How can I modify CSS styles in AngularJS with Bootstrap UI?

Utilizing bootstrap UI in conjunction with AngularJS directives, I am looking to customize the default styles that bootstrap applies to its elements.

Is it recommended to target the HTML contents within the template?

Referring to the examples provided in the documentation, my intention is to incorporate the accordion.

Upon defining it in HTML, the structure appears as follows:

<accordion>
    <accordion-group heading="my heading">
      content here
    </accordion-group>

However, upon processing the directive template, the HTML transformations are notable:

<accordion close-others="oneAtATime"><div class="panel-group" ng-transclude="">
    <div class="panel panel-default ng-isolate-scope" heading="my heading">
        <div class="panel-heading">
            <h4 class="panel-title">
                <a class="accordion-toggle" ng-click="toggleOpen()" accordion-transclude="heading">
                    <span ng-class="{'text-muted': isDisabled}" class="ng-binding">content here</span>
                </a>
            </h4>
        </div>
        <div class="panel-collapse collapse" collapse="!isOpen" style="height: 0px;">
        <div class="panel-body" ng-transclude=""><span class="ng-scope">some content here</span></div>
    </div>

The transformation is quite significant. If I aim to alter the appearance of the panel title, should I define this in my CSS files?

div.panel {}

and hope that the template remains static in the future?

What would be the most effective approach to modifying styles for HTML elements generated by a directive's templates?

Answer №1

To customize the appearance of your website, it is recommended to include your site-specific CSS (site-specific.css) after Bootstrap's default CSS file (bootstrap.css). This way, you can easily override existing rules by redefining them.

For instance, if you are embedding CSS within your <head> section like this:

<link rel="stylesheet" href="css/bootstrap.css" />
<link rel="stylesheet" href="css/site-specific.css" />

You can then proceed to modify the panel styles in your site-specific.css file:

.panel {
    //your custom code here
}

This method allows you to make changes without worrying about future template updates affecting your design. Since you are using a specific version, any updates made by Bootstrap will not impact your customized template with its unique version name.
