如何使缩略图中的图像占据缩略图的整个空间,以便叠加div(" 11月和#34;)和slideToggle div(" STEM&中的女性和女孩) #34;)不要坚持下去?
我使用jQuery和Bootstrap。当用户将鼠标悬停在图像上时,slideToggle会向上滑动,然后在鼠标离开时消失。但它并不适合图像; 11月也没有覆盖。
$(document).ready(function () {
$('.thumbnail').hover(function () {
$('.slider', this).slideToggle('fast');
});
//$('.thumbnail').hover(function () {
// $('.slider', this).animate({
// opacity: 0.75,
// height: "toggle"
// }, 750, function () {
// //Animation complete.
// });
//});
});

.womens-overlay {
position: absolute;
background: rgba(0,0,0,1);
top: 0;
right: 0;
padding: 2%;
width: 35%;
color: #FFFFFF;
}
/*Removes the automatic thumbnail frames.*/
.thumbnail {
border: none;
box-shadow: none;
float: left;
position: relative;
margin: 5px;
color: #333;
}
.thumbnail img {
max-height: 100%;
max-width: 100%;
}
.thumbnail .slider {
border: none;
box-shadow: none;
display: none;
opacity: 0.8;
background: #D2D6E2;
width: 100%;
position: absolute;
bottom:4px;
padding: 5px;
}
.slider {
position: absolute;
padding-top: 0%;
}

<div class="col-sm-6 col-md-4">
<div class="image-box">
<div class="thumbnail">
<img src="Images/celebrating-women-in-stem.jpeg" />
<div class="womens-overlay">
<h3>November</h3>
</div>
<div class="slider">
<h2>Women & Girls in STEM Month</h2>
<h3>EVENT</h3>
<p>This November, we are celebrating women and girls in STEM. Come join us!</p>
<button type="button" class="btn btn-primary">Learn More</button>

添加每个功能,以便它可以在多个缩略图上运行。然后获取缩略图的高度并将.slider高度设置为相同。
$(document).ready(function () {
$('.thumbnail').each(function(){
// get height
var height = $(this).height();
// set slider height
$(this).children('.slider').css({'height':height+'px'});
$(this).hover(function () {
$(this).children('.slider').slideToggle('fast');
});
});
});
然后设置overflow:隐藏在.thumbnail上
.thumbnail {
border: none;
box-shadow: none;
float: left;
position: relative;
margin: 5px;
color: #333;
overflow: hidden;
}
