中心和中间位置，与窗口滚动无关

Question

I'm using the 'read more' buttons on this page to display previously (display:none) divs: http://apexhubmobile.co.uk/corporate-friends

The problem is when they display they force the window to the top of the page to view it, I tried changing the positioning to fixed and the box then didn't display properly until I scrolled a little.

My aim is for the hidden div to show up in the center & middle of the window regardless of how far down the page the user is. Here's a few excerpts of code.

<style>
.b1 {float:left;width:292px;background-color:#F2F2F2;margin:0 4px 5px;vertical-align:middle;border:1px solid grey;line-height:0 !important;}
.b2 {line-height:0 !important;}
.f1 {z-index:999;background-color:white;border:1px solid; grey; position:fixed; top:50%; left:50%; height:430px; width:900px; margin:-215px 0 0 -450px; display:none;}
.f2 {width:100%;background-color:silver;text-align:center; font-size:1.2em; color:white;}
.f3 {position:absolute; right: 0;top: 2px; font-size:0.8em;color:black;}
.f4 {width:35%; height:410px; float:left; display:inline-block;padding:15px 0 0 15px;text-align:center;}
.f5 {width:35%;float:left;text-align:center;position:absolute;bottom:15px;}
.f6 {width:65%;float:left;display:inline-block;padding:15px;}

<div id="s38" class="f1"><div class="f2">SEMINARS@THIRTYEIGHT
<span class="f3">&nbsp;&#91; <a href="#" onclick="jQuery('#s38').css('display', 'none');">close</a> &#93;&nbsp;</span></div><div class="f4">

Any ideas?

Answer 1

Your problem is that you set attribute "href='#'" so it try to target # anchor when you click on it, but as it is not found, it just set the scroll to the top.

You can remove href attributes and style in CSS cursor pointer for your links.

Or set anchors onto your page.

PS : or maybe use event.preventDefault(); with jQuery
