I liked how easy it was for me to learn jquery mobile and implement into my existing site. It's very intuitive and made building pages fast and simple.The transition between page elements felt a bit clunky sometimes but after some playing around with different animation speeds this didn't seem like an issue. It took sometime for me to fully understand what exactly you can do in jqm so there were instances where I thought something wasn't working as intended. But once I started looking at documentation and examples online I realized everything does work just fine! We have been able to build several mobile friendly applications using jqm which has helped us reach more customers who prefer browsing our website via their smartphones or tablets instead of laptops/desktops. The jQuery mobile is very easy to use, it has many features and works great with Bootstrap. I can't say anything about this, but there's nothing. It looks good, everything works fine and no problems at all. You can try the demo version. I have used jquery mobile for my work projects. I made an application using this which was really good. Now i am working on new project and currently using jquery mobile.
