I am trying to use the bootstrap 4 grid system to center a single column. In bootstrap 3 I was able to do:
<div class="col-md-10 col-md-offset-2">
</div>
In bootstrap 4 the same does not work even when using the new offset class: offset-md-2.
The following works, but something feels wrong about having empty columns on the page, just to center a col-md-5.
<div class="row">
<div class="col"></div>
<div class="col-md-5 align-self-center">
<img src="img/myimage.gif" style="width: 100%;">
</div>
<div class="col"></div>
</div>
The first approach uses bootstrap offset class. The key is to set an offset equal to half of the remaining size of the row. So for example, a column of size 2 would be centered by adding an offset of 5, that's (12-2)/2.
1 — Vertical Center Using Auto Margins One way to vertically center is to use my-auto . This will center the element within it's flexbox container (The Bootstrap 4 . row is display:flex ). For example, h-100 makes the row full height, and my-auto will vertically center the col-sm-12 column.
To center the items within a column, we use align-items and justify-items instead of the align-content and justify-content in our previous example. Using the item properties, we can align our items just like we did with our columns.
Column content --> </div> </div> </div> But, in Bootstrap 3 things are little different. If the grid column number is even (e.g., 2, 4, 6, 8, 10, 12) you can use the class .col- {xs|sm|md|lg}-offset-* to align the column in center, like this:
Bootstrap 4 Grid System. Bootstrap's grid system allows up to 12 columns across the page. If you do not want to use all 12 column individually, you can group the columns together to create wider columns:
How to Center a Column in Bootstrap. Topic: Bootstrap / Sass Prev|Next. Answer: Use the mx-auto Class. If you are using the Bootstrap 4 version, you can horizontally center a grid column by applying the class .mx-auto on it. Let's try out the following example to see how it works:
You can also use the .justify-content-between to place the first column to the left side at the start and the second column to the right side at the end. The columns in a row work according to the 12 grid columns. When the column size increases the 12 column grid, it goes down to the next row in Bootstrap.
As per the documentation you can use justify-content-center on the row to center any number of columns in a row.
<div class="row justify-content-center">
<div class="col-4">
One centered column
</div>
</div>
