14. forms adapt to touch : < ! - - D e f a u l t K e y b o a r d - - > < i n p u t t y p e = " t e x t " / > < ! - - N u m e r i c K e y b o a r d - - > < i n p u t t y p e = " n u m b e r " / > < ! - - N u m b e r K e y b o a r d - - > < i n p u t t y p e = " t e l " / > < ! - - U R L K e y b o a r d - - > < i n p u t t y p e = " u r l " / > < ! - - e - m a i l K e y b o a r d - - > < i n p u t t y p e = " e m a i l " / > < ! - - P a t t e r n K e y b o a r d - - > < i n p u t p a t t e r n = " [ 0 - 9 ] * " t y p e = " t e x t " / >
15. tables try to avoid them o v e r f l o w : s c r o l l adapt to touch :
16. tables native scroll inside elements ( ) adapt to touch : source o v e r f l o w : s c r o l l ; - w e b k i t - o v e r f l o w - s c r o l l i n g : t o u c h ; / * n a t i v e l i k e s c r o l l * /

18. : h o v e r and mouseover events try to avoid them don't use them for displaying/perfoming critical inforation/tasks (for example tooltips and dropdown menus) provide alternatives adapt to touch :
19. : h o v e r and mouseover events no silver bullet for these try to use similar touch events adapt to touch :
20. UI components (like modals, image sliders, carousels, tabs, accordions etc.) do they enhance the experience or they just make things worst? are they really working on touch devices? do they respond to touch events? adapt to touch :
21. use a javascript touch library lean touch libraries full touch libraries
22. lean touch libraries fetures small footprint easier to use no UI components, just the touch events excellent solutions for small/middle projects
23. lean libraries (modular, works like jQuery) Hammer.js QUO.js
24. full touch libraries fetures large footprint more complete solutions (provide UI components and widgets) excellent solution for biggers projects/apps
25. full touch libraries jQuery mobile Sencha Touch jQT iUI
26. best practice start small, but if you really need something more complete, don't hesitate to use it! always try to load only what you really need/use
27. when in doubt, check how the "big" players do it Bootstrap Foundation Pure
28. follow the guidelines create your own! Android User Interface Guidelines iOS Human Interface Guidelines
29. touch devices can do more call or text < a h r e f = " t e l : + 3 0 6 9 4 8 1 2 3 4 5 6 " > + 3 0 6 9 4 8 1 2 3 4 5 6 < / a > < a h r e f = " s m s : + 3 0 6 9 4 8 1 2 3 4 5 6 " > + 3 0 6 9 4 8 1 2 3 4 5 6 < / a >
30. touch devices can do more capture images, video or sound using HTML forms < i n p u t t y p e = " f i l e " a c c e p t = " i m a g e ; c a p t u r e = c a m e r a " / > < i n p u t t y p e = " f i l e " a c c e p t = " v i d e o ; c a p t u r e = c a m c o r d e r " / > < i n p u t t y p e = " f i l e " a c c e p t = " a u d i o ; c a p t u r e = m i c r o p h o n e " / >
31. be a pioneer reward modern browser users use HTML5 (elements, attributes etc.) use CSS3 (gradients, shadows/text shadows, rgba, transitions, animations, fonts, etc.) SVG add a feature detection and adaptation strategy ( ) modernizr
32. be a pioneer use , or (or simply use a library like ) graceful degradation HTML5 geolocation API IndexedDB Web SQL Local Storage lawnchair
