输入框景背景透明：

<input style="background:transparent;border:1px solid #ffffff">

鼠标划过输入框，输入框背景色变色：

<INPUT value="Type here" NAME="user_pass" TYPE="text" SIZE="29" onmouseover="this.style.borderColor='black';this.style.backgroundColor='plum'" style="width: 106; height: 21" onmouseout="this.style.borderColor='black';this.style.backgroundColor='#ffffff'" style="border-width:1px;border-color=black">

输入字时输入框边框闪烁(边框为小方型)：

<Script Language="JavaScript">function borderColor(){if(self['oText'].style.borderColor=='red'){self['oText'].style.borderColor = 'yellow';}else{self['oText'].style.borderColor = 'red';}oTime = setTimeout('borderColor()',400);}</Script><input type="text" id="oText" style="border:5px dotted red;color:red" onfocus="borderColor(this);" onblur="clearTimeout(oTime);">

输入字时输入框边框闪烁(边框为虚线)：

<style>#oText{border:1px dotted #ff0000;ryo:e xpression(onfocus=function light (){with(document.all.oText){style.borderColor=(style.borderColor=="#ffee00"?"#ff0000":"#ffee00");timer=setTimeout(light,500);}},onblur=function(){this.style.borderColor="#ff0000";clearTimeout(timer)})};</style><input type="text" id="oText">

自动向下廷伸的文本框：
