Fixing the Display of Form Inputs in Your Custom Angular Material Theme

Creating a custom theme in Angular Material allows you to style your application to fit your design needs. However, developers often face the challenge of ensuring that all components, especially form inputs, are displayed correctly with the new styles. If you're experiencing broken displays of your form inputs after setting up a custom Angular Material theme, you're not alone. Let's dive into this problem and explore how to resolve it.

The Problem: Broken Form Inputs

You've taken the time to set up your custom Angular Material theme to provide a unique look and feel for your application. However, after removing the import line for the prebuilt theme in your styles.scss, you're faced with issues where all your form inputs are not displaying correctly.

Your initial setup might look something like this:

Removing the prebuilt theme leads to the startling revelation that the display of your forms and form inputs breaks. This raises a question: Why is the prebuilt theme necessary even if you have created your own?

Understanding the Solution

The issue arises because while you have defined your own theme, you might be missing some essential styles that Angular Material applies in its core theme. The resolution to your problem lies in ensuring that you include the core styles from Angular Material in your custom theme. Here's how you can do this step by step.

Step 1: Include the Angular Material Core

The missing piece in your custom theme is the inclusion of the Angular Material core styles. To address this, you should add the following line to your portal-theme.scss file:

Step 3: Verify and Test

After making these changes, it’s essential to run your application and verify if the form inputs are now displayed correctly. By including the core styles, you set the foundation for consistent styling across all components, including forms and form inputs.

Conclusion

Custom theming in Angular Material can enhance your application's user interface, but it requires careful consideration of the necessary components and styles that make up your theme. The core styles are crucial for ensuring that all components, especially form inputs, are rendered correctly. By including the -include mat.core(); in your custom theme, you not only resolve display issues but also ensure a polished and professional look for your application.

Following these steps should help you achieve the desired results. If you encounter further styling problems, consider reviewing the styles applied across your components and ensure all necessary imports are correctly set up.

Now, go forth and create an aesthetically pleasing Angular Material app without the worry of broken form displays!
