在jQueryMobile框架中，默认按钮是横向独占根据屏幕宽度自适应的。
ui-btn——声明为按钮显示；
ui-shadow——让元素在划过时有阴影的效果；
ui-icon-*——jQueryMobile内置图标属性；
ui-btn-icon-notext——让按钮隐藏文字；另外的ui-btn-icon-*属性还有：
ui-btn-inline——在一行中显示多个按钮，即内联样式；
data-role="controlgroup"——将几个按钮以组的方式显示；
data-type="horizontal"——指明承载的子元素以水平方式排列；
ui-btn-a——白色主题的按钮；
ui-btn-b——黑色主题的按钮；
更多按钮的属性请查看jQueryMobile的API
