In Bootstrap 3,How to change the distance between rows in vertical? - html

Question

I have two rows a and b,I think the distance between the two rows in vertical is too small.
I want to make the distance more bigger,I know I can change the distance in horizontal by col-md-offset-*.But how to change the vertical distance?
<div class="row" id="a">
<img> ... </img>
<div>
<div class="row" id="b">
<button>..</button>
<div>
Now my solution is insert a tag of h1,I think it is not graceful.
<div class="row" id="a">
<img> ... </img>
<div>
<h1></h1>
<div class="row" id="b">
<button>..</button>
<div>
Does it have more graceful solution?

Answer 1

Instead of adding any tag which is never a good solution. You can always use margin property with the required element.
You can add the margin on row class itself. So it will affect globally.
.row{
margin-top: 30px;
margin-bottom: 30px
}
Update: Better solution in all cases would be to introduce a new class and then use it along with .row class.
.row-m-t{
margin-top : 20px
}
Then use it wherever you want
<div class="row row-m-t"></div>

Answer 2

use:
<div class="row form-group"></div>

Answer 3

If it was me I would introduce new CSS class and use along with unmodified bootstrap row class.
HTML
<div class="row extra-bottom-padding" id="a">
<img>...</img>
<div>
<div class="row" id="b">
<button>..</button>
<div>
CSS
.row.extra-bottom-padding{
margin-bottom: 20px;
}

UPDATE
Bootstrap 4 has spacing utilities to handle this https://getbootstrap.com/docs/4.0/utilities/spacing/
.mt-0 {
margin-top: 0 !important;
}

ORIGINAL ANSWER
If you are using SASS, this is what I normally do.
$margins: (xs: 0.5rem, sm: 1rem, md: 1.5rem, lg: 2rem, xl: 2.5rem);
#each $name, $value in $margins {
.margin-top-#{$name} {
margin-top: $value;
}
.margin-bottom-#{$name} {
margin-bottom: $value;
}
}
so you can later use margin-top-xs for example

Answer 5

Use <br> tags
<div class="container">
<div class="row" id="a">
<img src="http://placehold.it/300">
</div>
<br><br> <!--insert one, two, or more here-->
<div class="row" id="b">
<button>Hello</button>
</div>
</div>

Answer 6

There's a simply way of doing it.
You define for all the rows, except the first one, the following class with properties:
.not-first-row
{
position: relative;
top: -20px;
}
Then you apply the class to all non-first rows and adjust the negative top value to fit your desired row space. It's easy and works way better. :)
Hope it helped.
