IE 6 position does not support the fixed attribute solution_html/css_WEB-ITnose

Another problem is thrown: IE7 already supports position:fixed, but IE6 does not. The solution to this problem is as follows:

Now there is an element whose id is element , it needs to achieve a fixed effect. We want it to be used under normal browsers and also want it to work normally under IE 6, then we can use CSS hack:

#element {position: fixed;top: 450px; /* 其他浏览器下定位，在这里可设置坐标*/_position: absolute; /*IE6 用absolute模拟fixed*//*IE6 动态设置top位置*/_top: expression(eval(document.documentElement.scrollTop) +  450); }

In this way, the element can be fixed at 450 pixels from the top. You can also add the following code to achieve the effect of removing page jitter:

*html body{background-image:url(about:blank);background-attachment:fixed;}

In the previous article, through _top Set the CSS style, then how to modify the expression style:

var domThis=$(this)[0];domThis.style.setExpression('top', 'eval((document.documentElement).scrollTop + ' +  50 + ')');

In this way, you can achieve the purpose of modification.
