HExT is a tool designed to allow for quick experimentation
with HTML and CSS.
Users are provided with separate boxes in which to edit CSS and HTML, and several pre-loaded images to play with. As the user edits, their code is stored in a cookie in the browser. No information is stored on the server. This is a purely temporary tool, and safe to use as a sandbox for school projects and CSS testing, as long as cookies are enabled in your browser.
HExT was developed in 2010 as a more flexible alternative to W3Schools "TryIt! Editor". Syntax highlighting is provided by the CodeMirror project.
