html - 创建并排图像时出现问题(纯 HTML/CSS)

Question

我在 Up 和 down 投资组合行之间的垂直空间有问题。我在行中有一些不需要的空间这不是框内的边距或填充，我认为这个问题是针对 img 标签的谁能帮帮我？

.portfolio.row {
display: flex;
}
.col-4 {
  flex: 33.33%;
}
.portfolio > div img {
  width: 100%;
}

<div class="portfolio row">
  <div class="col-4" id="coffe">
    <img src="https://cdn.pixabay.com/photo/2019/05/07/16/19/strawberry-4186310_960_720.jpg" alt="Nature1">

Answer 1

我的猜测是它试图保持图像的纵横比。如果您添加 height: 100% 它确实有效:

.portfolio.row {
display: flex;
}
.col-4 {
  flex: 33.33%;
}
.portfolio > div img {
  width: 100%;
  height: 100%;
}

<div class="portfolio row">
  <div class="col-4" id="coffe">
    <img src="https://cdn.pixabay.com/photo/2019/05/07/16/19/strawberry-4186310_960_720.jpg" alt="Nature1">
