In a bootstrap responsive page how to center a div

Question

I need to create a responsive page using bootstrap by positio

Answer 1

Update for Bootstrap 4

Now that Bootstrap 4 is flexbox, vertical alignment is easier. Given a full height flexbox div, just us my-auto for even top and bottom margins...

<div class="container h-100 d-flex justify-content-center">
    <div class="jumbotron my-auto">
      <h1 class="display-3">Hello, world!</h1>
    </div>
</div>

Not the best way ,but will still work

<div class="container-fluid h-100">
<div class="row h-100">

<div class="col-lg-12">
<div class="row h-100">
  <div class="col-lg-4"></div>
  <div class="col-lg-4 border">
    This div is in middle

  <div class="col-lg-4"></div>
</div>

</div>
<div class="col-lg-12"></div>
</div>

</div>

jsFiddle

HTML:

<div class="container" id="parent">
  <div class="row">
    <div class="col-lg-12">text
      <div class="row ">
        <div class="col-md-4 col-md-offset-4" id="child">TEXT</div>
      </div>
    </div>
  </div>
</div>

CSS:

#parent {    
    text-align: center;
}
#child {
    margin: 0 auto;
    display: inline-block;
    background: red;
    color: white;
}

Good answer ppollono. I was just playing around and I got a slightly better solution. The CSS would remain the same, i.e. :

html, body, .container {
    height: 100%;
}
.container {
    display: table;
    vertical-align: middle;
}
.vertical-center-row {
    display: table-cell;
    vertical-align: middle;
}

But for HTML:

<div class="container">
    <div class="vertical-center-row">
        <div align="center">TEXT</div>
    </div>
</div>

This would be enough.

Answer 5

I think the simplest way to accomplish the layout with bootstrap is like this:

<section>
<div class="container">
    <div class="row">
        <div align="center">
            <div style="max-width: 200px; background-color: blueviolet;">
                <div>
                    <h1 style="color: white;">Content goes here</h1>
                </div>
            </div>
        </div>
    </div>
</div>

all I did was to add layers of divs that allowed me to center the div, but since I am not using percentages, you need to specify the max-width of the div to be center.

You can use this same method to center more than one column, you just need to add more div layers:

<div class="container">
    <div class="row">
        <div align="center">
            <div style="max-width: 400px; background-color: blueviolet;">
                <div class="col-md-12 col-sm-12 col-xs-12" style="background-color: blueviolet;">
                    <div class="col-md-8 col-sm-8 col-xs-12" style="background-color: darkcyan;">
                        <h1 style="color: white;">Some content</h1>
                    </div>
                    <div class="col-md-4 col-sm-4 col-xs-12" style="background-color: blue;">
                        <p style="color: white;">More content</p>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>

Note: that I added a div with column 12 for md, sm and xs, if you don't do this the first div with background color (in this case "blueviolet") will collapse, you will be able to see the child divs, but not the background color.

For actual version of Bootstrap 4.3.1 use

Style

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
<style type="text/css">
html, body {
    height: 100%;
}
</style>

Code

<div class="h-100 d-flex justify-content-center">
<div class="jumbotron my-auto">
<!-- example content -->
<div class="alert alert-success" role="alert">
<h4 class="alert-heading">Title</h4>
<p>Desc</p>
</div>
<!-- ./example content -->
</div>
</div
