Live Code Preview

This lesson is part of Web Developer Tools · All levels

Summary

Live code preview provides HTML, CSS, and JavaScript editors with results that appear directly in the browser. Any changes can be viewed without saving files or refreshing pages manually. This tool is suitable for small experiments, learning layouts, and testing code pieces before they are put into a project.

Key points

The preview usually runs within the iframe to be isolated from the homepage
HTML, CSS, and JavaScript can be written in separate panels
JavaScript errors can be viewed through the console developer
Live previews speed up experiments but not replace real project testing
Save or copy the code before closing the tab so that the job is not lost
