我有3个Desktop格式的图像大小不相同，如何获得相同的大小？然后在移动格式中，我希望它通过占据整个宽度来重叠。
我试过使用flex-direction: column，但它不起作用。我的代码使用flexbox。
.background-color {
background-color: #f05f40;
}
h2 {
text-align: center;
padding-top: 2%;
margin-top: 0;
}
.row {
display: flex;
width: 100%;
text-align: center;
}
.content {
justify-content: space-around;
padding: 0 10px;
}
img {
height: 200px;
object-fit: cover;
object-position: center center;
}
@media screen and (max-width: 600px) {
.column {
width: 100%;
}
.content {
flex-direction: column;
}
}<div class="background-color">
<h2 id="projets">Mes Projets</h2>
<div class="row">
<div class="column">
<div class="content">
<img class="img" src="/assets/img/projectImage/pain.jpg" alt="Bred" style="width: 100%;">
<h3>My Work</h3>
<p>Lorem ipsum..</p>
</div>
</div>
<div class="column">
<div class="content">
<img class="img" src="/assets/img/projectImage/catmash.jpg" alt="catmash" style="width: 100%;">
<h3>My Work</h3>
<p>Lorem ipsum..</p>
</div>
</div>
<div class="column">
<div class="content">
<img class="img" src="/assets/img/projectImage/snakgame.jpg" alt="snakegame" style="width: 100%;">
<h3>My Work</h3>
<p>Lorem ipsum..</p>
</div>
</div>
</div>
</div>在没有display: flex的.content中添加flex-direction: column。相反，您需要添加.row，它包装了所有三个内容
@media screen and (max-width: 600px) {
.column {
width: 100%;
}
.content {
flex-direction: column;
}
}
看看这个：

</html>通过将width和height设置为相同的值，可以实现所有图像的相同大小。我通常只是在Photoshop等图像编辑软件中调整所有图像的大小，然后导入它们。保存在CSS中调整大小的工作。
