How to avoid bootstrap from overriding id-called custom css?

Tags: html,css,twitter-bootstrap

Problem :

I want a div in my code to be horizontally center aligned, but also need to use bootstrap col-md-12 class. So I used the following.

<div id="canvas" class="col-md-12">

And I declared css as:

#page-body #canvas {
    border: 2px solid black;
    margin: 50px auto;
    padding: 10px;
    width: 60%;

However, this is being overridden by bootstraps float attribute:

.col-md-1, .col-md-2, .col-md-3, .col-md-4, .col-md-5, .col-md-6, .col-md-7, .col-md-8, .col-md-9, .col-md-10, .col-md-11, .col-md-12 {
    float: left;

I don't wish to use the !important or change the bootstrap code.

When I was looking for solutions, I found that

  1. Calling by id is suitable, which I have done without luck.
  2. I tried this problem's solution using the specificity calculator which gave 200:10 results, but still not working.
  3. My custom css link is placed after the bootstrap link

Is there a clean way to avoid this override?

The desired output is got when the col-md-12 class is not used but I want to use the bootstrap class.

UPDATE : Basically using class container instead of col-md-12 gave out the desired output, but does it have any side effects? JSFIDDLE

Solution :

    <div class="container">
        <div class="col-md-6 col-md-offset-3 bg-danger">

This can be used as the answer for your requirement. Instead of using custom styles for making div centered horizontally you can use the offset style provided by bootstrap.

The class bg-danger is used for demonstration purpose only.
