What Even Are Web Components?

Web Components are a built-in browser technology that lets you create reusable UI elements—just like React or Vue components, but without needing a framework.

They’re made up of two core parts:

**🛠️ Custom Elements

You can define your own HTML elements, like <fancy-button> or <user-profile>, complete with their own behavior and styling.

**🕶️ Shadow DOM

The Shadow DOM gives your components built-in style encapsulation, meaning no more accidental CSS leaks from your global styles.

Why Web Components are great (And Why You Should Use Them)

🚀 No Framework? No Problem.

Web Components work out of the box in modern browsers. No need for React, Vue, or Angular—just write HTML like it was meant to be written.

🏗 Reusable, But Not Tied Down.

Since Web Components are framework-agnostic, you can use them in any project, from a raw HTML file to a full-blown React or Vue app.

🔒 Encapsulation = No More CSS Nightmares.

Because Web Components use Shadow DOM, your styles won’t get messed up by other stylesheets floating around your app. Your beautifully crafted buttons will stay beautifully crafted.

💨 Less JavaScript = Faster Sites.

Web Components are native to the browser, meaning they don’t need a heavy runtime or virtual DOM to function. Just write the component, drop it in your HTML, and boom—instant UI.

🎭 Plays Nice with Everything.

Want to use Web Components in a React project? Go for it. Need to add them to a legacy app? No problem. They work everywhere, like a good old-fashioned <div>, but with superpowers.
