Mozilla has launched a new project named Thimble as part of their Webmaker platform.
You also get the ability to instantly share your creations with your friends and family. Mozilla hosts the web pages for you.
Mozilla spoke about Thimble:
Thimble is webmaking made easy. It’s an intuitive visual editor that lets you write and edit HTML right in your browser, preview and correct your work, and then publish and share fully functional web pages with a single click. Thimble removes many of the barriers for novice users trying to learn code, and includes a series of starter projects and templates to help anyone get started quickly.
