边框border通常简写为"border:1px solid red;"但其实一个完整的border边框其实是由1.border-width/*边框宽度*/,2.border-style/*边框样式*/,3.border-color/*边框色彩*/三大属性构成构成;
border边框方位分为border-top/*边框上方*/border-bottom/*边框底部*/border-left/*边框左边*/border-right/*边框右边*/;
边框属性样式整理：border-style:none;/*无边框*/border-style:hidden;/*隐藏边框*/border-style:dotted;/*点状虚线*/border-style:dashed;/*块状虚线*/border-style:solid;/*实线*/border-style:double;/*双线*/（至于border-style:groove;border-style:ridge;border-style:inset;border-style:outset;效果用到较少，通常solid,dashed,none）;
