Open .html files on your Mac.

.html .htm

Web pages and email templates with tags, attributes and values in their own colors.

Loper is a free, minimal editor for macOS that opens HTML instantly and colors every part of the file, so you find the value you need at a glance and can fix it right there. No IDE, no project to load, no gray wall of text.
