What is an HTML viewer?
An HTML viewer renders HTML code, so you see headings, text, images, tables and forms instead of raw HTML tags. Use it to preview an HTML email, a page you are building or an HTML response from an API.
How to view an HTML file online?
Press Upload and choose an .html or .htm file: the HTML viewer opens it and renders it at once. To view HTML code, paste it into the editor and press View.
Can I view HTML with CSS and JavaScript?
Yes. Styles in <style> tags and style attributes are applied, and scripts in <script> tags run. Linked CSS files, scripts and images load when their address starts with https://, such as https://example.com/style.css. Files linked by a relative path, such as css/style.css, do not load, because only the HTML itself is opened.
