Why is opera animation so slow?

由 感情迁移 提交于 2019-12-24 12:14:22
问题 It seems as though opera doesn't play nice with multiple animations going on simultaneously, check out this theme I'm building. I've made a preloader which scatters the images outside body in random places then animates each of them into place in intervals of 0.1 seconds with the animation taking 0.8 seconds. Here's the function I made: function ea_preload_scatter() { if(item.length) { var scatter = $(window).height() + $(window).width(); item.addClass('loading').each(function() { var

Speed Dial Icon in UC browser

由 佐手、 提交于 2019-12-24 11:14:44
问题 in Opera, the tag <link rel="apple-touch-icon" href="...."> is displayed in speed dial, but How can I set image in my website to show in speed dial of UC browser ? 回答1: Apparently this is not possible. UC browser seems to always use a default picture for Speed dial and Home screen. I have run the compatibility test of RealFaviconGenerator, which uses almost all known techniques to get a favicon: favicon.ico file, PNG icons, Apple Touch icon, Windows 8 tiles with and without browserconfig.xml

How to exclude added to Array methods from processing in “for..in” loop? (javascript)

由 淺唱寂寞╮ 提交于 2019-12-24 03:12:53
问题 I've added some useful helpers to Array (such as toSource() for Opera). And now for..in returns the functions with normal properties. I'm using for..in now, because the code is easier to read with it. And it's a native functional of js, so must be faster. But adding type checks in loop makes it easier to use classic for(;;) . Is there any methods to avoid for..in enumerate functions ? Cross-browser work is not very necessary (must work in Opera), but speed is important. Thank you. Edit: Is

Image source update in JavaScript with Opera

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-24 01:06:34
问题 I am loading remote images periodically with an Image object to be later drawn on a canvas. The Image object is created in JS only, it doesn't exist in DOM. The code is working fine with Chrome and Firefox. In Opera the problem is that the browser seems to always switch to "loading mode" whenever image source is modified, i.e. the cursor changes to the "waiting" one and Opera adds "Elements: X/Y" to the address bar. Here's the testing code: http://jsfiddle.net/nZntU/3/ Does anyone know any

Chrome & Opera radio box-shadow is square - Any workaround?

由 亡梦爱人 提交于 2019-12-23 16:43:43
问题 Chrome and opera both have bug in the styling of radio inputs, so that the shadow appears around a square box, rather than the native element. Firefox: Chrome & Opera: Does anyone know of a workaround for this, rather than just removing shadows for chrome & opera? 回答1: Wrap the radio element in a div, and set that div's overflow to hidden, and border-radius to 100px. Then set the radio input to display block, and no margin. <div class="radio_contain"> <input type="radio" id="r1" name="r1"> <

how to format input placeholder text for the Opera browser?

由 ◇◆丶佛笑我妖孽 提交于 2019-12-23 11:46:38
问题 I have styled placeholder text with CSS using the psuedo elements and pseudo classes below. This gets the job done on all major browsers but Opera. My understanding is Opera does not support styling placeholder text. Does anyone know of a way to style Opera input placeholder text? CSS ::-webkit-input-placeholder { color: red; font-size: 10px; } ::-moz-placeholder { color: red; font-size: 10px; } :-moz-placeholder { color: red; font-size: 10px; } :-ms-input-placeholder { color: red; font-size:
