我嘗試用影像制作一個 3 列網格，以便一些文本覆寫這些影像。為此，我找到了一個線性漸變的示例：
.card__content {
position: absolute;
background: linear-gradient(to top, rgba(0, 0, 0, 0.85), transparent);
}
所以在 HTML 中我有下一個：
<body>
<div class="container">
<div class="row">
<div class="col-lg-4 col-md-4 col-xs-12 thumb">
<div class="thumbnail" style="position:relative;">
<img src="1.jpg" align="left" class="img-rounded img-responsive">
<div class="card__content">
<h3>Matricaria is a genus of flowering plants in the chamomile tribe within the sunflower family</h3>
</div>
</div>
</div>
<div class="col-lg-4 col-md-4 col-xs-12 thumb">
<div class="thumbnail" style="position:relative;">
<img src="2.jpg" align="left" class="img-rounded img-responsive">
<div class="card__content">
<h3>Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari</h3>
</div>
</div>
</div>
<div class="col-lg-4 col-md-4 col-xs-12 thumb">
<div class="thumbnail" style="position:relative;">
<img src="3.jpg" align="left" class="img-rounded img-responsive">
<div class="card__content">
<h3>Cirsium arvense is a perennial species of flowering plant in the family Asteraceae</h3>
</div>
</div>
</div>
</div>
</div>
但是這個漸變并沒有粘到影像的末端，而是向右爬升。并且縮略圖的邊框不會延伸到塊的所有長度，盡管它沒有漸變。這是它現在的樣子。 圖片
請幫忙！

我做了一些改變：
.card__content {
position: absolute;
background: linear-gradient(to top, rgba(0, 0, 0, 0.85), transparent);
height: 100%;
display: flex;
align-items: center;
padding: 10px;
color: #fff;
}
.thumbnail {
display: inline-block;
border: 0;
}
.thumbnail img {
width: 100%;
max-width: 100%
