I'm developing a mobile site using AngularJS (v 1.5) and it doesn't load in Opera mini. So I started searching and found one article about how Opera mini is a proxy based server and it stripes maximum JavaScript data.
But except that one article, I haven't seen it stated explicitly that Opera mini isn't supported, so I'm a bit confused.
I know Angular 2 is supposed to be released with the view of mobile-first architecture, but does Angular 1.x support opera mini?
Thanks in advance.
It seems Opera mini no longer supported by AngularJS. Check this:

Edited:
Quoting from AngularJS FAQ (latest stable v1.5):
What browsers does Angular work with?
We run our extensive test suite against the following browsers: the
latest versions of Chrome, Firefox, Safari, and Safari
for iOs, as well as Internet Explorer versions 9-11. See
Internet Explorer Compatibility for more details on supporting legacy
IE browsers.
If a browser is untested, it doesn't mean it won't work; for example, older Android (2.3.x) is supported in the sense that we avoid
the dot notation for reserved words as property names, but we don't
actively test changes against it. You can also expect browsers to work
that share a large part of their codebase with a browser we test, such
as Opera > version 12 (uses the Blink engine), or the various Firefox
derivatives.

I have written a bootstrap page and it works just perfectly on all browsers i have tested....except ie11 with enterprise mode on.
It seems to stretch everything to full width as if my screen is a giant phone. Im sure other things are broken in it but thats the first thing you see.
Anybody have any ideas if Bootstrap and Enterprise mode dont play well? I see some posts asking the question and some responses saying to force ie9 10 or edge mode but that wont work with enterprise mode as it overrides that...ie think.
From MSDN:
Enterprise Mode, a compatibility mode that runs on Internet Explorer 11 on Windows 8.1 Update and Windows 7 devices, lets websites render using a modified browser configuration that’s designed to emulate either Windows Internet Explorer 7 or Windows Internet Explorer 8, avoiding the common compatibility problems associated with web apps written and tested on older versions of Internet Explorer.
And from Bootstrap:
On Windows, we support Internet Explorer 8-11
So if you are running Enterprise mode in IE7 mode, Bootstrap will do all sorts of odd things. The solution would be to run in IE8 mode which may fix a lot of issues or don't add this site to the list.
Our company develops ERP and CRM, and so far our products support IE and Firefox. Now we want to support Chrome, Safari and even Opera. Is there any comprehensive materials that introduce browser compatibility of JS and CSS? thks!
theres the mozilla dev-center that has a great CSS- and JavaScript-reference. Every entry has information about browser compatibility.
For a quick overview, you cauld also take a look at caniuse.com (CSS and JavaScript) that provides simple tabular lists for the different features.
I've been coding the front-end for over a decade and a half now, and things seem to get better over time in regards to cross-browser compatibility. I've found that if I write and test my code using Firefox, most everything will work flawlessly on Chrome, Opera, Safari and the only thing you'll end up having to debug would be MSIE. 10 years ago I would have told you to code and test using MSIE and debug your code in the end with Netscape.
But yeah, if you follow this, you'll find it easier to make all your scripting and markup fully cross-browser compatible with no bugs at all. Enter IE9, of course, a different monster altogether.

"Comprehensive" can change overnight, but there is a great deal of information available.
If your products work for the latest version of Firefox, Chrome, Safari, and Opera will work without major flaws most of the time. If your markup is invalid, you are using many vendor-specific extensions, or you are using cutting-edge features, this may not be the case.
Can't every mobile browsers support JavaScript? Which language/technology are used in mobile browsers pages? I mean the mobile websites...
I know XHTML is used much, What are the rest?
iPhone and default Android and BlackBerry all use WebKit. Opera and FireFox offer mobile browsers as options.
Windows Phone uses a version of IE9.
All of above support JavaScript. You can see phones from 2+ years ago that have browsers w/o JS, but they're not common anymore.
Most modern smartphones' browsers are based on Webkit - the same engine that powers Chrome and Safari. IE on Windows Phone 7 and Firefox are supposed to be standards-compliant too. Opera does have some support but don't count on it too much.
So, yes, they do support Javascript, and the technology stack is the same as for desktop ones (HTML, CSS, javascript). You even get broader support for HTML5/CSS3 in them.
Older phones, however, are a completely different story, and believe me, you don't want to go there :)
The Zepto.js website says:
Zepto.js is a minimalist JavaScript framework for mobile WebKit browsers, with a jQuery-compatible syntax.
Is it only recommended for use with apps that will be used on mobile devices or can it also be used in traditional computer browser web apps as well? What are the downsides of doing so?
I use jQuery a lot in my regular web apps (for computer browsers) and I've realized (after finding Zepto.js) that I don't always use all of jQuery's features, so Zepto.js is perfect for what I do.
Also, why is there focus on the 'WebKit' engine? Does it not work with mobile Internet Explorer on Windows Phone 7, Firefox Mobile on Android or Opera Mobile?
EDIT: The presence of $.os.android in addition to $.os.ios indicates that there is support for non-iOS platforms, so the last question is answered!
EDIT (final): I guess the real question is "Can the Zepto.js library, intended for use on mobile WebKit-based browsers, be used as a lighter-weight alternative to jQuery for the desktop also?" The answer is no.
Note: This answer is old, and not up to date anymore. Yes, Zepto started as a webkit-only, mobile-specific framework, but it has evolved since then as EBarr points out below.
So always check Zepto's website for the most up-to-date information.
Not to sound too harsh, but did you click the big button on the site to see the presentation?
You basically already answered the questions:
Yes, it's for mobile devices. Support for swipe and tap events doesn't exactly make sense on a desktop computer, where you use a mouse.
Yes, it's for WebKit specifically, because that's what's most used for mobile browsing. That means no support for IE/Firefox/Opera - mobile or desktop. As the presentation says, "No one is running IE6 on an iPhone". Most desktop-browser JS libraries exist specifically to eliminate browser differences. Zepto does the opposite.
jQuery is an offroad truck: Enormous but very capable both on- and off-road.
Zepto is a Formula-1 car: Small, fast, and built exclusively to be great on the racetrack, so it won't work right in any other situation.
It seems that Zepto's purpose has evolved. The site now notes :
Note that some optional features of Zepto specifically target mobile
browsers; as the original project goal was to specifically provide a
leaner alternative to jQuery on for the mobile web.
It lists the following as target platforms (note the inclusion of desktop browsers):
Browser support
Primary (100% support)
Safari 6+ (Mac)
Chrome 30+ (Windows, Mac, Android, iOS, Linux, Chrome OS)
Firefox 24+ (Windows, Mac, Android, Linux, Firefox OS)
iOS 5+ Safari
Android 2.3+ Browser
Internet Explorer 10+ (Windows, Windows Phone)
Secondary targets (fully or mostly supported)
iOS 3+ Safari
Chrome <30
Firefox 4+
Safari <6
Android Browser 2.2
Opera 10+
webOS 1.4.5+ Browser
BlackBerry Tablet OS 1.0.7+ Browser
Amazon Silk 1.0+
Other WebKit-based browsers/runtimes
EDIT
List above updated to reflect reality as of January 2013.
What is the current support for the slice method?
Currently Chrome 6+, FF 4+:
Firefox 3.6+ (partial file support, but not .slice() yet)
Firefox 4+ (full file support, though I'm unsure which beta this was added in)
Chrome 6+ (full file support)
Of course this list will become outdated, hopefully soon. There's a test available at html5rocks.com for others to test their browser as new releases happen as well.
