Easy to use! I am not very good at CSS coding but this kit has helped me fix many bugs in my website and it's been easy with such great documentation. Nothing bad comes out as far as i know since I started using them. If you are new to bootstrap or css then definitely use this tool. This will help your work load dramatically because of their amazing support team. They are always there whenever we need any assistance. We have fixed several issues and bugs by using these kits. We were able to make our site look like an android phone app which had some serious issue before they used their services. I like the fact that it is very easy to use and has all the elements that I need. I also like the fact that it is very user-friendly. I dislike that you have to pay for it. I would like to try it for free but it is not available. I'm solving the problem of having a website that is both modern and user-friendly.
