About
HTML Online Viewer is a fast HTML editor and formatter with an instant live
preview. View, edit and format your HTML in real-time!
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 is more stable.
The viewer highlights the HTML for better readability using the high performance editor: Ace (license). The highlighted code can also be shown in a separate tab where it is 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.
