Web pages always have a top margin, and JS scripts can only be used in IE_html/css_WEB-ITnose

Recently, I need to create an effect. Click the button (picture) to hide the left menu and the Banner bar above
I copied a very simple example and modified it. I am basically satisfied, but there are the following problems:
1) Hide The Banner buttons (pictures) are not fully displayed because the showtop.html cannot always remove the top margin;
2) The JS that controls the image transformation and FrameSet size can only be applied under IE;
I hope you can give me some advice
(There are eight pages, a formal interface effect, the code is relatively simple, and it has an AR package, but the upload size is too small)

showtop.html is wrong
It is a modified version………………
Original version The CSS is not commented, there is no Tabletrtd in the Body, only a1f02c36ba31691bcfe87b2722de723b
<html> <head> <title>Frame Middle</title><style type="text/css">body { background-color:#000000; margin-top:0px; height:9px;}img { margin-top:0px;}</style> <script language="javascript"> function isShowtop() { if(window.parent.mainFrame.rows == "70,9,25,*,25") { window.parent.mainFrame.rows = "0,9,0,*,0"; document.images['topcontrol'].src='showtop.gif'; } else { window.parent.mainFrame.rows = "70,9,25,*,25"; document.images['topcontrol'].src='hiddetop.gif'; } } </script> </head> <body> <img id="topcontrol" src="hiddetop.gif" onclick="isShowtop()" /> </body> </html> 1. What is the top margin that the poster is referring to?
2. Modify two JSs
middle.html
<script type="text/javascript"> function isShowleft() { if (window.parent.window.document.getElementById("main").cols == "200,9,*") { window.parent.window.document.getElementById("main").cols = "0,9,*"; document.images['imghiddetop'].src = 'http://csdnimg.cn/bbs/m/i/yellow_1.gif'; } else { window.parent.window.document.getElementById("main").cols = "200,9,*"; document.images['imghiddetop'].src = 'http://csdnimg.cn/bbs/m/i/yellow_1.gif'; } } </script> --------------- ------------------------------------------
showtop.html
70,9,25,*,25 ==>70,14,25,*,25
<script type="text/javascript"> function isShowtop() { if (window.parent.window.document.getElementById("mainFrame").rows == "70,14,25,*,25") { window.parent.window.document.getElementById("mainFrame").rows = "0,9,0,*,0"; document.images['topcontrol'].src = 'http://csdnimg.cn/bbs/m/i/yellow_1.gif'; } else { window.parent.window.document.getElementById("mainFrame").rows = "70,14,25,*,25"; document.images['topcontrol'].src = 'http://csdnimg.cn/bbs/m/i/yellow_1.gif'; } } </script> PS:

showtop.html does not have a top margin under Firefox, but under IE there is

showtop.html does not have a top margin under Firefox, but it does under IE.
There is a default margin under IE.
Generally use the following to clear margins and eliminate differences, and then set all CSS:
* {margin:0;padding:0}

Thank you very much!
Actually, the so-called multi-browser operation is nothing more than doing some tricks on the frameset, it is just a grammatical issue.
Variable = window.parent.document.getElementById ('your frameset name');
Variable.cols="frame width change"; just write a judgment like this, it is very cheating...need If so, I can pass some JS for everyone to try. . .
