Since launching Google Chrome last September, we received a number of questions from webmasters and web developers about how to make their sites look great in Google Chrome. The questions were very insightful and illuminating for the Chrome team, and I want to respond with a few helpful tips for making your site look stellar in Google Chrome.

Detecting Google Chrome

Most sites will render the same in both Safari and Google Chrome, because they're both WebKit-based browsers. If your site looks right in Safari, then it should look right in Google Chrome, too.

Since Chrome is relatively new, many sites have confused Google Chrome with another browser. If your site doesn't look quite right in Chrome but works fine in Safari, it's possible your site may just not recognize Chrome's user-agent string.

As platforms and browsers adopt WebKit as their rendering engine, your site can detect and support them automatically with the right JavaScript checks. Commonly, sites use JavaScript to 'sniff' the navigator.userAgent property for "Chrome" or "Safari", but you should use proper object detection if possible. In fact, Gmail has been detecting WebKit properly in Chrome since day one!

If you must detect the user-agent type, you can use this simple JavaScript to detect WebKit:

var isWebkit =
  navigator.userAgent.indexOf("AppleWebKit") > -1;

Or, if you want to check that the version of WebKit is at least a certain version—say, if you want to use a spiffy new WebKit feature:

var webkitVersion =
  parseFloat(navigator.userAgent.split("AppleWebKit/")[1]) ||
  undefined;
if (webkitVersion && webkitVersion > 500 ) {
  // use spiffy WebKit feature here
}

For reference, here are a few browser releases and the version of WebKit they shipped:

BrowserVersion of WebKit
Chrome 1.0525.19
Chrome 2.0 beta530.1
Safari 3.1525.19
Safari 3.2525.26.2
Safari 4.0 beta528.16


We do not recommend adding "Google" or "Apple" to your navigator.vendor checks to detect WebKit or Google Chrome, because this will not detect other WebKit or Chromium-based browsers!

You can find more information about detecting WebKit at webkit.org.

Other helpful tips
  • Google Chrome doesn't support ActiveX plug-ins, but does support NPAPI plug-ins. This means you can show plug-in content like Flash and Java in Google Chrome the same way you do with Firefox and Safari.
  • If text on your site looks a bit off, make sure you provide the proper content type and character encoding information in the HTTP response headers, or at the beginning of your pages, preferably near the top of the <head> section.
  • Don't put block elements inside inline elements.
Wrong:   <a><div>This will look wrong.</div></a>

Right:     <div><a>This will look right!</a></div>
  • If your JavaScript isn't working in Google Chrome, you can debug using Chrome's built-in JavaScript debugger, under the "page" menu -> 'Developer' -> 'Debug JavaScript' menu option.
To help webmasters and web developers find more answers, we created a support center and forum specifically to answer your questions. Of course, if you find something you think is really a bug in Chrome, please report it to us!

Help us improve Google Chrome!

If you'd like to help even more, we're looking for sites that may be interested in allowing Google to use their site as a benchmark for our internal compatibility and performance measurements. If you're interested in having Google Chrome development optimized against a cached version of your site, please contact us about details at chrome-webmasters@google.com.

Please keep the feedback coming, and we'll keep working to improve Google Chrome!

As part of our efforts to make search results more useful to our users around the world, we’re announcing the international availability of rich snippets. If you’ve been following our blog posts, you already know that rich snippets let users see additional facts and data from your site in search results.

For example, we recently launched rich snippets for recipes which, for certain sites, lets users see quick recipe facts as part of the snippet and makes it easier to determine if the page has what they are looking for:


We’ve had a lot of questions on our blogs and forums about international support for rich snippets - and we know that many of you have already started marking up your content - so today’s announcement is very exciting for us.

In addition to adding support for rich snippets in any language, we have published documentation on how to mark up your sites for rich snippets in the following languages: simplified Chinese, traditional Chinese, Czech, Dutch, English, French, German, Hungarian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, and Turkish. (You can change the Help language by scrolling to the bottom of the help page and selecting the language you want from the drop-down menu.)

We encourage you to read the documentation to take advantage of the different types of rich snippets currently supported: people profiles, reviews, videos, events and recipes. You can also use our testing tool (in English only, but useful to test markup in any language) and start validating your markup to make sure results show as you would expect.

Finally and as you’ve probably heard by now (several times), we’re taking a gradual approach to surface rich snippets. This means that marking up your site doesn’t guarantee that we’ll show rich snippets for your pages. We’re doing this to ensure a good experience for our users; but rest assured we’re working hard to expand coverage and include more web pages.
