CSS - completely remove spacing between columns? - html

Question

I have this HTML:
<div class="container">
<div class="box center-block">
<div class="row">
<div class="col-md-4 col-xs-4">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4">
<div class="thumbnail">A</div>
</div>
</div>
<div class="row">
<div class="col-md-4 col-xs-4">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4">
<div class="thumbnail">A</div>
</div>
</div>
<div class="row">
<div class="col-md-4 col-xs-4">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4">
<div class="thumbnail">A</div>
</div>
</div>
</div>
</div>
And CSS:
.box {
width: 300px;
padding-top: 100px;
}
.row > div > div {
width: 100px;
height: 100px;
margin: 0px;
}
I'm also using bootsrap (version 3).
I was able to remove margin between rows, but can't remove margin between columns. Is there a way to force it somehow?
I need all "squares" next to each other without any margins (both between rows and columns).

Answer 1

If you really want to use col- class, make sure to set the .thumbnail elements width to 100% and use a no-padding class on the col- elements.
Here is an example:
#import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css');
.box {
width: 300px;
padding-top: 100px;
}
.no-padding {
padding-left: 0;
padding-right: 0;
}
.thumbnail {
width: 100%;
height: 100px;
margin: 0;
}
<div class="container">
<div class="box center-block">
<div class="row">
<div class="col-md-4 col-xs-4 no-padding">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 no-padding">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 no-padding">
<div class="thumbnail">A</div>
</div>
</div>
<div class="row">
<div class="col-md-4 col-xs-4 no-padding">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 no-padding">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 no-padding">
<div class="thumbnail">A</div>
</div>
</div>
<div class="row">
<div class="col-md-4 col-xs-4 no-padding">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 no-padding">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 no-padding">
<div class="thumbnail">A</div>
</div>
</div>
</div>
</div>
You actually do not need to use col- classes at all and floats are not needed either. Another way to do this is using display: inline-block.
Here is how that looks:
#import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css');
.wrapper {
width: 300px;
padding-top: 100px;
margin: 0 auto;
font-size: 0;
}
.item {
border: 1px solid #eee;
width: 100px;
height: 100px;
display: inline-block;
font-size: initial;
}
<div class="wrapper">
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
</div>
And if you're really brave you could also use CSS Grid layout. ;)
CSS Grid Layout
CSS Grid layout excels at dividing a page into major regions, or defining the relationship in terms of size, position, and layer, between parts of a control built from HTML primitives.
Here is how that goes:
.wrapper {
padding-top: 100px;
width: 300px;
margin: 0 auto;
display: grid;
grid-template-columns: repeat(3,100px);
grid-template-rows: repeat(3,100px);
}
.item {
border: 1px solid #ddd;
height: 100px;
width: 100px;
}
<div class="wrapper">
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
<div class="item">A</div>
</div>

Answer 2

It's because .col-*-4 is wider than 100px, which is the width you've defined for the .thumbnail elements.
You can just remove the .col-* classes and use .pull-left instead.
.box {
width: 300px;
padding-top: 100px;
}
.row > div > div {
width: 100px;
height: 100px;
margin: 0;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container">
<div class="box center-block">
<div class="row">
<div class="pull-left">
<div class="thumbnail">A</div>
</div>
<div class="pull-left">
<div class="thumbnail">A</div>
</div>
<div class="pull-left">
<div class="thumbnail">A</div>
</div>
</div>
<div class="row">
<div class="pull-left">
<div class="thumbnail">A</div>
</div>
<div class="pull-left">
<div class="thumbnail">A</div>
</div>
<div class="pull-left">
<div class="thumbnail">A</div>
</div>
</div>
<div class="row">
<div class="pull-left">
<div class="thumbnail">A</div>
</div>
<div class="pull-left">
<div class="thumbnail">A</div>
</div>
<div class="pull-left">
<div class="thumbnail">A</div>
</div>
</div>
</div>
</div>

Answer 3

Remove padding-left and padding-right for .col classes and then change width: 100px; to width: 100%; for .row > div > div
.box {
width: 300px;
padding-top: 100px;
}
.padding-0{
padding-right:0 !important;
padding-left:0 !important;
}
.row > div > div {
width: 100%;
height: 100px;
margin: 0px;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container">
<div class="box center-block">
<div class="row">
<div class="col-md-4 col-xs-4 padding-0">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 padding-0">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 padding-0">
<div class="thumbnail">A</div>
</div>
</div>
<div class="row">
<div class="col-md-4 col-xs-4 padding-0">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 padding-0">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 padding-0">
<div class="thumbnail">A</div>
</div>
</div>
<div class="row">
<div class="col-md-4 col-xs-4 padding-0">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 padding-0">
<div class="thumbnail">A</div>
</div>
<div class="col-md-4 col-xs-4 padding-0">
<div class="thumbnail">A</div>
</div>
</div>
</div>
</div>

Answer 4

Row has it's own style and add margin to element, you can remove it by adding :
.box >.row{
margin:0;
}
