Is it possible to customize bootstrap classes for a unique bootstrap css design?

In my MVC4 project, I faced a situation where I had a global.css class with some classes that conflicted with Bootstrap after adding it. To resolve this, I created a new file called bootstrap_migration.css. In this file, I prefixed the Bootstrap classes with .bt, so in my HTML, I used classes like class="bt container", which worked perfectly.

For example, in my bootstrap_migration.css:

.bt .jumbotron {
  padding: 30px;
  margin-bottom: 30px;
  font-size: 21px;
  font-weight: 200;
  line-height: 2.1428571435;
  color: inherit;
  background-color: #eeeeee;
}

Is there a more efficient way to handle this issue?

Answer №1

It is important to avoid leaving spaces in class names when writing HTML code. Instead of using ".bt .jumbotron", it should be written as:

.bt.jumbotron

Remember, when you use a space between classes like ".bt .jumbotron", it means that "jumbotron" is a child of "bt". This will not apply the styles to the same element.

Answer №2

.bt.jumbotron

Avoid including spaces between the classes.

Adding spaces between classes implies that it is a descendant of another.

To customize your Bootstrap styles without modifying the original bootstrap.css file, you can add a new CSS file named "bootstrap-custom.css" and include it after your bootstrap.css in the HTML header.

For example:

<link rel="stylesheet" type="text/css" media="screen" href="/css/bootstrap.min.css" />
<link rel="stylesheet" type="text/css" media="screen" href="/css/bootrstrap-custom.css" />

You can then override any Bootstrap classes by copying the element definition into your custom file and adjusting the attributes there. Tools like Firebug can be helpful for identifying which elements to modify.

For instance, if your bootstrap.css contains:

.jumbotron {
  padding: 30px;
  margin-bottom: 30px;
  font-size: 21px;
  font-weight: 200;
  line-height: 2.1428571435;
  color: inherit;
  background-color: #eeeeee;
}

If you only want to change the padding, you can add the following to your bootstrap-custom.css:

.jumbotron {
    padding: 20px; /* For example */
}

By following this method, you can make modifications without altering the original bootstrap.css file.

To enhance the customization of the bootstrap file, consider utilizing the source bootstrap via LESS (available for download here, by using the Download source code link)

With the use of LESS, you can nest classes to easily apply changes across multiple affected classes and make additional customizations effortlessly.

By adding the Web Essentials extension to your Visual Studio, this file will be automatically updated as you make edits.

Your current approach is already optimized; there's no better way to handle the rest of the solution.
