If you have a component with tabs in your non-mobile website you don’t think about “how will those look on smaller screens?” You already know it’s going to look ok but switching between tabs will not feel comfy in most cases. Instead you should wonder “how do I make it work well on mobile?” or “how to make tabs usable on smaller screens?”. Creating responsive tabs is important to make the website usable in every environment.
Depending on a number of tabs in your component, making it look and work just like in desktop may not always be the best idea. You can make tabs a little bigger to make them easier to hit with your fingers. Sure, that’ll work on a component with 2 or 3 tabs (with small, non-descriptive captions on them). What if your component have more then 3 tabs or even better – dynamic number of tabs? Predicting the numbers and making silly styling adjustments for each of them is like ignoring a huge hole in your room and stepping over it, everytime you want to get out. 😀
The perfect solution doesn’t need to be a hard one if you start thinking in Responsive Web Design and It doesn’t require any bloated jQuery plugin. While we’re still going to use a little bit of jQuery, It will only be used to switch between CSS classes.
