Edit HTML, CSS and JavaScript in Your Browser

Use this free online HTML editor to open a file, paste code or start a new page. Preview your changes as you work, clean up unwanted HTML and use the AI tools when you need an explanation or a starting point.

Describe the Code You Need

Ask AI to write an HTML, CSS or JavaScript example for your task. Describe what it should do, then review the result in the editor and adapt it to your page.

Start with an Example Request

Choose a request below and click "Insert" to copy it into the AI request box. Add your own details before submitting it.

HTML Email Message

Draft an HTML email with a greeting, message and signature. Add your own details for a customer reply, confirmation or update.

Create a clean, minimal HTML email layout for a generic message. Include: greeting line (e.g. "Hello [Name],"), short message body with 2–3 paragraphs, a closing sentence and a signature block (name, role, company). Use <p>, <br>, <strong> and <a> only. No CSS or inline styles.

Product Description

Create a product description with a heading, feature list and optional specification table. Adapt the HTML to the format your shop or marketplace accepts.

Generate a clean HTML product description for an online marketplace listing. Include: product title in a heading, short intro paragraph, bullet list of 4–6 key features and optional small specification table (3–5 rows). Use <h2>, <p>, <ul>, <li>, <table>, <tr>, <td> only. No CSS attributes.

About Us Section

Introduce your business with a short overview, a mission statement and a few key values. Use the section on a homepage, profile or landing page.

Generate a clean HTML "About Us" section. Include: section heading ("About Us" or "Who We Are"), short overview paragraph, one mission statement paragraph and an unordered list of 3–5 values or strengths. Use <h2>, <p>, <ul>, <li>. No CSS or inline styles.

Contact Information Block

Put your name, address, phone number and email link in one place. Use the block on a contact page, in a sidebar or in a footer.

Create a simple HTML contact information block. Include: business or person name, address on separate lines, phone number line and email as a clickable mailto link. Use <p>, <strong>, <a> only. No tables, lists or CSS.

Small Business Introduction

Describe a local business or service with a heading, a short introduction and a list of benefits. Finish with a clear way for readers to get in touch.

Generate a short HTML promotional snippet for a small business or service. Include: strong headline, 1–2 short paragraphs, bullet list of 3–5 benefits and final call-to-action line (e.g. "Contact us today..."). Use <h2>, <p>, <ul>, <li>. No CSS, no images.

Try Your Own Idea Code Tutorials ▾

Have another idea? Describe the page, content or code you need. You can also open Code Tutorials and choose an HTML, CSS or JavaScript topic.

Review Code Errors with AI

Use the editor to review errors. Request an AI analysis to get explanations and suggested fixes, then check each suggestion against your code and test the result in the preview.

  • Ask for help when a page or script is not behaving as expected.
  • Read the explanation to understand a possible cause.
  • Apply the changes you need and run the code again.

Preview Your Changes

View your HTML, CSS and JavaScript live in the preview while you edit. Check how text, styles and page elements look together, or use Run to open the result in a separate view.

  • Compare your code with the result on the page.
  • Try different styles and check how they affect the layout.
  • Use Run when you want more room to inspect the result.

Code and Preview in One Workspace

The editing area and preview sit one above the other. Work on your content in the upper panel and inspect the output below. Use the text and HTML controls to choose the view you need.

  • Follow your work from the editor down to the preview.
  • Keep the content and its output on the same page.
  • Switch views when you need to inspect the underlying HTML.

Remove Unwanted HTML

Use Clean HTML to remove markup you no longer need. Choose the cleaning options for your content, especially when working with text copied from a document or another website.

  • Choose which tags or attributes to remove.
  • Reduce unnecessary markup before reusing the content.
  • Check the preview after cleaning, as removing styles or tags can change the layout.

Learn with Code Tutorials

Open Code Tutorials and choose an HTML, CSS or JavaScript topic. The selected topic fills in a request for an AI explanation and a code example you can try in the editor.

Search for a topic you want to understand, such as CSS Flexbox, then tailor the request to your question. Read the explanation, edit the example and see what changes. Examples that use a server or database need those services to run.

Explain Code (AI)

Select a piece of HTML, CSS or JavaScript and click Explain Code (AI). Ask what it does, how the parts fit together or where a problem might come from.

Generate Code with AI

Describe a card, form, JavaScript function or another element you need. Use the generated code as a starting point, then edit and test it in the preview.

Live Preview / Run

Preview the current page in your browser or use Run for a separate view. Check HTML, CSS and browser-side JavaScript as you make changes.

Create & Download HTML

Save your current work as an .html file. Enter a file name and click Download to keep a local copy or continue editing later.

HTML Cleaning Tool

Choose which tags and attributes to remove from your HTML. Review the result before saving, particularly if you remove styles, images, links or tables.

Emmet Expand

Expand an abbreviation such as ul>li*3 into HTML, then fill in the content. It is a quick way to write repeated elements without typing every tag.

Code Tutorials & Examples

Browse HTML, CSS and JavaScript topics or search for a specific one. Request an explanation with an example, then change the code to explore how it works.

Save / Share

Create a link to your saved content so you can reopen it or share it with someone else. Use this when you want to show an example or ask for feedback.

Collaboration

Start a real-time collaboration session and invite someone using the session link. Work on the content together and see each other’s edits as they happen.

Open the converter to turn Word content or formatted text into HTML. Clean up the markup and prepare it for use on your website.
