Identify HTML5 Tags:HTML5 added a number of semantically labeled tags, such as Copy Code code as follows: The effect came out, do not want to also know that these several browsers are not recognized these tags, so just appear a line of text: Nav aside;In modern browsers, these two are normal block-level tags, so there are line-wrapping.I risked trying to try and give Nav and aside labels a s

performance. Math-multiple mathematical operation types. Regexp-regular expression. String-string processing, including generating a giant "tagcloud" code, decompressing the compressed Javascript code, and so on. In addition to the comparison above, the Statistical Chart below compares the performance of various browsers more intuitively. Although the string generated by the test is almost impossible in most production cases, I am still quite vocal

development library want to understand some of its implementation mechanisms, how does jQuery achieve this?View jQuery's latest source code (version 1.2.2). From row 1,195th to line 1205, it is a function for judging the browser. As you can see, jQuery uses the second method above, that is, using user-agent to determine the user's browser and version.Frankly speaking, at first I was surprised to know the types and versions of browsers with just five

How to achieve transparent background, text opaque, compatible with all browsers?What we usually say about adjusting transparency, in fact, is to adjust the opacity in the style, as in the example:Open PS, on the layers panel, you can see a menu that sets the opacity of the layer, from 0% (fully transparent) to 100% (completely opaque).There are 3 ways to implement a transparent CSS method, and the followi

Solve the problem that css3 rounded corners are compatible with all browsers. This article mentions a good solution to achieve cross-browser rounded corners. Some time ago, I often receivedBorder-radiusAttribute to achieve rounded HTML elements. You may know that the border-radius attribute of css3 is supported by browsers such as safari, Firefox, and chrome, but IE does not support it for some reason.

If you choose a browser other than Internet Explorer, or you write code for a non-Microsoft browser, you need to use different code. In fact, this is the simple line of code shown in Listing 1: var xmlHttp = new XMLHttpRequest object;. This much simpler code creates the XMLHttpRequest object in Mozilla, Firefox, Safari, Opera, and virtually all non-Microsoft browsers that support Ajax in any form or mode. 　　Combined The key is to support all

This article mainly introduces the CSS browser incompatibility reason analysis, has a certain reference value, now share to everyone, the need for friends can refer to Browser incompatibility, we are certainly very repugnant, often we just go to do patching, but forget the more important thing, that is to trace the source, to avoid similar incompatibility again. In the next, summed up a few HTML coding elements, I hope to show you:1. The size of the text itself is not compatible. The same is th

New version of BKJIA: Mozilla has finally released Firefox 4-generation browsers to a large number of users. What we want to do here is a large-scale browser benchmark test.

debugging, but Firefox sometimes does not support some elements and attributes. What's worse is that "when performing control verification, when verification fails, the focus is removed from the verified control, and the focus of the other three browsers is not moved ". In fact, the most depressing thing about me is the page cache. Sometimes the "Running cache pages instead of the latest pages" problem occurs during debugging, so I often don't know
