Angular Universal 9 disrupts the functionality of Bootstrap CSS directives

My application runs perfectly fine with npm run start. However, when I try npm run build:ssr and npm run serve:ssr, it doesn't function properly without throwing any errors.

While running npm run start, there's a button with 65% opacity. The desired behavior is to make the opacity 100% on hover. https://i.sstatic.net/wZssV.png https://i.sstatic.net/gEdeV.png

The issue arises during Angular SSR build (npm run build:ssr and npm run serve:ssr) where the opacity setting doesn't work as expected.

Currently, I'm using a CDN to load Bootstrap by directly embedding the link into index.html:

<link rel="stylesheet" type="text/css" href="https://cdn.domain.com/bootstrap.min.css" />

I have confirmed that the CSS file can be downloaded without any issues.

Below are my angular.json and package.json files for reference:

angular.json

{
   ...

package.json

{
   ...

I suspect that the way Bootstrap is being loaded might not be correct. Any assistance or recommendations would be highly appreciated.

Answer №1

After some trial and error, I finally figured out how to make it work. The issue turned out to be the percentage symbol in the css code. For anyone facing a similar problem with opacity changes, remember to avoid using percentage symbols and opt for decimals instead. For example, %65 should be written as 0.65.
