What Dabblet is

Dabblet is a free, open-source web playground for quickly trying CSS and HTML snippets. Its preview updates while you edit, without a separate run command, and -prefix-free adds CSS prefixes automatically. The editor provides CSS, HTML, JavaScript, and result views with horizontal, vertical, or separate layouts. Inline previewers cover CSS values such as colors, lengths, durations, angles, easing functions, and gradients. Work can be saved in GitHub Gists, embedded on other websites, and shared. JavaScript inside script tags is not executed; the help page identifies inline event handlers as the current way to add JavaScript. Dabblet supports modern versions of Chrome, Safari, and Firefox, and documents shortcuts for saving, navigation, editing, indentation, and value changes. The service is frontend-focused and identifies Lea Verou as its maker. Dabblet is distributed under the NPOSL-3.0 license. Posted code remains owned by its poster, and no license is enforced on that code.
