CSS는 간단한 평면 버튼을 구현합니다.

<button id="btn">打印</button>

//js写法
$("#btn").css({
	"font-family": "&#39;微软雅黑&#39;,&#39;Helvetica Neue&#39;,Helvetica,Arial,sans-serif",
	"font-size": "13px!important",
	"height": "30px",
	"line-height": "18px!important",
	"padding": "3px 18px",
	"display": "inline-block",
	"vertical-align": "middle",
	"font-weight": "normal",
	"border-radius": "2px",
	"margin": "0 8px 0 3px",
	"border": "1px solid #3383da",
	"color": "#ffffff",
	"background-color": "#3383da"
});
