Older browsers won't render the effects, but the pages shouldn't break, either.Īs long as you're aware of the limitations of older browsers, and you check to make sure that your site looks acceptable with them, you can have plenty of (serious) fun experimenting with new features, progressively enhancing the experience for visitors with the most up-to-date browsers. As for CSS3, browsers ignore properties or values that they don't understand, so you can feel safe using many new features, such as rounded corners and drop shadows, to enhance the look of web pages in the latest browsers. If a browser doesn't recognize the specialized input types, such as email, url, number, and range, it simply treats that type as a standard text-input field. For example, you can start implementing the new HTML5 form features in your websites without worrying that those features will break in older browsers. The other important factor is that HTML5 is deliberately designed to be backwardly compatible. All the latest versions of the major browsers—including Internet Explorer—support large parts of HTML5 and CSS3. While bugs and differences between browsers are unlikely to go away in a hurry, what's different now is that the browser manufacturers are competing to implement common standards, rather than going their own separate ways. The greatest barrier to adopting new techniques has been buggy implementation and inconsistencies between browsers. Where's the fun in that? It sounds like a nightmare. Designs need to look just as good on a tiny screen as a desktop monitor. And in case you hadn't noticed, huge numbers of people now access the web on their mobile phones and tablets. What's more, the web standards body, the World Wide Web Consortium (W3C), is encouraging web designers to start using the new features even though the specifications are still evolving. Forget predictions that HTML5 won't be ready until 2022 and that CSS3 is merely a pipe dream. After years of very little happening, web designers are suddenly caught up in a maelstrom of change.
