You can see the live preview of the HTML on the same page, but you can also show the preview in a new separate tab where it would be more stable.

The highlighted code can also be shown in a separate tab where it would be rendered at once (not in the editor), so the browser's native search function can be used (Ctrl+F). This highlighting is done using a reliable third-party library: highlight.js (license).

The formatting function can be useful too. It is done using an efficient third-party library: JS Beautifier (license).

Available functions:

• Preview (Alt+1) button renders the HTML code in a new tab.
• Highlight (Alt+2) button shows the entire highlighted code in a new tab.
• Format (Alt+3) button beautifies the HTML text.
• Expand all (Alt+4) button expands all elements.
• Collapse all (Alt+5) button collapses all elements.
• Sample (Alt+6) button puts a sample HTML text into the editor.
• Clear (Alt+7) button erases the editor text.
