CSS ホバー機能が「.Left」ではなく「.Footer」で機能するのはなぜですか? 何が問題を引き起こしているのかわかりません。コードの何が問題になっていますか? どんな助けでも大歓迎です!
CSS:
<style type="text/css">
.Footer {
opacity:0.5;
filter:alpha(opacity=50); /* For IE8 and earlier */
}
.Footer:hover {
opacity:1.0;
filter:alpha(opacity=100); /* For IE8 and earlier */
}
.Left {
opacity:0.5;
filter:alpha(opacity=50); /* For IE8 and earlier */
}
.Left:hover {
opacity:1.0;
filter:alpha(opacity=100); /* For IE8 and earlier */
}
.Header {
background-color: #000;
position: fixed;
height: 60px;
width: auto;
top: 0px;
left: 0px;
right: 0px;
}
.H1 {
position: relative;
height: 40px;
width: 440px;
left: auto;
right: auto;
top: 10px;
bottom: 10px;
margin-right: auto;
margin-left: auto;
}
.Footer {
position: fixed;
height: 63px;
width: 178px;
left: 15px;
bottom: 15px;
}
.Container {
background-color: #0F0;
position: relative;
height: 2000px;
width: 1020px;
z-index: -1;
margin-top: 75px;
margin-right: auto;
margin-left: auto;
}
.Left {
position: relative;
margin-bottom: 15px;
}
.Center {
position: relative;
margin-bottom: 15px;
margin-right: 15px;
margin-left: 15px;
}
.Right {
position: relative;
margin-bottom: 15px;
}
</style>
