Sarah,

I was in a meeting with several interface designers where the topic of links and buttons came up. I think it was also unclear to them exactly when to use either buttons and links. Like you, they felt quite certain about some situations, but there were others they were less certain about.

Based on the way you view the usage of links and buttons, I would think buttons would be what you want to use in both situations. Neither situation leads to the user going to another page. The first situation just is a quick side trip to complete a task which ends up leading you back to the same page. The other situation seems just to perform actions on the page. If you are using ARIA though, you may want to look over the design patterns. It is possible that your second situation may fit better with another design pattern--like accordions.

I've not seen or heard a clear concise description of when to use links or buttons. In fact, the reason the designers ended up discussing the topic is because I asked them how they made that decision.

My own opinion tends to be that , if it is unclear, that would be a great time for user testing. However, if you can't conduct user testing, another good approach is to come up with your own approach and apply it consistently across your application interface. If it turns out the approach is not quickly intuitive, it at least means that once the user figures it out one place that they will know how it works across the rest of the application. And if you can't get the data you need to make the decision now, at least you can do something to lessen the impact if the guess is wrong. Also, it means if you have to fix it later, you will find it easier to locate where you need to apply the fix.

I wish you the best of luck with your button-link dilemma. I would be interested in hearing how you decide to resolve it.

Thanks,
Tim

Subject: [WebAIM] The buttons versers links debate

Hi everyone,

I'm trying to clarify when we should use a button rather than a link so that we can use the two consistently and provide the most appropriate experience to AT users.

Most of the time this is pretty simple: Use a link when it takes the user to another page, and use a button where the action is creating, adding, editing or deleting something. But there are a few scenarios I'm still struggling with and would like your advice on, particularly from what a screen reader user would expect or look for in these situations.

Situation 1) 

We have an 'Email to a friend' button (or link?) which opens an overlay which acts like a modal dialog. The user can then enter the appropriate details to send their information to a friend and submit (which definitely should be a button). Selecting the link that triggers this overlay is not actually editing any data at this point, its just showing some additional view/content and moving focus, so would this be classified as an internal link, or a button because the user is making an action to do something even though it is not modifying any data?

Situation 2)

We have a long form that is split into sections, and these sections collapse and expand as the user moves thorough the process on a single page. However the user can edit a section already completed using an 'Edit' link (or button?) Upon selecting this, the section expands and allows the user to edit the information they originally provided. My concern here is that all that happens by pressing this button did is expand information and display the appropriate form fields again. The user has not actually at this point edited any data. I don't think this can be considered an internal link either. The page unfortunately would not work at this point without JavaScript (a decision out of my control) in case this would be a deciding factor.

I would be interested to know which you think would be best in each case. Does anyone know of a good resource that defines when to use a link or button. My google searches have so far had mixed results. There's also the 'close' link debate to add to the overall confusion.

Thanks,
Sarah
