Can I give the col-md-1.5 in bootstrap?

Html Problem Overview

I want to adjust the columns in Twitter Boοtstrap.

I know in bootstrap there are 12 columns grid. Is there any way to manipulate the grids to have 1.5 3.5 3.5 3.5 instead of 3 3 3 3?

You cloud also simply override the width of the Column...

<div class="col-md-1" style="width: 12.499999995%"></div>

Since col-md-1 is of width 8.33333333%; simply multiply 8.33333333 * 1.5 and set it as your width.

in bootstrap 4, you will have to override flex and max-width property too:

<div class="col-md-1" style="width: 12.499999995%;
    flex: 0 0 12.499%;max-width: 12.499%;"></div>

As @bodi0 correctly said, it is not possible. You either have to extent Bootstrap's grid system (you can search and find various solutions, here is a 7-column example) or use nested rows e.g. http://bootply.com/dd50he9tGe.

In the case of nested rows you might not always get the exact result but a similar one

<div class="row">
    <div class="col-lg-5">
        <div class="row">
            <div class="col-lg-4">1.67 (close to 1.5)</div>
            <div class="col-lg-8">3.33 (close to 3.5)</div>
        </div>    
    </div>
    <div class="col-lg-7">
        <div class="row">
            <div class="col-lg-6">3.5</div>
            <div class="col-lg-6">3.5</div>
        </div>    
    </div>
</div>

The short answer is no (technically you can give whatever name of the class you want, but this will have no effect, unless you define your own CSS class - and remember - no dots in the class selector). The long answer is again no, because Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or view port size increases.

Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.

Use rows to create horizontal groups of columns.
Content should be placed within columns, and only columns may be immediate children of rows.
Predefined grid classes like .row and .col-xs-4 are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
Columns create gutters (gaps between column content) via padding. That padding is offset in rows for the first and last column via negative margin on .rows.
Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .col-xs-4.
If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.
Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, e.g. applying any .col-md-* class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg-* class is not present.

A possible solution to your problem is to define your own CSS class with desired width, let's say .col-half{width:XXXem !important} then add this class to elements you want along with original Bootstrap CSS classes.

Bootstrap 4 uses flex-box and you can create your own column definitions

This is close to a 1.5, tweak to your own needs.

.col-1-5 {
    flex: 0 0 12.3%;
    max-width: 12.3%;
    position: relative;
    width: 100%;
    padding-right: 15px;
    padding-left: 15px;
}

Solution 5 - Html

I have created a custom bootstrap extension that allows you to use the following classes:

// replace * with a number between 0 and 11
col-*-1qtr
col-*-half
col-*-3qtr

Also note that you can use responsive classes, such as:

col-sm-2-half (2.5)
col-md-0-3qtr (0.75)
col-lg-11-1qtr (11.25)
col-xl-5-half (5.5)

Here is an example:

<!DOCTYPE html>
<html lang="en">
<head>
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
  <link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/hoomanbahreini/bootstrap-half-and-quarter-grid/fractional-grid.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.16.0/umd/popper.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
  <h2>Using fraction of columns</h2>
  <div class="row">
    <div class="col-2-3qtr bg-success">col-2-3qtr (2.75)</div>
    <div class="col-3-1qtr bg-warning">col-3-1qtr (3.25)</div>
    <div class="col-3-half bg-success">col-3-half (3.5)</div>
    <div class="col-2-half bg-warning">col-2-half (2.5)</div>
  </div>
</div>

</body>
</html>

Bootstrap has column offsets, so if you want columns with equal width without specifying size use this.

<div class="row">
  <div class="col">col</div>
  <div class="col">col</div>
  <div class="col">col</div>
  <div class="col">col</div>
</div>

Solution 7 - Html

Create new classes to overwrite the width. See jFiddle for working code.

<div class="row">
  <div class="col-xs-1 col-xs-1-5">
    <div class="box">
      box 1
    </div>
  </div>
  <div class="col-xs-3 col-xs-3-5">
    <div class="box">
      box 2
    </div>
  </div>
  <div class="col-xs-3 col-xs-3-5">
    <div class="box">
      box 3
    </div>
  </div>
  <div class="col-xs-3 col-xs-3-5">
    <div class="box">
      box 4
    </div>
  </div>
</div>

.col-xs-1-5 {
  width: 12.49995%;
}
.col-xs-3-5 {
  width: 29.16655%;
}
.box {
  border: 1px solid #000;
  text-align: center;
}

According to Rex Bloom response I have write a bootstrap helper:

//8,33333333% col-1

.extra-col {
  position: relative;
  width: 100%;
  padding-right: 15px;
  padding-left: 15px;
}

.col-0-5 {
  @extend .extra-col;
  flex: 0 0 4.16666667%;
  max-width: 4.16666667%;
}

.col-1-5 {
  @extend .extra-col;
  flex: 0 0 12.5%;
  max-width: 12.5%;
}

.col-2-5 {
  @extend .extra-col;
  flex: 0 0 20.833333325%;
  max-width: 20.833333325%;
}

.col-3-5 {
  @extend .extra-col;
  flex: 0 0 29.166666655%;
  max-width: 29.166666655%;
}

.col-4-5 {
  @extend .extra-col;
  flex: 0 0 37.499999985%;
  max-width: 37.499999985%;
}

.col-5-5 {
  @extend .extra-col;
  flex: 0 0 45.833333315%;
  max-width: 45.833333315%;
}

.col-6-5 {
  @extend .extra-col;
  flex: 0 0 54.166666645%;
  max-width: 54.166666645%;
}

.col-7-5 {
  @extend .extra-col;
  flex: 0 0 62.499999975%;
  max-width: 62.499999975%;
}

.col-8-5 {
  @extend .extra-col;
  flex: 0 0 70.833333305%;
  max-width: 70.833333305%;
}

.col-9-5 {
  @extend .extra-col;
  flex: 0 0 79.166666635%;
  max-width: 79.166666635%;
}

.col-10-5 {
  @extend .extra-col;
  flex: 0 0 87.499999965%;
  max-width: 87.499999965%;
}

.col-11-5 {
  @extend .extra-col;
  flex: 0 0 95.8333333%;
  max-width: 95.8333333%;
}

Solution 9 - Html

This is not Bootstrap Standard to give col-md-1.5 and you can not edit bootstrap.min.css because is not right way. you can create like this http://www.bootply.com/125259

Solution 10 - Html

As others mentioned in Bootstrap 3, you can use nest/embed techniques.

However it is becoming more obvious to use pretty awesome feature from Bootstrap 4 now. you simple have the option to use the col-{breakpoint}-auto classes (e.g. col-md-auto) to make columns size itself automatically based on the natural width of its content. check this for example

Solution 11 - Html

you can use this code inside col-md-3 , col-md-9

.col-side-right{
  flex: 0 0 20% !important;
  max-width: 20%;
}

.col-side-left{
  flex: 0 0 80%;
  max-width: 80%;
}

Solution 12 - Html

This question is quite old, but I have made it that way (in TYPO3).

Firstly, I have made a own accessible css-class which I can choose on every content element manually.

Then, I have made a outer three column element with 11 columns (1 - 9 - 1), finally, I have modified the column width of the first and third column with CSS to 12.499999995%.
