There are probably half a dozen or more stacks available that will help you put responsive tabs on your webpage. Michael wanted something simpler, something lightweight, so he developed Tably.

The first thing I noticed when I placed Tably on my Stacks page, was the fact that the tabs are activated by checkboxes. The first checkbox 'Enable Tab 2' is already checked. So what happens if I deactivate Tab 2? — I get a box with a coloured button in its title bar – interesting. You can activate up to ten tabs.

Now the thing that I like about Tably is its simple responsiveness – when the viewport shrinks to below a defined width, Tably morphs into an accordion. Again, nothing new – that's already been done. Recently, I went to purchase just such a stack. The thing that prevented me from doing so, was the fact that the accordion was heavily animated – each time you clicked on a minimised tab, the whole page jumped up and down, even if the content length was identical.

When Yuzool's Tably is minimised the tabs simply substitute their content. Obviously, if the content is different in length, the tab container will change its size, but instead of an irritating, nervous animation the change can be a simple swap, or the content can fade out and in – your choice. 

The animation can be set to one of four different speeds and the tab content can automatically cycle – again, with four different speeds. Tably will also let you define which of the ten tabs automatically opens when the page is loaded.

The remaining settings are for Tably's background colours – the background can be deactivated – and for the button colours. The buttons are rectangular 'ghost' buttons. There are no other options to alter their appearance.

Tably arrives with a second, bonus stack – Toggle, a stack that will flip your content at the click of a button. You can drop any combination of stacks into Toggle, including Tably, and have their content displayed on demand. Michael's example page displays a price list for a subscription-based service. Toggle flips over to display Monthly or Annual subscription prices.

There are just two settings for Toggle – the button labels and the button colours.

Toggle is responsive. It's interesting that, instead of changing size when the screen narrows, the buttons turn into a dropdown.

Two stacks for the price of one — can't be bad!
