Starting a new project to create a fresh website.
It seems like many people are leaning towards CSS3 and AJAX, neglecting browsers without JavaScript support. They resort to workarounds like enabling CSS3 through JavaScript in older browsers.
Is this the recommended approach today?
My recommendation is to embrace the concept of "progressive enhancement":
Progressive Enhancement involves building each layer (content, followed by markup, styles, and behavior) on top of the next, ensuring that the essential content remains accessible for less capable browsers and devices. It's not about specific technologies like JavaScript, CSS3 Animations, or icon fonts. At its core, Progressive Enhancement is about starting with the content when designing a webpage.
Begin with simplicity, and incorporate Unobtrusive JavaScript and Css3 in a way that allows users to navigate and use the website even if these features are not supported.
The necessity of handling older browsers, such as IE versions below 9, and implementing advanced features not supported by them will determine the approach you need to take. If accommodating these older browsers is a requirement and complex functionalities are necessary, utilizing libraries that simulate these new features may be the solution. On the other hand, if there is no need to cater to older browsers or implement intricate features, then there may not be an issue at all. For a quick overview of browser support for specific features, you can refer to .
When it comes to cross-browser development, the consideration of JS and CSS3 support, fallback options, workarounds, and degradation all boil down to a matter of time and money. Sometimes, accommodating older or less common browsers can consume a significant portion of your development timeline. As we all know, time equals money. So, is it worth investing this much time in catering to browsers that may not even make up a substantial portion of your website's visitors (i.e., potential customers)?
For instance, currently, even IE8 only holds 4.31% market share. And don't forget, it does support JS.
