everyone! I recently find Grid is a perfect layout style, but browsers like Chrome or FireFox don't support it unless you do some flag settings.
So if I want to make a grid layout i must detect whether the browser support grid or not. If browser doesn't support it i will load css-grid-polyfill.js and implement it:
if (!Modernizr.**some_property**) {
require(["css-grid-polyfill.js"], function (){
console.log('css-grid-polyfill.js is loaded');
});
}
So the problem is what property of the Modernizr can tell whether browser support grid layout or not? Many thanks in advance!

I have a Xamarin forms app where I'm using ListViews to display some data, with pull to refresh enabled. When the ListView is pulled and starts the refresh it has its own spinner animation. However, this doesn't display when the page first loads, and so I've wired in a separate ActivityIndicator to indicate loading for just the first time. It's styled different though. I would prefer to use the ActivityIndicator, since it's what's used through the rest of the app, but I haven't found a way to disable the spinner animation on the ListView yet. Is it possible to disable it? Any suggestions would be appreciated, thanks!
There are a few ways I can think of to solve this.
Don't use Pull-to-refresh. Xamarin.Forms has this built in and you can't customize it without using renderers and altering controls. Instead, start your refresh another way (ToolbarItem, etc) and continue using your custom ActivityIndicator.
Customize the existing ListViews UIRefreshControl. You may be able to use a renderer or "Effect" to customize the RefreshControl being used by the native control. This would allow you to style it a little close to what your custom indicator looks like.
Change the color of the spinner. This is my least favorite option. You could workaround this by changing the color of the spinner to match the background so you don't see it.
I am fond of the type of side navigation menu that is common in mobile apps. An example is: http://www.jqueryscript.net/menu/jQuery-Animated-Side-Navigation-Menu-Plugin-Sidebar.html
Which works also for web pages. However, the vast majority of my page is in KendoUI, and I don't want to load another framework just for that.
Is there a combination of tricks with Kendo (draw control for example) that I could use to get the same effect?
Alternatively, I am all wet. I just want a quick way to have a "pop-up" of settings that are only occasionally used, and most of the time save the screen real-estate. So maybe just a button and a pop-up window is the correct approach?
Any advice?
I'm making a WebKit-based text editor app for Mac, and I need to find a way to zoom the document in and out.
I've seen this StackOverflow article here, it suggests just scaling the view that Webkit is rendered into. The problem is, since Webkit doesn't know about it, this breaks things like drag & drop and causes Javascript to report the wrong cursor locations. Unfortunately, for some reason, the Cocoa WebKit API only supports scaling text up or down, not the whole page.
Safari and Chrome are both able to do this properly. I've gone as far as to look through the Chromium source code to figure out how it's done, but unfortunately it's using a completely different cross-platform API.
Any advice would be greatly appreciated. I'm not opposed to using private APIs, if I can figure out how to use them in a safe way.

The APIs for doing this aren't currently public, but they've been around for years and aren't likely to change. You can find them in WebKit's WebViewPrivate.h header. You won't find that header on your system, so you'll have to redeclare those methods yourself in a category. Something like:
#interface WebView (Zoom)
- (IBAction)zoomPageIn:(id)sender;
- (IBAction)zoomPageOut:(id)sender;
- (IBAction)resetPageZoom:(id)sender;
#end
Another option is just to set the CSS zoom property on the html element in your editor. You can do that in markup (<html style="zoom: 1.5">) or in JavaScript (document.documentElement.style.zoom = "1.5"). That doesn't require using any private APIs.
I like the new New Project templates included in the ASP.NET MVC3 tools update, as presented at MIX 11 recently.
A basic site can be seen here:
http://mix11.haacked.com/
When I view the above site in Chrome, the HTML5 styles are visible - rounded corners and text shadow.
When I view the site in IE8 those styles aren't visible.
My question is, isn't Modernizr supposed to make these styles work in older browsers?
-Matt
Modernizer won't actually add missing functionality to a browser. Basically, you use it as a guide to tell you whether a browser supports a certain feature. In your case, you could have a CSS file which will compensate for browsers that don't support border radius:
.no-borderradius div {
/* properties for browsers that don't support border-radius */
}
The above is a total made-up example, I'm not sure 100% if it's correct, but check the documentation here.
So for IE8, you would need to display rounded corners using a different technique.
I want to set the color of my scrollbar and for it to work in firefox as well.
I read that scrollbar's are not part of the w3c standard and therefore their customizing are not supported in firefox. Well, there must be some way to get it working. Does anyone how to do it?
Short of faking your own scrollbar with JavaScript, it is impossible.
