Why isn't text hovering working on my asp.net project? - html

Question

This hovering idea works fine when i use it saperately on a small single page, but when I use it on my project, its not working.
Here's the code:
<%# Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="WebForm4.aspx.cs" Inherits="WebRole1.WebForm4" %>
<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
<style>
#sel>a: hover #span1 {
display: block;
}
#sel>a{
position: relative;
color: rgba(255,255,255,1);
text-decoration: none;
background-color: rgb(0, 148, 255);
font-family: 'Yanone Kaffeesatz';
font-weight: 700;
font-size: 3em;
display: block;
padding: 4px;
-webkit-border-radius: 8px;
-moz-border-radius: 8px;
border-radius: 8px;
-webkit-box-shadow: 3px 10px 55px 14px rgba(51,39,51,1);
-moz-box-shadow: 3px 10px 55px 14px rgba(51,39,51,1);
box-shadow: 3px 10px 55px 14px rgba(51,39,51,1);
margin: 100px auto;
width: 160px;
text-align: center;
-webkit-transition: all .1s ease;
-moz-transition: all .1s ease;
-ms-transition: all .1s ease;
-o-transition: all .1s ease;
transition: all .1s ease;
top: 0px;
left: -1px;
}
#sel>a:active {
-webkit-box-shadow: 0px 3px 0px rgba(219,31,5,1), 0px 3px 6px rgba(0,0,0,.9);
-moz-box-shadow: 0px 3px 0px rgba(219,31,5,1), 0px 3px 6px rgba(0,0,0,.9);
box-shadow: 0px 3px 0px rgba(219,31,5,1), 0px 3px 6px rgba(0,0,0,.9);
position: relative;
top: 6px;
}
</style>
<div id="sel">
<a href="webform1.aspx" >Private Album!</a>
Public Album!
</div>
<span id="span1">
Apple.
</span>
</asp:Content>
What i want is whenever I hover to, private album or public album, it should show Apple. Otherwise, nothing. But it keeps showing Apple on the lower left corner of the screen. What is wrong?

Answer 1

Your CSS selector is wrong.
Instead of this:
#sel > a:hover #span1
use this
#sel > a:hover + #span1
Selectors reference: http://www.w3schools.com/cssref/css_selectors.asp
And the "Apple" is still visible, because you should hide it from the beginning like this:
#span1 {display: none;}
