The Editor is an online application, meaning that you do not have to download a program to build your website; however, it is recommended that you work with one of the following browsers:
Safari browsers - known issues with borders
Throughout several versions, Safari browsers have exhibited occasional difficulties rendering border styling and border colors correctly. If you experience such issues on a Mono-built website, be aware that they are caused by issues native to the Safari browsers and not by how published websites are generated by the Mono Editor.
Please note that the Editor is only fully operational when used on a desktop computer although you may be able to use parts of the interface on tablet and mobile devices, depending on your browser and operating system.
