1. What is jqMobi
jqMobi is a JavaScript framework developed by appMobi for HTML5 browsers and mobile devices. It is an extremely fast query selection library that supports W3C queries.
Version
jqMobi source code was originally launched in January 2012. It is based on the MIT/X11 license and is hosted on GitHub. Developers can participate and continuously improve the framework through plug-ins.

Intel Acquisition
Intel February 22, 2013 Acquired HTML 5 mobile application company appMobi Html5 development tools and related employees, but did not acquire the startup. After the acquisition, jqMobi was renamed appframework. The later jqMobi is actually appframework. This move is one of Intel's actions to build its own mobile application developer tool suite. In order to provide more support for html5 and CSS3, the processor giant may consider building corresponding hardware.
2. The difference between jqMobi and jQuery
jqMobi is developed by appMobi, while jQuery is a product of jQuery Foundation. The jqMobi source code is rewritten based on the jQuery source code, but the two are different products. jqMobi is smaller, faster, and has different compatibility.
Smaller size
After compression, jqMobi’s files are smaller than jQuery
Fast speed
According to the data of JSPerf test , which is 3 times faster than jQuery on Android and 2.2 times faster on iOS. The tested speed is 3 to 5 times that of JqueryMobile, and the speed is similar to SenchaTouch
Compatibility
jqMobi is mainly aimed at operating systems with WebKit browsers (such as Android, iOS and the latest version Designed for BlackBerry OS), jqMobi 2.0 is compatible with IE10 (windows8 and windows phone8 platforms); while jQuery is compatible with more browsers (such as ie6).
3. The composition of jqMobi

html5的div元素默认一行不可以放两个。div是一个块级元素,一个元素会独占一行,两个div默认无法在同一行显示;但可以通过给div元素添加“display:inline;”样式,将其转为行内元素,就可以实现多个div在同一行显示了。

html5中列表和表格的区别:1、表格主要是用于显示数据的,而列表主要是用于给数据进行布局;2、表格是使用table标签配合tr、td、th等标签进行定义的,列表是利用li标签配合ol、ul等标签进行定义的。

固定方法:1、使用header标签定义文档头部内容,并添加“position:fixed;top:0;”样式让其固定不动;2、使用footer标签定义尾部内容,并添加“position: fixed;bottom: 0;”样式让其固定不动。

html5中不支持的标签有:1、acronym,用于定义首字母缩写,可用abbr替代;2、basefont,可利用css样式替代;3、applet,可用object替代;4、dir,定义目录列表,可用ul替代;5、big,定义大号文本等等。

HTML5中画布标签是“<canvas>”。canvas标签用于图形的绘制,它只是一个矩形的图形容器,绘制图形必须通过脚本(通常是JavaScript)来完成;开发者可利用多种js方法来在canvas中绘制路径、盒、圆、字符以及添加图像等。

html5废弃了dir列表标签。dir标签被用来定义目录列表,一般和li标签配合使用,在dir标签对中通过li标签来设置列表项,语法“<dir><li>列表项值</li>...</dir>”。HTML5已经不支持dir,可使用ul标签取代。

3种取消方法:1、给td元素添加“border:none”无边框样式即可,语法“td{border:none}”。2、给td元素添加“border:0”样式,语法“td{border:0;}”,将td边框的宽度设置为0即可。3、给td元素添加“border:transparent”样式,语法“td{border:transparent;}”,将td边框的颜色设置为透明即可。

因为html5不基于SGML(标准通用置标语言),不需要对DTD进行引用,但是需要doctype来规范浏览器的行为,也即按照正常的方式来运行,因此html5只需要写doctype即可。“!DOCTYPE”是一种标准通用标记语言的文档类型声明,用于告诉浏览器编写页面所用的标记的版本。
