我无法将图像居中,此刻,它停留在左侧。这个概念是当我点击图像时,图像的较大版本会弹出我们。
HTML:
<div class="photoposition" style="cursor:pointer" onclick="showImage('imagesinsurgent/in21.jpg');">
<img src="imagesinsurgent/in21.jpg" class="scaledownlandscape"/>
<p class="photogalleryp"></p>
</div>
<div id="largeImgPanel" onclick="hideMe(this);">
<img id="largeImg" style="height: 100%; margin: 0; padding: 0;" />
</div>
CSS:
.photoposition{
width: 250px;
height: 250px;
margin-left: 53px;
float: left;
position: relative;
}
.scaledownlandscape{
width: 250px;
object-fit: scale-down;
display: block;
margin: 0 auto;
}
.divspan{
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
z-index: 1;
}
#largeImgPanel {
visibility: hidden;
position: fixed;
z-index: 100;
top: 0;
left: 0;
width: 500px;
height: 400px;
background-color: rgba(100,100,100, 0.5);
margin-top: 141px;
}
使用Javascript:
function showImage(imgName) {
document.getElementById('largeImg').src = imgName;
showLargeImagePanel();
unselectAll();
}
function showLargeImagePanel() {
document.getElementById('largeImgPanel').style.visibility = 'visible';
}
function unselectAll() {
if(document.selection) document.selection.empty();
if(window.getSelection) window.getSelection().removeAllRanges();
}
function hideMe(obj) {
obj.style.visibility = 'hidden';
}
答案 0 :(得分:2)
给#largeImgPanel
100%宽度并居中对齐内容
#largeImgPanel {
visibility: hidden;
position: fixed;
z-index: 100;
top: 0;
left: 0;
right: 0;
width: 500px;
height: 400px;
background-color: rgba(100,100,100, 0.5);
margin-top: 141px;
text-align: center;
}
