问题:

I have something like that:

<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>

And I would like to have matrix of buttons 3x3. One more thing, left and right side must look like this example (straight lines):

<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>

How I can make it? Maybe I need to add some bootstrap class or edit css file?

回答1:

One group of buttons + few pseudo-classes

  1. Use only one block with the .btn-group class.

  2. Apply a set of CSS properties by using of pseudo-classes:

    • :first-child
    • :last-child
    • :nth-child()
    • :nth-last-child()

  3. The clear: left; property forces the button to start a new row of the matrix. It's because the .btn class has the float: left; property.

  4. Set up border-radius and margin properties in a similar way as the btn-group class is described in the bootstrap.css file.

3×3 matrix

Please check the result:

@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>

X×Y matrix

The code depends only on 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;
}

You can try the following:

    <div class="row">
        <div class="col-md-1 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="col-md-1 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="col-md-1 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>

Modified @Pranjal answer a bit because of following reason:

  • the bootstrap grid (row, col-... etc) creates rows which are by definition 12 columns wide

Because of this we create a div with class row for each row of 3 buttons. Also, we want the buttons the be 1/3 of the width of the row (12 columns) so we give it the class "col-md-4" (12 divided by 3).

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>

<div class="container-fluid">            
  <div class="row">          
    <div class="btn-group">
      <button type="button" class="btn btn-default col-md-4">Button 1</button>
      <button type="button" class="btn btn-default col-md-4">Button 2</button>
      <button type="button" class="btn btn-default col-md-4">Button 3</button>
    </div>
  </div>
  <div class="row">
    <div class=" btn-group">
      <button type="button" class="btn btn-default col-md-4">Button 4</button>
      <button type="button" class="btn btn-default col-md-4">Button 5</button>
      <button type="button" class="btn btn-default col-md-4">Button 6</button>
    </div>
  </div>
  <div class="row">
    <div class=" btn-group">
      <button type="button" class="btn btn-default col-md-4">Button 7</button>
      <button type="button" class="btn btn-default col-md-4">Button 8</button>
      <button type="button" class="btn btn-default col-md-4">Button 9</button>
    </div>
  </div>
</div>

For Bootstrap 4 and if you have unequal text that needs to wrap.

.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>
  <a  class="btn btn-sm btn-default col-sm-4">Button 2</a>
  <a  class="btn btn-sm btn-default col-sm-4">Button 3</a>
  <a  class="btn btn-sm btn-default col-sm-4">Button 4</a>
  <a  class="btn btn-sm btn-default col-sm-4">Button 5</a>
  <a  class="btn btn-sm btn-default col-sm-4">Button 6</a>
  <a  class="btn btn-sm btn-default col-sm-4">Button 7</a>
  <a  class="btn btn-sm btn-default col-sm-4">Button 8</a>
  <a  class="btn btn-sm btn-default col-sm-4">Button 9</a>
</div>
