55	55	How Tabs Should Work	Tabs in browsers (not browser tabs) are one of the oldest custom UI elements in a browser that I can think of. They’ve been done to death. But, sadly, most of the time I come across them, the tabs have been badly, or rather partially, implemented. So this post is my definition of how a tabbing system should work, and one approach of implementing that. But… tabs are easy, right? I’ve been writing code for tabbing systems in JavaScript for coming up on a decade, and at one point I was pretty proud of how small I could make the JavaScript for the tabbing system: var tabs = $('.tab').click(function () { tabs.hide().filter(this.hash).show(); }).map(function () { return $(this.hash)[0]; }); $('.tab:first').click(); Simple, right? Nearly fits in a tweet (ignoring the whole jQuery library…). Still, it’s riddled with problems that make it a far from perfect solution. Requirements: what makes the perfect tab? All content is navigable and available without JavaScript (crawler-compatible and low JS-compatible). ARIA roles. The tabs are anchor links that: are clickable have block layout have their href pointing to the id of the panel element use the correct cursor (i.e. cursor: pointer). Since tabs are clickable, the user can open in a new tab/window and the page correctly loads with the correct tab open. Right-clicking (and Shift-clicking) doesn’t cause the tab to be selected. Native browser Back/Forward button correctly changes the state of the selected tab (think about it working exactly as if there were no JavaScript in place). The first three points are all to do with the semantics of the markup and how the markup has been styled. I think it’s easy to do a good job by thinking of tabs as links, and not as some part of an application. Links are navigable, and they should work the same way other links on the page work. The last three points are JavaScript problems. Let’s investigate that. The shitmus test Like a litmus test, here’s a couple of quick ways you can tell if a tabbing system is poorly implemented: Cha…	2015	Remy Sharp	remysharp	2015-12-22T00:00:00+00:00	https://24ways.org/2015/how-tabs-should-work/	code
