我有类似的东西:
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<div class="container">
<div class="row">
<div class="col-sm-6">
<div class="btn-group">
<button type="button" class="btn btn-default">Button 1</button>
<button type="button" class="btn btn-default">Button 2</button>
<button type="button" class="btn btn-default">Button 3</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-default">Button 4</button>
<button type="button" class="btn btn-default">Button 5</button>
<button type="button" class="btn btn-default">Button 6</button>
</div>
<div class="btn-group">
<button type="button" class="btn btn-default">Button 7</button>
<button type="button" class="btn btn-default">Button 8</button>
<button type="button" class="btn btn-default">Button 9</button>
</div>
</div>
<div class="col-sm-6">
</div>
</div>
</div>
&#13;
我想要按钮矩阵3x3。还有一件事,左侧和右侧必须看起来像这个例子(直线):
<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<div class="container">
<div class="btn-group-vertical">
<button type="button" class="btn btn-default">button</button>
<button type="button" class="btn btn-default">button</button>
<button type="button" class="btn btn-default">button</button>
</div>
</div>
&#13;
我怎么做到的?也许我需要添加一些引导类或编辑css文件?
答案 0 :(得分:13)
仅使用.btn-group
类的一个块。
使用伪类应用一组CSS属性:
clear: left;
属性强制按钮开始矩阵的新行。这是因为.btn
类具有float: left;
属性。
设置border-radius
和margin
属性的方式与bootstrap.css文件中描述的btn-group
类相似。
请检查结果:
@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css');
/* The heart of the matter */
.btn-matrix > .btn:nth-child(3n+4) {
clear: left;
margin-left: 0;
}
.btn-matrix > .btn:nth-child(n+4) {
margin-top: -1px;
}
.btn-matrix > .btn:first-child {
border-bottom-left-radius: 0;
}
.btn-matrix > .btn:nth-child(3) {
border-top-right-radius: 4px !important;
}
.btn-matrix > .btn:nth-last-child(3) {
border-bottom-left-radius: 4px !important;
}
.btn-matrix > .btn:last-child {
border-top-right-radius: 0;
}
/* Decorations */
.btn-matrix {
margin: 20px;
}
<div class="btn-group btn-matrix">
<button type="button" class="btn btn-default">Button 1</button>
<button type="button" class="btn btn-default">Button 2</button>
<button type="button" class="btn btn-default">Button 3</button>
<button type="button" class="btn btn-default">Button 4</button>
<button type="button" class="btn btn-default">Button 5</button>
<button type="button" class="btn btn-default">Button 6</button>
<button type="button" class="btn btn-default">Button 7</button>
<button type="button" class="btn btn-default">Button 8</button>
<button type="button" class="btn btn-default">Button 9</button>
</div>
代码仅取决于X:
.btn-matrix > .btn:nth-child(Xn+X+1) {
clear: left;
margin-left: 0;
}
.btn-matrix > .btn:nth-child(n+X+1) {
margin-top: -1px;
}
.btn-matrix > .btn:first-child {
border-bottom-left-radius: 0;
}
.btn-matrix > .btn:nth-child(X) {
border-top-right-radius: 4px !important;
}
.btn-matrix > .btn:nth-last-child(X) {
border-bottom-left-radius: 4px !important;
}
.btn-matrix > .btn:last-child {
border-top-right-radius: 0;
}

您可以尝试以下操作:
<div class="row">
<div class="col-md-1 btn-group">
<button type="button" class="btn btn-default">Button 1</button>

修改后的@Pranjal因为以下原因而回答:
因此,我们为3行按钮的每一行创建一个带有类行的div。此外,我们希望按钮为行宽(12列)的1/3,因此我们给它类&#34; col-md-4&#34; (12除以3)。

我认为这会对你有所帮助。试试这个。
while (1 == scanf("%s", s))
{
// Parse the string s and add value to array
}
button{
margin-right:14px!important;
}

对于Bootstrap 4,如果您需要包装的文字不等。
.btn-matrix > .btn:nth-child(3n+4) {
clear: left;
margin-left: 0;
}
.btn-matrix > .btn:nth-child(n+4) {
margin-top: -1px;
}
.btn-matrix > .btn:first-child {
border-bottom-left-radius: 0;
}
.btn-matrix > .btn:nth-child(3) {
border-top-right-radius: 4px !important;
}
.btn-matrix > .btn:nth-last-child(3) {
border-bottom-left-radius: 4px !important;
}
.btn-matrix > .btn:last-child {
border-top-right-radius: 0;
}
/* Decorations */
.btn-matrix { flex-wrap: wrap; }
/* force wrap text */
.btn-matrix .btn{
white-space: normal !important;
}
<div class="btn-group btn-matrix">
<a class="btn btn-sm btn-default col-sm-4">Button 1 Extra Content</a>
