Why won't my Angular application properly set the background when there are two or more components within it?

I have developed an application that consists of 4 components within it:

<div [@routerTransition] class="position-relative overflow-hidden pt-3 m-md-3">
  <div class="mx-auto mb-5 pb-1 container">
    <app-set-vehicle-details id="step1" (step1Finished)="enableStep2($event)" (busy)="setBusy($event)"></app-set-vehicle-details>
    <app-product-selection id="step2" *ngIf="step2Enabled"></app-product-selection>
    <app-product-details id="step3" *ngIf="step3Enabled"></app-product-details>
    <app-customer-details id="step4" *ngIf="step4Enabled"></app-customer-details>
   </div>
 </div>

Initially, the view is intended to appear like this:

However, when the second component is introduced, the background color changes to white:

This sudden change in background color is perplexing. Here is a snippet of the CSS related to it:

.theme-main [_nghost-etm-c5] {
   background-color: #F0F0F7 !important;
   color: #4D4F5C !important;
}

A screenshot showcasing the main container can be seen here:

The appearance of the white space remains unexplained. The only notable event is the dynamic addition of the second component after an action is triggered. Could this cause the height discrepancy?

Your insights and assistance are greatly appreciated!

To provide further clarity:

  • Styling details are fetched from a custom library referenced as styles.scss

  • Here's the style associated with the body:

Applying Bootstrap's h-100 should ideally result in:

Despite these efforts, the issue persists. Any suggestions on how to address this? Thank you for your help!

Answer №1

To handle this situation effectively, my recommendation is to define the background color for the .pb-1 class within the primary component's CSS document. Each Angular Element will be influenced by general CSS styles (such as those from bootstrap) along with its distinctive CSS rules sourced from the component's specific CSS file. The latter pertains solely to that particular component and will not impact the CSS of other components even if they share identical class names.

Answer №2

Is the height of your body being properly verified? Keep in mind that the body does not automatically update its height when new components are added, resulting in your component's height being limited to that of the body itself. To prevent this issue, ensure you set the min-height of both the body and html elements in your global CSS file to 100% as shown below:

body, html {
  min-height: 100%;
}

Answer №3

Change the background color of the body element in styles.css

body {
background-color: teal !important; /*Replace with desired color */
}

You can also apply this to a specific div using a specific class
