There’s a lot to learn about CSS3, and it can be overwhelming if you’re just catching yourself up with what’s going on around you. Let’s look at how CSS3 — even though it’s not supported by all browsers (like IE6) — can be pragmatically implemented into your website production process.
Progressive enhancement is a key concept to apply while we are in this transitional period where not quite all of our users use browsers that have CSS3 capabilities.
Progressive enhancement simply means we can provide an enhanced experience to users whose browser has more features than those that use non-modern browsers.
You create sites focused on universal design and accessibility: Make sure that users with older browsers can use the site, but also take advantage of browser features found in modern browsers like Chrome and Opera.
Websites no longer need to be pixel-perfectly identical on different browsers. Here’s an example that uses progressive enhancement: Github’s Plans & Pricing page.
Below is the page viewed in Google Chrome. Notice that buttons and other page elements use CSS3 (
gradient image values,
On IE7 — a browser that doesn’t have support for these CSS3 properties and values — the page looks like this:
The difference is subtle to most Internet users. What’s important is that the page functions as intended and is accessible to everyone.
The page just takes advantage of features that Chrome has that IE7 doesn’t. The web designer took advantage of IE’s proprietary
filter CSS property to render the color gradients, but didn’t try to render the rounded corners using CSS background images and CSS/HTML markup tricks to mimic
Progressive enhancement is a key enabler to using CSS3 in your web designs today.
Use Site Data to Make Decisions
Web designers should use data to make sound judgments. When working on a client’s site, it’s always useful to get some kind of data set about their current users.
Google Analytics (for example) is a completely free website analytics tool. Even running it for a week on the client’s website can help you gain vital information. Website analytics can show you what browsers are being used to access the web property, and from there, you can then see what percentage of browsers can handle CSS3.
If you are seeing high percentages of Chrome and Safari (both use the WebKit layout engine) then you should rejoice because they can handle a lot of what CSS3 has to offer. A very rough approximation of a general demographic suggests that Safari and Chrome have about 7% and 10% (respectively) of the browser market. Those numbers can be a lot higher or a lot lower depending on the site and the audience it draws in. Going on those numbers, though, means that about 1 in 5 people have the ability to experience CSS3.
Add to that the popular open source browser, Mozilla Firefox (and browsers like SeaMonkey and Flock that use the Mozilla layout engine), and the return of investment starts to look better.
Then, with IE9 being released this month, it just makes sense to use more CSS3 than not. IE9 isn’t perfect — and it isn’t as feature-rich as Chrome and Firefox when it comes to CSS3 and HTML5 (and thus, we would still need progressive enhancement even if we disregard older versions of this browser line) — but it’s a step in the right direction.
Learn and Practice CSS3 on Your Own Site
As a web designer, there’s a very big chance that you run your own portfolio website. Redesigning your site with CSS3 and progressive enhancement let’s you learn through real world, practical experience.
Using CSS3 on your own website also gives you the opportunity to show off your newly acquired skills to prospective clients.
Many pioneering CSS3 techniques and experiments began on the portfolio websites of web designers and web developers. It’s a fertile environment for innovation.
By looking at website statistics and data, you can make decisions on what CSS3 specifications you can implement on a site-to-site basis. Leveraging progressive enhancement makes pragmatic implementation of CSS3 something you can do today, even when many Internet users are still using browsers that can’t render CSS3.
We are at a stage in web design where different designs between browsers is accepted — and even expected. If you’re still hesitant about using CSS3 in your project work, don’t be. Embrace CSS3.
