Online HTML Editor

Introducing Our New Online HTML Editor: Code, Preview, and Learn All in One Place

Hi everyone! 

As the creator of ArtDraw , I’ve always been passionate about building tools that help designers and developers bring their ideas to life. While we started as an online SVG image editor with a blog focused on design, programming, and tech news, our journey has naturally evolved into something even more exciting.

While redesigning ArtDraw, I added a new section called "HTML Tutorials" , where I explain almost 100 HTML5 tags in detail. As part of that work, I needed a way to include source code inside articles — and not just show it, but highlight it for clarity and learning. That led me to build a solid infrastructure for handling code presentation.

And from there… something bigger started taking shape.

I’m excited to announce our brand-new online HTML + CSS + JavaScript editor , built on top of the powerful and well-known ACE Editor . It’s fast, flexible, and completely browser-based — no installation required.

What You Can Do With It

This editor is designed to be simple yet effective. Here’s how you can use it:

• Write and test code instantly : Just click the "Run" button and see your code come to life in real time.
• Choose your layout :

Vertical split view: Code on the left, preview on the right 

Horizontal split view: Code on top, preview below (Perfect for mobile devices!)

• Dark or Light mode : Pick the theme that suits your style best
• Save your code locally : No cloud storage, no accounts — just a simple download so you stay in control.

Start with templates : Use the dropdown menu under “Templates” to begin with pre-made structures like:

• Bootstrap Home Page
• Bootstrap Article
• And more!

A Little Console for Quick Debugging

Yes, this editor isn’t meant to replace your full development environment — think of it more as a playground. Still, I’ve included a basic console to help you catch errors and test small snippets of JavaScript. It's not a substitute for DevTools (F12), but it gets the job done when you're trying things out quickly.

Who Is This For?

This tool is ideal for:

• Students learning web development
• Designers who want to experiment with front-end code
• Developers who need a quick sandbox to test ideas

It’s not a project builder or a full IDE — it’s a single-file editor, perfect for experimentation, learning, and sharing small examples.

Why Build This?

Because sometimes you just want to write a bit of HTML, add some styles and scripts, and see what happens — without setting up a server, installing packages, or configuring environments. This editor lets you focus on what matters: your code .

You can access the editor directly from our site — no login, no setup, no hassle.

If you’re learning, teaching, or just curious about how things work on the web, I hope you find this tool useful. Try it out, let me know what you think, and feel free to share it with others who might enjoy it too.

As always, thanks for being part of the ArtDraw community!

Happy coding!
