Bootstrap change $grid-gutter-width

问题

I am using Bootstraps grid system and I need about a 2px space between each column. I've tried Column-Gap but nothing.

Could anyone help?

Code HTML:

<div class="container">
<div class="row">
<div class="col-md-3" id="one">
<h3>Pink</h3>

</div>
<div class="col-md-3" id="two">
<h3>Purple</h3>
</div>
<div class="col-md-3" id="three">
<h3>Green</h3>
</div>
<div class="col-md-3" id="four">
<h3>Orange</h3>
</div>
</div>
<div class="row2">
<div class="col-md-3" >
<h3>Things that are Pink</h3>
<p>Pigs</p>
<p>Barbie</p>
<p>Some Skins</p>
<p>Ham</p>
</div>
<div class="col-md-3" >
<h3>Things that are Purple</h3>
<p>Prince</p>
<p>Goths</p>
<p>Paint</p>
<p>Berries</p>
</div>
<div class="col-md-3" >
<h3>Things that are Green</h3>
<p>Grass</p>
<p>Peas</p>
<p>Leafs</p>
<p>Apple</p>
</div>
<div class="col-md-3" >
<h3>Things that are Orange</h3>
<p>Orange</p>
<p>Ice-Lolly</p>
<p>Essex</p>
<p>Carrots</p>
</div>
</div>
</div>
</body>
</html>

Code: CSS

body {
font-family: 'Roboto Mono', monospace;

}

@media screen and (min-width: 768px)
.jumbotron {
padding-top: 48px;
padding-bottom: 48px;
}

.jumbotron {
text-align: center;
}

.container {
text-align: center;
}

#one {
border: 5px solid pink;
border-radius: 20px;
background-color: pink;
color: white;
}

#two {
border: 5px solid purple;
border-radius: 20px;
background-color: purple;
color: white;
}

#three {
border: 5px solid green;
border-radius: 20px;
background-color: green;
color: white;
}

#four {
border: 5px solid orange;
border-radius: 20px;

}

.row2 {
margin-top: 30px;

回答1:

to change the gutter you have two way:

change @grid-gutter-width in variables.less:327, but then you will need to compile the generated css yourself.
change @grid-gutter-width and download a new custom build at Bootstrap#Customize

Note that the customize section will be dropped in twitter bootstrap 4.
