Unix Compatible

UNIX was developed by AT&T Corporation’s Bell Laboratories in the late 1960s as a result of efforts to create a time-sharing computer system. In 1969 a team led by computer scientists Ken Thompson and Dennis Ritchie created the first version of UNIX on a PDP-7 minicomputer. Apple created and maintains a commercial version of the Unix-based OS, which is now the famed macOS.

Linux (Debian/Ubuntu, CentOS/RHEL)

The Linux OS was developed by Linus Torvalds in 1991, which sprouted as an idea to improve the UNIX OS. He suggested improvements but was rejected by UNIX designers. Therefore, he thought of launching an OS, designed in a way that could be modified by its users.

MS Windows

Microsoft Windows, also called Windows and Windows OS, computer operating system (OS) developed by Microsoft Corporation to run personal computers (PCs).

Mac OS X

Mac OS X (with X representing Roman numeral ten) is an operating system for Apple’s Macintosh computers. In addition to many distinct end user functionalities, it supports multiple development technologies including UNIX, Java, the proprietary Cocoa and Carbon runtime environments, and a host of open source, Web, scripting, and database applications.

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
