The Responsive Hover Paradigm
CSS transitions and animations provide web designers with a whole slew of tools to spruce up our designs. Move over ActionScript tweens! The techniques we can now implement with CSS are reminiscent of Flash-based adventures from the pages of web history.
Pairing CSS enhancements with our :hover pseudo-class allows us to add interesting events to our websites. We have a ton of power at our fingertips. However, with this power, we each have to ask ourselves: just because I can do something, should I?
Why bother?
We hear a lot of mantras in the web community. Some proclaim the importance of content; some encourage methods like mobile first to support content; and others warn of the overhead and speed impact of decorative flourishes and visual images. I agree, one hundred percent. At the same time, I believe that content can reign king and still provide a beautiful design with compelling interactions and acceptable performance impacts. Maybe, just maybe, we can even have a little bit of fun when crafting these systems!
Yes, a site with pure HTML content and no CSS will load very fast on your mobile phone, but it leaves a lot to be desired. If you went to your local library and every book looked the same, how would you know which one to borrow? Imagine if every book was printed on the same paper stock with the same cover page in the same type size set at a legible point value… how would you know if you were going to purchase a cookbook about wild game or a young adult story about teens fighting to the death?
For certain audiences, seeing a site with hip, lively hovers sure beats a stale website concept. I’ve worked on many higher education sites, and setting the interactive options is often a very important factor in engaging potential students, alumni, and donors. The same can go for e-commerce sites: enticing your audience with surprise and delight factors can be the difference between a successful and a lost sale.
Knowing your content and audience can help you decide if an intriguing experience is appropriate for your site; if it is, then hover responses can be a real asset.
Why hover?
We have all these capabilities with CSS properties to create the aforementioned fun interactions, and it would be quite easy to fall back into some old patterns and animation abuse. The world of Flash intros and skip links could be recreated with CSS keyframes. However, I don’t think any of us want to go the route of forcing users into unwanted exchanges and road blocking content.
What’s great about utilizing hover to pair with CSS powered actions is that it’s user initiated. It’s a well-established expectation that when a user mouses over an object, something changes. If we can identify that something as a link, then we will expect something to change as we move our mouse over it. By waiting to trigger a CSS-based response until a user chooses to engage with a target makes for a more polished experience (as opposed to barraging our screens with animations all willy-nilly). This makes it the perfect opportunity to add some unique spunk.
What about mobile, touch, and responsive?
So, you’re on board with this so far, but what about mobile and touch devices? Sure, some devices like the Samsung Galaxy S4 have some hovering capabilities, but certainly most do not. Beyond mobile devices, we also have to worry about desktops with touch capabilities. It’s super difficult to detect if a user is currently using touch or hover. One option we have is to design strictly for touch only and send hover enhancements to the graveyard. However, being that I’m all “fuck yeah hovers!,” I like to explore all options. So, let’s examine four different types of hover patterns and see how they can translate to our touch devices.

Changing text color on hover is something we’ve done for a while and it has helped aid in identifying links. To maintain the
