我在堆栈溢出中找到了以下代码。
但是,该代码不会使图像居中。有人可以帮我吗?
HTML:
<div class="photo">
<a href="#">
<img src="https://www.weebly.com/editor/uploads/2/9/9/6/29968995/custom_themes/185017182709687634/files/img/beforeafter/s6.jpg" alt="before" class="before">
<img src="https://www.weebly.com/editor/uploads/2/9/9/6/29968995/custom_themes/185017182709687634/files/img/beforeafter/s1.jpg" alt="after" class="after">
</a>
</div>
CSS:
img {
width: 300px;
}
.photo {
position: relative;
overflow-x: hidden;
}
.photo .after {
position: absolute;
top: 0;
left: 0;
display: none;
}
.photo .before:hover + .after, .after:hover {
display: block;
}
答案 0 :(得分:0)
有多种方法可以最简单地实现Flex布局,您需要编辑photo类的CSS,并添加以下代码行:
.photo {
display: flex;
justify-content: center; //horizontal align to center
/* align-items: center*/ --> this will align it vertically.
}
flex的默认方向是行(水平),属性的行为也相应。如果我们更改flex-direction: column
,justify-content
和align-items
的行为取决于方向。
