Every website on the internet uses HTML language and relies on using an editor to build the website. The HTML editor is a platform to edit and create the website’s content.
A great way to make HTML content is often through a WYSIWYG editor, short for “What You See is What You Get.” These editors work similarly to a word processor, creating the HTML for you and giving you a preview of what to expect.
Additionally, we must remember that the WYSIWYG HTML editors are open-source products for everyone. With open-source HTML editors, the concept goes beyond being a fee-to-use software.
Open-source means users can access the program’s source code and undertake modifications depending on the circumstances. Some open-source WYSIWYG HTML editors also allow modified versions of their programs to be shared or sold as long as they are under the same licenses as their original counterparts.
The following are the best open-source WYSIWYG HTML editors you can use in your web design and development.
