Reusable tabs, no js appearance, and content jump

[necolas]

Some issues with the tabs that need to be considered:

• Styling of content without JS. At the moment you cannot see any tabs other than the first one when JS is disabled. They should all be visible by default.
• Content jumping. When you click on one of the tabs, the viewport jumps up sometimes as the content is hidden/show.
• Reusable tab component. The style of the tabs themselves should be independent of the js tabs because you might want to use them for main navigation too. As part of this we'll probably want a hz list mixin.

We could avoid reinventing the wheel by taking the good bits of the tab plugin from Bootstrap or existing jQuery plugins for this.

Agree on all counts. I think much of this can be addressed when the components are re-written as plugins.

@mathiasbynens If you've got any time to help out with this too, that would be awesome.

I once wrote my own jQuery tabs plugin for an old client project… I’ll see if I can modify it and open-source it.
