问题描述
我有一个水平滚动元素(带有 overflow-x:scroll
),其中包含包含flex项目的flex容器.我正在尝试将背景应用于flex容器.
I have a horizontally scrolling element (with overflow-x:scroll
) with flex containers that contain flex items. I'm trying to apply background to the flex containers.
但是,如您在下面的示例中看到的(尝试向左/向右滚动),背景仅应用于视口的可见部分(橙色).有什么方法可以将其扩展为全宽,而不必为每个 .item
着色?
But as you can see in example below (try scrolling left/right) the background is applied only to visible part of viewport (orange). Is there some way to expand it to full width without having to color each .item
?
.list-container {
width: 100%;
display: flex;
flex-direction: row;
flex-wrap: nowrap;
background: tomato;
margin-bottom: 10px;
}
.item {
flex: 0 0 100px;
height: 100px;
margin-right: 10px;
background-color: skyblue;
opacity: 0.6;
}
.crop-container {
width: 300px;
overflow-x: scroll;
}
.item:first-child {
margin-left: 10px;
}
.item:last-child {
margin-right: 10px;
}
<div class='crop-container'>
<div class='list-container'>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
</div>
<div class='list-container'>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
</div>
</div>
推荐答案
以下是带有注释的更新代码:
Here is the updated code with comments:
.list-container {
/* width:100% Removed to allow element to expand */
display: inline-flex; /* inline to fit content width */
/*flex-direction: row;
flex-wrap: nowrap; Not needed since it the default behavior */
background: tomato;
margin-bottom: 10px;
}
.item {
width: 100px; /* Width instead of flex-basis */
flex-shrink:0; /* Avoid the shrinking*/
height: 100px;
margin-right: 10px;
background-color: skyblue;
opacity: 0.6;
}
.crop-container {
width: 300px;
overflow-x: scroll;
display: flex;
flex-direction: column;
align-items:flex-start; /* Change default alignement to avoid the stretch effect*/
}
.item:first-child {
margin-left: 10px;
}
/*.item:last-child {
margin-right: 10px;
} Not needed since all the elements already have margin-right */
<div class='crop-container'>
<div class='list-container'>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
</div>
<div class='list-container'>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
<div class='item'></div>
</div>
</div>
