Browsers and Devices
At the front end, our extensions produce valid HTML5 and CSS 3.0, which are well supported by the vast majority of modern browsers and devices. We can't guarantee perfect results on older devices, but if you do notice a visual problem in a major browser on an important device, please contact us and we will try to fix it.
In the past some of our extensions used Bootstrap on the front end but it caused a lot of support issues, so we stopped using it. Our extensions no longer load or use Bootstrap at all, and work happily with or without any version of Bootstrap loaded.
In the more distant past some of our extensions used the MooTools library but we eliminated all usage of MooTools long ago. Our extensions no longer load or use MooTools at all, and work happily with or without any version of MooTools loaded.
