The answer to that is around 1% of the time.
If you had an application bug which occurred 1% of the time, you’d fix it. No team I’ve come across would put up with that level of reliability.
With a Progressive Enhancement mindset, support actually means support. We’re not trying to create an identical experience: we’re creating a viable experience instead.
Also with Progressive Enhancement, it’s incredibly likely that your IE11 user, or your user on a low-powered device, or even your user on a poor connection won’t notice that they’re experiencing a “minor” experience because it’ll just work for them. This is the magic, right there. Everyone’s a winner.

If you treat data as a constraint in your design and development process, you’ll likely be able to brainstorm a large number of different ways to keep data usage to a minimum while still providing an excellent experience. Doing less doesn’t mean it has to feel broken.
This post was originally written in 2015, but upon re-reading it today, it still (just about) holds up, so I finally hit publish.
But there’s a difference between something degrading gracefully (the result) and graceful degradation (the approach).
This is how it goes. We put a load of shit into a single web page. This makes the page slow. Slow to load, slow to render. Slow.
Instead of getting rid of the shit, we blame the page refresh.
I would urge front-end developers to take a step back, breathe, and reassess. Let’s stop over engineering for the sake of it. Let’s think what we can do with the basic tools, progressive enhancement and a simpler approach to building websites. There are absolutely valid usecases for SPAs, React, et al. and I’ll continue to use these tools reguarly and when it’s necessary, I’m just not sure that’s 100% of the time.
This is a really nice write-up of creating an accessible progressive disclosure widget (a show/hide toggle).
Where it gets really interesting is when Andy shows how it could all be encapsulated into a web component with a progressive enhancement mindset
53% of mobile visits leave a page that takes longer than 3 seconds to load. That means that a large number of visitors probably abandoned these sites because they were staring at a blank screen for 3 seconds, said “fuck it,” and left approximately half way before the page showed up. The fact that the next page interaction would have been quicker—assuming all the JS files even downloaded correctly in the first attempt—doesn’t amount to much if they didn’t stick around for the first page to load. What was gained by putting the business logic in the front end in this scenario?
Everything you need to know about hyphenation on the web today, from Rich’s galaxy brain.
Hyphenation is a perfect example of progressive enhancement, so you can start applying the above now if you think your readers will benefit from it – support among browsers will only increase.
A fascinating look at the web today with IE8. And it’s worth remembering who might be experiencing the web like this:
Whoever they are, you can bet they’re not using an old browser just to annoy you. Nobody deliberately chooses a worse browsing experience.
The article also outlines two possible coping strategies:
- Polyfilling Strive for feature parity for all by filling in the missing browser functionality.
- Progressive Enhancement Start from a core experience, then use feature detection to layer on functionality.
Take a wild guess as to which strategy I support.
There’s a bigger point made at the end of all this:
IE8 is today’s scapegoat. Tomorrow it’ll be IE9, next year it’ll be Safari, a year later it might be Chrome. You can swap IE8 out for ‘old browser of choice’. The point is, there will always be some divide between what browsers developers build for, and what browsers people are using. We should stop scoffing at that and start investing in robust, inclusive engineering solutions. The side effects of these strategies tend to pay dividends in terms of accessibility, performance and network resilience, so there’s a bigger picture at play here.
A good talk from from Chris Ferdinandi, who says:
Hui-Jing talks through her process of building a to-do app on Glitch using a progressive enhancement mindset:
This aspect of Vue appeals to me more than the all-or-nothing vibe I get from React:
By enabling incremental adoption, Vue’s progressive nature means that individuals can start using it here and there, a bit at a time, without having to do massive rewrites.
