消除連結虛線框

/* Remove dotted outline on links
----------------------------------------------- */
a {
outline: none; /* for Firefox */
AsYouWish:expression(this.onFocus=this.blur()); /* for IE */
}

AsYouWish顧名思義，就是要命啥名都可以，同樣的效果，網路上有人將它命為
noFocusLine:expression(this.onFocus=this.blur());
有的命為
blr:expression(this.onFocus=this.blur());
