我使用flexbox作为网格列
在第一行中,我有三个dr-col-1
和两个dr-col-2
(共有flex-grow
个步骤。)
在第二行,我有七个dr-col-1
。
当我渲染它时,我注意到它的对齐不精确:
如何精确对齐两行中的列?
.dr-row {
display: flex;
}
.dr-col-1 {
flex-grow: 1;
flex-basis: 0;
border: 1px solid black;
}
.dr-col-2 {
flex-grow: 2;
flex-basis: 0;
border: 1px solid black;
}

<div class="dr-row">
<div class="dr-col-2">
one
</div>
<div class="dr-col-1">
two
</div>
<div class="dr-col-1">
three
</div>
<div class="dr-col-1">

</div>
<div class="dr-col-2">

</div>
<div class="dr-row">

<div class="dr-col-1">

<div class="dr-col-1">

答案 0 :(得分:2)
当你有两个.dr-col-1
时,有4个边框,4 * 1px = 4px。
当你有一个.dr-col-2
时,有2个边框,2 * 1px = 2px。
所以你需要补偿2px的差异,例如通过增加flex-basis
:
.dr-col-2 {
flex-basis: 2px; /* flexFactor * borderWidth */
}
.dr-row {
display: flex;
}
.dr-col-1 {
flex-grow: 1;
flex-basis: 0;
border: 1px solid black;
}
.dr-col-2 {
flex-grow: 2;
flex-basis: 2px;
border: 1px solid black;
}
&#13;
<div class="dr-row">
<div class="dr-col-2">one</div>
<div class="dr-col-1">two</div>
<div class="dr-col-1">three</div>
<div class="dr-col-1">four</div>
<div class="dr-col-2">five</div>
</div>
<div class="dr-row">
<div class="dr-col-1">one</div>
<div class="dr-col-1">two</div>
<div class="dr-col-1">three</div>
<div class="dr-col-1">four</div>
<div class="dr-col-1">five</div>
<div class="dr-col-1">six</div>
<div class="dr-col-1">seven</div>
</div>

答案 1 :(得分:1)
flex-grow
属性旨在分配容器中的可用空间。它不适用于灵活项目的特定大小(flex-basis
)。
列没有对齐,因为第二行中有更多垂直边框。
更具体地说,第一行有8px的边框宽度,第二行有12px的边框宽度(不包括边缘)。
这意味着第一行中有更多的可用空间,这会导致错位。
而不是使用flex-grow
尝试使用flex-basis
:
.dr-row {
display: flex;
}
.dr-col-1 {
flex: 0 0 14.29%;
border: 1px solid black;
box-sizing: border-box;
}
.dr-col-2 {
flex: 0 0 28.58%;
border: 1px solid black;
box-sizing: border-box;
}
body { margin: 0; }
&#13;
<div class="dr-row">
<div class="dr-col-2">one</div>
<div class="dr-col-1">two</div>
<div class="dr-col-1">three</div>
<div class="dr-col-1">four</div>
<div class="dr-col-2">five</div>
</div>
<div class="dr-row">
<div class="dr-col-1">one</div>
<div class="dr-col-1">two</div>
<div class="dr-col-1">three</div>
<div class="dr-col-1">four</div>
<div class="dr-col-1">five</div>
<div class="dr-col-1">six</div>
<div class="dr-col-1">seven</div>
</div>

边界也需要一些地方
这里是相同的HTML / CSS,但我使用的是轮廓而不是边框。
https://jsfiddle.net/nfo1pg9f/
.dr-row {
display: flex;
box-sizing: border-box;
}
.dr-col-1 {
flex-grow: 1;
flex-basis: 0;
outline: 1px solid black;
}
.dr-col-2 {
flex-grow: 2;
flex-basis: 0;
outline: 1px solid black;
}
<div class="dr-row">
<div class="dr-col-2">

</div>
<div class="dr-col-1">

<div class="dr-col-1">

<div class="dr-col-1">

这里尝试一下,不确定它是否是最佳解决方案,但无论浏览器大小如何,它似乎都完美对齐
边框似乎在元素上关闭,向grow增加一个像素:2;似乎再次重新调整事物。我为外观目的添加了一些边距和填充
.dr-row {
display: flex;
flex-flow: row wrap;
justify-content: space-around;
}
.dr-row div{
margin:5px;
flex-basis: 0;
border: 1px solid black;
}
.dr-col-1 {
flex-grow: 1;
}
.dr-col-2 {
flex-grow: 2;
padding: 6px;
}
