Modernizr Documentation. What is Modernizr? Modernizr is a small piece of Java. Script code that automatically detects the availability of next- generation web technologies in your user's browsers. Rather than blacklisting entire ranges of browsers based on “UA sniffing,” Modernizr uses feature detection to allow you to easily tailor your user's experiences based on the actual capabilities of their browser. With this knowledge that Modernizr gives you, you can take advantage of these new features in the browsers that can render or utilize them, and still have easy and reliable means of controlling the situation for the browsers that cannot. What is feature detection?

Why it’s is better than the rest. Over the years there have been many methods to detect Flash player versions and embed Flash movies into HTML documents. What browser am I using? Is my browser up to date? Find these things out and more! Including JavaScript, Cookie, Flash, and Java detection. Scalable Vector Graphics (SVG) is a Web graphics language. SVG defines markup and APIs for creating static or dynamic images, capable of interactivity and animation.

In the dark ages of web development, we often had to resort to UA sniffing in order to determine if their user's would be able to make use of Awesome- New- Feature. In practice, that means doing something like the followingif (browser === ? We are using Awesome- New- Feature?

That could very well be the case - today. But what if the next version of that browser adds support for Awesome- New- Feature? Now you have to go back and audit your code, updating every single place that you are doing this check. That is assuming that you have the time to find out about every feature update for every single browser. Worse still, until you realize that it actually works in the newest version, all of those users back at the office get. The. Old. Lame. Experience, for no reason whatsoever.

Those users - given a substandard website for apparently no reason - can actually go into their browser and OS settings and change the name of the browser (or user- agent - what we compare against in code when performing a UA sniff) to whatever they would like. At that point - your code is meaningless. You are blocking out users who may actually support all of your features, and possibly letting those in who don't. Nearly everyone gets a broken experience. There has to be a better way!

Determines how Windows handles memory for the browser when minimizing. What is my browser detects the details instantly. Internet web browser version, flash version, java version and other browser details will be displayed immediately.

There is, and it is called Feature Detection, and it looks more like thisif (Modernizr. New. Feature) . So now as soon as your least favorite browser adds support for Awesome- New- Feature! No more having to update, ever.

The code ends up being similar, but much more clear to its actual intention. Downloading Modernizr. A lot has changed since the last version of Modernizr. There no longer is a single, base modernizr. Instead, just head over to the Download page as you could have previously, and select the features you want to use in your project. This way we can provide the smallest file possible, which means a faster website for you. Once you have done that, just hit the Build button and you’ve got your own custom build of Modernizr, hot off the presses!

You may notice that in addition to the Build output, where you have been able to download custom builds one at a time for years now - there are two new options. Command Line Config.

Since 3. 0, Modernizr also ships its build system as a node module on npm. That means that you can quickly create multiple builds of Modernizr for different projects, without even having to open a new browser tab. Once you have npm installed, you can install the Modernizr command line tool by runningnpm install - g modernizr. Now you are ready to get your start making your custom build! You can download the configuration file from the build menu (under . This will give you a JSON file that you will give to the Modernizr module to make your custom build. Note that you will need to give the command line config the file path to the configuration you downloaded from the site.

In the above example, we are running the modernizr command from the same folder that we downloaded the modernizr- config. Grunt Config. If you do not want to manually run your build from the command line every time you update your site, you also have the option to download a Grunt task to do it for you. This configuration file can be used with grunt- modernizr to automatically build your custom version. Just add it to your Gruntfile, and you are off to the races. Note that you will need to update the provided configuration file with paths to the dev.

File and output. File. More documentation is available for grunt- modernizr here. Configuration Options. In addition to the available options and feature detects, there are a handful of additional configuration options.

Prefix - default: . This means adding the class for each feature when it is supported, and adding it with a no- prefix when it is not (e. This makes it super simple to add features in via progressive enhancement! Say you include Modernizr's detection for CSS gradients. Depending on the browser, it will result in either < html class=. Now that you know those two states, you can write CSS to cover both cases. Consider the hidden detect, which adds a . Little Shop Of Horrors Cracked Servers there.

If you wanted to use that specific detection, you could use the following as your configuration. This lets hide certain elements that should only be exposed in environments that execute Java. Script. If you want to disable this change, you can set enable. JSClass to false in your config. Classes. If you are using a class.

Prefix, such as supports- , then you must include that prefix on your html element. This is does not effect the .

JSClass to false in your configuration. Using Modernizr with Java. Script. The Modernizr object. Modernizr keeps track of the results of all of it's feature detections via the Modernizr object.

That means that for each test, a corresponding property will be added. You just have to test for truthiness in your code to figure out what you want to doif (Modernizr. New. Feature) . One thing to notice is that the names of feature detect functions are always lowercased when added to the Modernizr object. That means that Modernizr.

Tuesday will not exist, but Modernizr. Since we only look at the returned value from any feature detection function, you do not need to actually use a function.

For simple detections, just passing in a statement that will return a boolean value works just fine. Modernizr. add. Test('has. Jquery', 'j. Query'inwindow). Just like before, when the above runs Modernizr. Query has been included on the page. Not using a function saves a small amount of overhead for the browser, as well as making your code much more readable.

Finally, you also have the ability to pass in an object of feature names and their tests. This is handy if you want to add multiple detections in one go. The keys should always be a string, and the value can be either a boolean or function that returns a boolean. By default, it does this detection on a div elementhas.

Event('blur')However, you are able to give an object as a second argument to has. Event to detect an event on something other than a div. Event('devicelight', window)Modernizr. Modernizr. mq(mq)Modernizr. Modernizr. mq('(min- width: 9. For example, in older Firefox.. Sizing')returns 'Moz.

Box. Sizing' In newer Firefox, as well as any other browser that support the unprefixed version would simply return box. Sizing. Any browser that does not support the property at all, it will return false. By default, prefixed is checked against a DOM element. If you want to check for a property on another object, just pass it as a second argumentvar r. AF = prefixed('request.

Animation. Frame', window). If you need the actual name of the property, pass in false as a third argumentvar r. AFProp = prefixed('request. Animation. Frame', window, false). Prop === 'Webkit.

Request. Animation. Frame'One common use case for prefixed is if you're trying to determine which transition end event to bind to, you might do something like.. End. Event. Names = . Properties can be passed as both the DOM style camel. Case or CSS style kebab- case. Modernizr. prefixed.

CSSValue. Modernizr. CSSValue(prop,value)Modernizr. CSSValue is a way test for prefixed css properties (e.

It is simply an array of kebab- case vendor prefixes you can use within your code. Some common use cases include Generating all possible prefixed version of a CSS propertyvar rule = Modernizr.
