Legit CSS Frameworks
An evergreen list of free and open source CSS frameworks worthy of your time.
Three-hundred millis is three times greater than the ideal response time, which, in some user interfaces, could be too slow and cause frustration for users. The Google Voice mobile webapp ran into a similar challenge over a year ago and crafted a Fast Button workaround using some creative event handling a method they called “busting ghost clicks”, which allows click handlers to be used in conjunction with touch events.
A caveat to rejigging the event handling, however, is that zooming should be disabled entirely. If it is not, double-taps on the so-called Fast Button would not behave as mobile web users have come to expect, leading to a less awesome user experience. And though the Google workaround compensates for buttons, working with more complex controls and widgets or multi-touch gestures is likely to dredge up some painful and time-devouring edge cases to handle.
Nevertheless, recent advocacy for Mobile First (thanks Luke W) and Responsive Web Design seem to play well with the Fast Button workaround by making it possible to build a mobile web application that with a display adjusts intelligently to the viewport and with which zooming a page is not required.
In summary, the 300ms delay used in mobile devices for double-tap detection is three times greater than the ideal 100ms (or shorter!) delay in a UI and, though Google has a nice workaround it should only be used with caution, and only in mobile web apps that do not allow page zooming. And when you find yourself doing a lot of event handling on your own and wonder if there’s a better way, consider “stick with click”.
