我希望settingsBox
元素浮在画布上而不是它下面。我可以在样式表中更改哪些内容以达到预期效果?
<!DOCTYPE html>
<html>
<head>
<style>
body {
text-align: center;
margin: 0px;
}
#fullCanvas {
width: 100%;
height: 100%;
background-color: blue;
z-index: 0;
}
#settingsBox {
width: 400px;
height: 400px;
z-index: 1;
border: 2px solid black;
background-color: lightgrey;
padding-left: 0;
padding-right: 0;
margin-left: auto;
margin-right: auto;
margin-top: 25px;
}
</style>
<script>
function hideSettings() {
document.getElementById('settingsBox').style.visibility = 'hidden';
}
</script>
</head>
<body align="center">
<canvas id="fullCanvas">
This site requires html5 etc
</canvas>
<div id="settingsBox" onclick="hideSettings()">
Settings go in here. Click to hide
</div>
</body>
</html>
答案 0 :(得分:3)
首先,你有一点拼写错误,你写了一个位置:abolute for your fullCanvas,它应该是:
#fullCanvas {
position: absolute;
// your other styles
}
并且为了使z-index工作,你必须将各个元素的位置设置为绝对,固定或相对,这意味着你必须将settingsBox设置为position:relative,如下所示:
#settingsBox {
position: relative;
// your other styles
}
除此之外你的代码对我来说很好看
