavior. This allows you to:

Create custom UI elements: Build custom components with highly interactive elements, that can be easily integrated across your application.

Encapsulation: Isolate styles and behavior within the component, preventing conflicts with other parts of your code.

Choosing the Right Tool

So, when do you use which? Here's a quick guide:

Use semantic HTML whenever possible: For any page structure, if you can use a default html tag, semantic HTML is the clear winner.

Consider complexity: For highly interactive elements, web components offer more control over behavior compared to plain HTML.

The Future is Bright (and Semantic!)

Web components are a powerful tool, but they shouldn't replace semantic HTML entirely. Think of semantic HTML as the foundation and web components as the custom building blocks that create a beautiful and functional user experience. By using them together, you can craft websites that are not only user-friendly and accessible but also a joy to develop and maintain.

I believe there is another alternative; make accessible web components using semantic HTML. In my opinion it shouldn’t be an either or but instead a combination.
