The WYSIWYG Web Builder website has been updated! All pages—over 600 of them—have finally been converted from a static/absolute layout to a flexible layout. This means the site now looks much better on both desktop and mobile devices.
Much of the content has also been refreshed. Tutorial texts and images have been reviewed, headings and titles are now properly structured, and the overall content flow has been improved to enhance readability for both users and search engines (including AI-based indexing). 
The switch to a flexible layout also makes it much easier to maintain content and update the site’s style (planned for a future update).
If you notice anything I may have overlooked, please let me know so it can be fixed.
