1 fix problem:
We all know that the position:fixed problem is not supported under IE6! But I often use this attribute to fix a certain position of the floating menu. However, one problem is that this attribute is not supported under IE6! So what should I do? I found out that there is a way to solve the above problem by using hack techniques and expressions. We all know that there are many bugs under IE6 that have not been fixed. Of course, Microsoft cannot fix IE6 now, so many experts on the Internet research. Of course hacking is also a technology. Don’t think about hacking. ! ! Of course, you can use it without hacking! ! ! The fix solution is as follows:
*position:absolute;*top:expression(eval(documentElement.scrollTop+document.documentElement.offsetHeight-101))
The 101 in the code refers to the height of the floating menu! In this case, although IE6 supports the fix attribute, when we move the scroll bar to test, we still find that IE6 and 7 will have jitter bugs. The methods to fix IE6 7 jitter are as follows:
html,html body {background-p_w_picpath:url(about:blank);background-p_w_upload:fixed;}
In the past, I used a few 1px×1px transparent images to solve this problem, but I found that I can put an empty image wherever I can. Now there are no bugs so far. Compatible with browsers such as IE, Firefox, Google, etc.! ! !
2 To achieve the problem of translucency, you only need to add a line of code to the css.
background-color:#000; opacity:0.5;filter:alpha(opacity=50);
3 To solve the problem that the element cannot be clicked under IE6 7 due to the transparent flash covering the element, it can be solved by adding the following code to the element:
filter:alpha(opacity=0);*background-color:#000; position:relative; z-index:1000;
4 Solve the hack of floating menu scrolling with scroll bar under IE6
width:100%!important; width:auto; /*nav keep centered under IE6*/_position:absolute;_top:expression(eval(documentElement.scrollTop+130)); /*left and right sides*/ _position:absolute;bottom :0px;_top:expression(eval(documentElement.scrollTop+document.documentElement.offsetHeight-58)); overflow:hidden;left:0.1%;margin-left:10px;}/*At the bottom*/
5 The problem of ul li is like this under normal circumstances. I’m sorry, as if I can’t cut a picture here, I can’t put it in to describe it. Normally, it’s one line per line but under IE6 7 it’s skewed, so the solution must be display. :inline; this attribute can solve the problem! ! !
6 The height problem When you want the height of an element to increase with the increase of the content, do not set height: 100%; in this case, the background will not increase with the increase of the content, and it will be out of touch in the middle. Generally, the height is not set But when there is a need for height: 100%, in order to solve the above background problem, the following code can be used to solve it! !
body,html{height:100%;}
In this case, the height of the outermost layer will vary with the height of the body and document! The above problem can be solved!

10 Youku video address conversion: Sometimes the demand side gives us a Youku video address, but that video address has advertisements, but the demand side says I don’t want advertisements, so our conversion method here can first open Youku video and click "More "Multi" button and then copy the flash address first, such as this:
http://player.youku.com/player.php/sid/XMzMyNTQ2MjA4/v.swf We just need to convert like this and it will be ok http://player.youku.com/player.php/partnerid/XMTcxMg==/ sid/XMzMyNTQ2MjA4/v.swf add partnerid/XMTcxMg==
11. Sometimes we need to use anchor links, but sometimes anchor links cannot be used. We can use javascript to write a javascript.

JS
<script type="text/javascript"> function map(url){ var _url = document.location.href, surl = _url.split("#"), realUrl = surl[0] + url; location.href = realUrl; } </script>
