Front end frameworks have been around for a while now and a quick search will return a myriad of different examples, all of which seem to offer very similar advantages to both developer and end user. I played around with a few examples and settled on Foundation, simply because I managed to get up and running quickly. This is an important point to note given that research time is limited, making fiddling around with any kind of installation an unwanted hassle. Further, as tools and environments move forward it’ll be the simple to install and deploy that will succeed simply because developers want to get playing with the functionality rather than digging into configuration files.
To conclude. I think I’m converted to the front end framework in certain applications, although hand coding the big three isn’t going anywhere just yet.
