How to prevent form submission while using HTML5 client-side form validation in Opera 11? Here is a sample test page: <section> <h2>Test</h2> <form> <input type="text" name="test" id="test" required/> <input type="submit" value="Test" /> </form> </section> Validation works in Opera 11, but when the button is clicked after entering a value, the browser submits the form. I want the browser to stay on the webpage always, which is good for client-side-only scripts, on the local hard drive, where there is no server, for example. When I add return false; or try to prevent the form from submitting,

I want to determine that the browser of the client machines in Opera or not using JavaScript, how to do that? The navigator object contains all the info you need. This should do: navigator.userAgent.indexOf("Opera"); Now that Opera uses the Chrome rendering engine, the accepted solution no longer works. The User Agent string shows up like this: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.52 Safari/537.36 OPR/15.0.1147.132 The only identifier for Opera is the OPR part. Here's the code I use , which should match the old Opera or the new

I am developing a web app for offline use, thus I need to use the application cache functionality. Everything works great on Chrome (15.0.874.106) but is doesn't work on Firefox (7.0.1) and Opera (11.52). This is my cache manifest file cache.manifest.php (I have reduced it to the bare minimum): <?php header("Cache-Control: max-age=0, no-cache, no-store, must-revalidate"); header("Pragma: no-cache"); header("Expires: Wed, 11 Jan 1984 05:00:00 GMT"); header('Content-type: text/cache-manifest'); ?>CACHE MANIFEST CACHE: /app/common/css/reset.css /favicon.ico And this is the first 4 lines of the

I was using the Wingdings font in the CSS for some symbols like a pencil and a home icon. It worked on IE, Chrome and Safari but not in Firefox and Opera. I googled it but did not find any better solution. Why doesn't it work in Firefox? I do need to use those icons, is there any way to use Wingdings in Firefox? Mozilla and Opera are standard-compiliant. Wingdings is not standard (what a surprise coming from Microsoft) because not mapped to Unicode, and so should never be used on a website. However, do not despair, most symbols are available in Unicode : check http://www.alanwood.net/demos

I can create CSS gradients in IE6/7/8/9/FF3.6+ and Chrome (see below). My question is: How would one create a gradient in Opera? .gradient{ /*Mozilla Firefox 3.6*/ background-image: -moz-linear-gradient(top, #dcdcdc, #c6c6c6); /*Webkit aka Google Chrome*/ background-image: -webkit-gradient(linear,left bottom,left top,color-stop(0, #c6c6c6),color-stop(1, #dcdcdc)); /*Internet Explorer 6,7 and 8*/ filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#dcdcdc', endColorstr='#c6c6c6'); /*Internet Explorer 8 only*/ -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='

This question already has an answer here: Can I hide the HTML5 number input’s spin box? 14 answers Just looking to remove these arrows, convenient in certain situations. I would like to preserve the browser's awareness of the content being purely numeric however. So changing it to input[type="text"] is not an acceptable solution. Now that Opera is webkit based, this question is a dulpicate of: Can I hide the HTML5 number input’s spin box? JayD I've been using some simple CSS and it seems to remove them and work fine. input[type=number]::-webkit-inner-spin-button, input[type=number]::-webkit
