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）;
