Description

I am using Opera 12.14 and getting an error from jquery about invalid value for property zoom usage in jquery 1.7.2 and also in 1.9.1.

Additionally I am seeing warnings about box-sizing.

I have printed the error console messages generated by this simple example within this example.

Please provide a test case at http://jsfiddle.net. It's really hard to tell what's the problem from a description so general.

Also, note that Opera complains about a lot of CSS properties, i.e. all it doesn't recognize, including prefixed values. This is Opera's problem, jQuery can do nothing about that.

http://jsfiddle.net/SYEPx/

This jsfiddle is almost the same test case I provided with jsbin.

Is the zoom related error killing the script or does jquery still continue to function? Since these css properties are injected, can this injection not take place if the browser is Opera?

Some lines of interest are: 1518, 1512, 1456, 1504, and 1495

You just pasted the output from Opera Dragonfly console, we need an actual test case so that we can reproduce it ourselves. Please, prepare a minimal example exhibiting a problem on jsfiddle.

As for the errors, unrecognized CSS properties never stop any browser from parsing further CSS rules, this is how CSS works. These errors are completely harmless.

Besides, this info is outdated, the zoom property is defined in CSS3 so it's perfectly standard now.

I'm grateful for your work on this and that you are taking the time to look at this issue, but I don't understand why you are dismissing it.

If you run either of those test cases in Opera you will get those errors. That is the simplest test case possible. The mere inclusion of jquery produces those errors and warnings.

Yes, I have done some further testing and I concur that the CSS error does not break the library, but it would still be nice to not see ten error messages every time the page using jquery loads.

The problem is nothing really can be done on jQuery's end about it. jQuery performs some support tests to know what it can rely on. All of these tests are performed on dummy divs that are removed from the DOM after testing is complete.

In cases where sth is really applied to DOM elements, like zoom set to 1 in old IE, it's enclosed within if checks so these changes are not applied to Opera.

Moreover, regular Opera users don't use the web console so it affects only developers.

BTW, most of errors in your jsFiddle test case come from jsFiddle itself, not jQuery. Also, 10 errors is not a lot, especially that most of them are vendor-prefixed ones that Opera really shouldn't complain about.

Also, all of this will be gone with the next Chromium-based Opera.

True point about the Opera overhaul. Thank you for your time and your efforts.
