Browser Code Editor: Write Code Anywhere
The Toolzie Code Editor gives you a fully-featured coding environment in your browser with syntax highlighting, auto-indentation, and live preview.
What It Does
This browser-based code editor supports HTML, CSS, JavaScript, and other languages with syntax highlighting and auto-indentation. It includes a live preview pane so you can see your HTML and CSS render in real time. Your work is saved to local storage so you do not lose progress if you close the tab.
How to Use It
Select your language from the dropdown menu and start typing code in the editor pane. For web projects, write HTML, CSS, and JavaScript and see the results in the live preview panel on the right. Use the download button to save your code as a file.
Tips & Tricks
Use the live preview to iterate on HTML/CSS layouts quickly without switching between files and a browser. Enable word wrap for long lines of code to avoid horizontal scrolling. Use keyboard shortcuts like Ctrl+Z for undo and Ctrl+S to save.
Use Cases
Students practice coding exercises without installing an IDE. Freelancers quickly prototype HTML email templates on client machines. Developers share code snippets with colleagues by copying from the editor.
